- Welcome to my channel In today's video I show you how to drain and fill a coolant system on a 2001 Chevy Silverado. You should flush your coolant system every 3-5 years or every 30,000 miles to to avoid any issues down the road. I did not mention the bleeding process in this video so before you take your vehicle out for a test drive make sure that hot air comes out of the air vents, this will let you know that coolant system is working properly and its safe to drive.

Hows it going guys hope you found this video helpful! I have exciting things coming so hit the notification bell so you won't miss any videos! thank you for your support, you guys are the best!
Hi Eric I’m doing the same thing you’re doing but instead of using distilled water, is it OK if I can use well pump water? I want to hear from your response ASAP.
Hi Eric I bought the same antifreeze+coolant but it has water 50/50 is that OK?
yes that's fine you dont want to use tap water because it has minerals that can eat up the inside of the engine and can cause rust
led lights for trucks
Hey Eric. I like the look of your tires. I live on some treacherous winter mountain roads. May i ask what those were?
Thanks for the video. My non mechanical dummy self had no idea where to start to change thermostat. Watched your video and now I’m a pro. Thanx!
05 Silverado. Drained/refilled twice in 15 years with Dexcool. Never changed a hose, water pump, or anything in the cooling system. About to do it again in a few weeks since it's been 5 years since the last drain/refill. Nothing wrong with Dexcool in these trucks due to the dry intake. If you have a V6 that has a wet intake, I could understand the concern since the Dexcool eroded the intake gaskets and caused a bunch of issues with those model engines.
Excellent video
Thanks
I use distilled water for the flush also
Thank you brother! Doing a radiator drain and refill and wanted to research more about the pitcock and it's location. I have the 350 vortec in a 1997 Chevy Silverado 1500💪💪🙏 Very well broken down, I enjoyed the 3 fluid displays in the cut plastic bottles. Thank you for helping me with my truck Brother🤘🤟💪🙏😇👍
To everyone saying he used the wrong coolant, Peak Long Life is not the old IAT silicated green, it's a modern OAT coolant and it's perfectly fine to use in this vehicle. It's chemical composition is exactly the same as Dexcool and I've used this and other universal OAT coolants in dozens of different vehicles over hundreds of thousands of miles with no issues whatsoever.
Name checks out
@@mattmatt222333 lol true
I was actually wondering about that thanks for the info I’m doing my truck this weekend
True. Its just universal coolant.. not the best, not bad either, just coolant
Thanks for the video. I'm installing a new radiator so I'll disconnect the upper and lower hoses, remove thw thermostat and then flush the system using the radiator hoses to bypass the old radiator.
Thank you! ...now I just gotta do this in in the cold weather
hopefully its not too bad thank you for watching!
me too, how was it in cold weather?
Good video man. I just did this process today. One thing you should consider is you never get all the water out of the system after a flush. When you drain your final flush there is a considerable amount of water left in the lines and heater cores and the block and heads etc... You should get a coolant tester and test your finished product because when you figure in all that water and add 50/50 to it you are not left with a final 50 50 mixture. More like 75water/25 coolant. Also i used only distilled water. I never hook a hose to my cooling system...Food for thought
Could you just start it with the hose off to get the rest of everything out?
To be sure the fluid is out of the block it is advisable to remove the block drain plugs. There is one on each side of the V8.
@@followerofchrist1961 On these engines the thermostat will be closed as the vehicle is not at operating temp. Unless you go through the added step of removing the thermostat you will still have fluid trapped in the block. The thermostat will allow a miniscule amount of fluid pass through but not enough to thoroughly drain the block. I let mine drain overnight just to see & then removed the block drain plugs. Yup, more fluid came out.
@tonylopez9936 where is the block drain plug located on these vehicles?
Thank you! This is what I have to do. I live in Vegas! Been hot as F out here.
I would recommend removing the thermostat when flushing out the old coolant since you can then do a number of good flushes without getting the engine too hot. You don't want to refill a hot engine with a cold liquid, a friend of mine cracked his cylinder head doing just that.
Dam
Thank you for the wisdom just did mine and it worked fine. Removing the thermostat before I started process. Thank you for the wisdom bro.
removing the thermostat on these trucks is a royal pain, not worth it unless you need a new thermostat
@@jc13781 No it's not, lol. Remove the air intake and it's in arms reach.
@@yourface3154lmao not that simple
Good video!
The "car again" or actually (insert Man Voice) The TRUCK! 🤣🤣
Good job man , great video thanks
Thanks bro helped a ton with my dads 06
Thank you. Going to do it one of these weekends.
Tap water is fine folks. Thanks for the info on the drain location and I was thrown off on the whole no radiator cap ordeal so thanks for the good vid man
That was proper. Thank you.
Great video bud
Thank you so much bro for the video
Thanks for the video. I haven't flushed my coolant on a 2002 sierra 1/2 ton so this video will help a lot!
thank you for watching!
@@ERICSDIYGARAGE The plastic inlet snapped off due to age and dumped coolant everywhere. I thought I'd have to replace the whole heater core. I'm glad to see I'll be able to fix it myself tomorrow.
I gotta do this to my dad's truck, thank you.
Ive had the original dexcool in my 07 gmc sierra since i bought it in October of 06. Thats 14 years. Still runs as cool as it did when it was brand new. Gm changed the chemicals on dexcool in 04 I believe. Doesn't ruin the gaskets no more. As long as you don't contaminate it with another coolant, it works like it supposed to. But if you mix another type of coolant by accident you need to flush the system immediately.
Mixing coolant doesn’t do shit
@@alecsanderfuentes3913 Well, actually it does. You can not turn a 2 year coolant into a 5 year coolant. Add a 2 year coolant to a 5 year coolant and you dilute the 5 year coolant. So that proves that adding chemicals has a reaction period. I am told that the newer coolants don't react as the older formulas that turned into a gel & clogged radiators, etc... And it was already mentioned that the red used to affect the gaskets on the v6. You can take a chance with your truck but my pockets aren't that deep. I think Ghostrider has a more salient sugestion.
Great video, thanks for the info. Im doing this exact thing on a truck just like this one.
thank you for watching🤘
Thanks much. Did think to turn the heater on. I have 2001 tahoe i bought new and we still love it. it has the original coolant, so I thought I would be nice to it today. thanks for the video. From Augusta, ga.
thank you for watching!
You do NOT have to turn heater on as coolant always runs through heater core, even when heater is off.
Your lucky you ain't walking...15 years on the same coolant! That's as bad as not changing your oil!! Are you lazy, or just dumb lol
Drain and fill with the water a few time, what do you do with excess water? Is it cool to let it drain after you get the original coolant out?
The coolant used here is a OAT coolant thus it is a DEXCOOL clone. So DEXCOOL was replaced with a near identical DEXCOOL copy. Good job.
Normal temp gauge right in the middle? Mine right now is at 1/4 of gauge. Suspect that to be 185 degrees. What temp is your thermostat sitting at now? I am asking this now since I had to replace my radiator and thermostat and seeing a low temp reading.
I was expecting to have to remove the lower hose, we all know how fun that is. Thanks.
Great video. I’m going to try this on my ‘07 Silverado classic 2500. Does 2.5 gallons include 50/50 of fluid and distilled water? Thanks
is that drain hose already there? or did you use one you had lying around? Thanks
Is dextrose garbage. I've seen videos where people say it clogs and causes problems..can I use a 50/ 50 blend? I have a 2005 5.3l 1500 v8 vortec. Have to change radiator
My question is how do you install a flush kit on a 98 Chevy pick up. The truck overheat but sometime when you come to a stop the gage go back to the cool side.. I have replaced the water pump and the thermatat..
Nice video, although honestly I was hoping for a block flush video with thermostat and engine block drain plug removal.
Thanks, just saved me 7 min, looking for same
@@ktajax I found the plugs... one under front drive shaft, other under the starter. In my opinion it was not worth removing... the starter was a royal nightmare to reinstall. Just remove your thermostat housing, drain, remove thermostat from housing and reinstall housing. Run and drain with distilled water a few times and you're good. Reinstall your thermostat when you're done.
Please don't add cold water from your garden hose to a hot or warm engine. The difference in temps can crack a block.
Feel real stupid for doing it but just went through that a couple days ago, now I’m in the process or replacing my radiator 😓
What if it's not cold but indeed hot ?
Use distilled bottled water not tap water. Tap/garden hose water has minerals in it and will rust cooling system. 👍
@@benjaminruckman6352 your local water utility can tell you whether or not the local water has too much mineral content to use in your radiator.
lol why don’t u crack a block when u go through a big puddle then lik
so if a man wanted to do it right would he flush say 4 times with distilled water and then the 5th time flush with 50/50 & drain? then finally proceed to fill cooling system with 50/50 & call it good?
I have a 2004 GMC Sierra 1500. That is the first vehicle I ever met that doesn't have a radiator cap!
How far did you unscrew the drain plug?
THANK YOU....
I have a 2003 Chevy Silverado SS and it does not have that valve with the little hose to drain?
I’m sure you know this but for people who don’t, GM antifreeze is orange. There may be an aftermarket antifreeze he is using, but don’t be alarmed if it looks like that coming out. OEM antifreeze is rusty looking.
@3:33 you're going to fill up the reservoir with *distilled* or *ionized* water. Don't use tap water to flush out the cooling system. Ionized water is better but you can use distilled.
I think you mean de-ionized.
The manual says distilled water is bad!
@@jmitch6764 Yes *deionized*
Ima just put fiji water in my truck
You're not supposed to RUN it with straight tap if you somewhere warm enough that let's you get away with it, a flush isn't going to give your water jackets and thermostat enough time and heat to strip the calcium out of the water and mess up your block. I think my favorite thing I've seen is watching a guy pull all the water hoses completely and run a garden hose to the radiator, heater core, and block individually and watched it pump out all the gross crap that doesn't come out in a regular flush.
Would this process be the same for an '04 Silverado? I have the same symptoms you were talking about: engine overheating, cooling down again, and intermittent heat from my vents. I'll get the coolant + antifreeze this weekend along with the distilled water.
Did you seal the radiator drain plug when you flushed the remaining coolant with tap water the four or five times?
Yes this process should be the same on a 2004 Chevy Silverado. I close the drain plug four to five times to let it circulate the system. But you can leave it open and just put a hose in the radiator and flush it out that way but I feel like you won't be able to get all of the water that still inside the heater core or the engine
@mike benfer did you ever get this fixed/ what was the solution?
About how many gallons of distilled did you use for the flush?
I have a 2000 Chevy Silverado 4.3 v6 and wanted to change my coolant there is still coolant inside the tank but I unscrew the cap off the tank put a drain pan under and unscrewed the screw from the radiator and no coolant drained but I looked back at the coolant tank and some coolant was gone what could this be?
thanks
Thank you
Orange is what gm recommends. Yes that old fluid was bad but I’m doing the same thing but putting in fresh orange
Dam got to do this this weekend just bought the truck used and the resioviour is dirty as hell
Saved me a truck bro
Just me or did the flush work so good tr k changed color
Hilarious !
Looked like asshole yellow to me
1 clear water flush will get you to 99% free of the original charge of red 50-50. 4 X flush is unnecessary. Modern coolants have rust inhibitors and additives to inhibit mineral crystallization, so it is perfectly fine to flush the system with tap water.
Can you remove the thermostat without draining the system?
I hope you’re still active but do I need to add 4 bottles of coolant? Or just one?
how many gallons of dex coolant do I need to buy after replacing the water pump?
Depending on engine and year? 3.8 to 7 gallons total.
Everything on my GMC says use Dex, I don't know for sure, so I will stay with Dex but Green coolant is a different chemical mixture than Dex. May not be the best thing to do for your engine. You should consult a reliable mechanic and get their opinion. The outcome may not be the best changing from Red/Orange to Green for your truck's internals!!
I've read that DeX is no good, eats gaskets, etc. Changed to green years ago, no issues. I think most green now is universal anyway.
Ive use green on my 2001 Tahoe for a while now. No issues at all.
Been using green coolant in mine for 12 years. 5.3 engine. No issues at all. 244k on original engine. But with that being said I think it's fine using dex cool and I don't see any benefits to me switching over other than cost.
Yeah me aswell iv always heard even from school that switching up the different color coolants they have the different chemicals sorry for not remember but I think it’s the ethylene glycol acts differently to the plastics vs propylene in the specific systems, again no experience in the manner just what iv been thought through school so I have steered away from the swap
Dex Orange is made for Aluminum engines because it doesn’t corrode it, the others might though that is why for aluminum blocks only Dex Orange is recommended.
why does mine keep leaking out the drain hose after i turned the drain plug tight
Could you just leave the radiator plug opened at the bottom and just keep putting water in it until its clean and ready for the new coolant??
the reason you dont want to do that is because the coolant needs to circulate .
I agree with you. It will still circulate. People have been doing that for many years. You can also purchase a prestone flush kit that back flushes through the heater hose.
Doesn’t this mean after the whole syestem cycles and drains u still have water in the block and ur adding 50 50 with the engine filled with water ? How do i know the engines completely drained ?
Is there another way to fill the radiator? I put new coolant in my resivor but it looks like the coolant level won't go down and into the radiator causing my truck to over heat (05 Silverado 1500)
you might have air in your system squeez the Hoses and turn the truck on and keep squeezing the hoses to see if the level goes down and into the radiator
Still nothing I might need to replace radiator
It was the thermostat
@@joseesguapo chiquilin
My radiator wont drain fluid.
It has radiator flush in it and the reservoir is half full.
I unscrewed the drain plug but nothing comes out just like 3 drops, any idea what I did wrong?
Open your radiator cap
@@SomebodyOrNobodyIDK turned out radiator was clogged and I needed i to replace fan clutch along with thermostat
Thank you💪
Thank you for watching!
I went to 7-Eleven store and got coolant that was mixed water-based with the coolant mix cost me money but exactly what you had in a video. Thank you I'm new to Suburban thing was on empty on coolant bone dry.. you saved me with this video today💪💪 after this video you saved me because I checked my truck after this show..
Im glad I was able to help you with this video 👍
I have an 07 Sierra there is no drain plug on the radiator I guess I'll just take off a bottom hose right
For some reason some radiators won’t have the drain plug,I have a 2005 Tahoe and need to replace the radiator and don’t have the drain plug, so is what I do remove the bottom hose
Approx how much liquid came out of the petcock? Need to know how big a pan to have.
SO YOU DIDNT USE DEXCOOL? LOOKING FOR IMFORMATION SINCE AM DUE FOR COOLANT CHANGE 2007 TAHOE
Use the orange not the green in newer gm vehicles.
Could i just buy the 50/50 coolant instead of mixing it like you did in the end? And where did you take the hose off that’s leaking the coolant into the pan?
Also great video! Extremely helpful
It's the same price for either, you would be wasting $18 on another bottle, but you could if you wanted to
@@csmith6237
What about that hose tho
This truck is going to hold 16 quarts. That’s 2 jugs of concentrated coolant and 2 jugs of distilled water. 😂 just pour a jug of water and a jug of coolant and it will mix on its own thanks to the water pump 😂
Lol exactly
When you drained the straight water out, some straight water remains behind. A final fill always add straight concentrate antifreeze up to 50% of system capacity. So when it mixes with the water, it ends up being 50/50. If you fill with 50/50 you may end up with 30/70. Test your final xix with an antifreeze tester with floating balls. They are in expensive.
it does not need to be a 100 percent 50/50 mix. you want to get close but it's not going to make a difference.
@@ERICSDIYGARAGE not 100% 50/50 is less than 50/50. I guess it depends on the level of protection you can be satisfied with...
@@TheBrushcutter It;s a good idea to test it after a few days
It doesn’t not need to to be 50/50 you can even run your truck with nothing but water if you want if you don’t live in cold weather. It’s called antifreeze for a reason
@@ERICSDIYGARAGE tbh the 4 or 5 flushes really aren’t necessary. A solid 1 or 2 will do just fine and the little remaining antifreeze won’t barely make a difference. If anyone is low on time just flush it out with water and let it run for like 5 minutes and then re add the antifreeze. Most times you need to let the antifreeze run through a little and then add more to make sure
So you have your lower hose unplugged and your thermostat still in. Are you running the engine at any point of time without water in while you flush the old out. My question is I am running for 25 min the unplugging lower radiator hose which only releases half, is there a better way besides removing thermostat?
the bottom hose is there for a mess free drain when you remove the radiator plug all the way the coolant will come out of the radiator faster. this is why you have to repeat this process multiple times
@@ERICSDIYGARAGE so each time you flush your only getting half, that what I'm getting
the coolant will mix with water to the point that it will be mostly water.
Roughly how long should this take?
When I squished one of the hoses i heard a crunch im guessing its like some sort of debris is that something to be worried about?
Calcium build up,. That stuff can look super nasty. So some hoses have metal coiled inside to kinda let the hose stay a certain shape. So it doesn't bend and kink.
Some years for Chevy hoses have a spring built in to stop the hose from collapsing under pressure from the water pump. Especially the bottom hose.
Why did you change from dexcool to the green stuff?????? just curious
Ten years after General Motors began using Dex-Coolas an antifreeze in most of its cars and light trucks, GM car and truck owners continue to complain that the coolant corrodes and clogs radiators and radiator caps, erodes water pumps, rots radiator hoses, causes chronic overheating and engine damage
@@ERICSDIYGARAGE ohhhh ok gotcha..maybe that would explain why i have the green stuff in my 05 denali i just got, cause i was gonna flush that and put back in the dexcool...thanks for that info
PlZ help! I took the drain plug out on driver side radiator and nothing is coming out. I kno I have water in there. I accidentally put just a little synthetic oil in my reservoir. That's the whole reason I think I need to drain. But the there's nothing coming out of the small drain hole. I have an 03 silverado
Disconnect the radiator hose from the bottom
Nice Video but do you have do all that you said repeat the process 4 times
thank you for watching, if you want the best flush yes
Thanks
Didnt understand why you converting to the green coolant when the system calls for dexcool
it doesn't matter what coolant, as long as you completely flush out the old stuff. Some guys don't like dexcool because of the gasket failures. Its a personal preference, but you can do it
@@HeavyDutyHauler ok didnt really know, a buddy of mine switched over from green back to orange in his caddy a short time after engine was done
@@HeavyDutyHauler but thanks on that good content!!!!!
Tommy Woods HeavyDutyHauler isn’t correct on this one you can’t simply just put whatever coolant into system. You should put what your owner’s manual calls for. That may have been the case for older vehicles. But now days manufactures make blocks with different metals and some engine blocks due to the different metals may require more rust inhibitors than others
@@geroldgerry3375 Gotcha
My 2006 silverado doesn't have a drain plug on the radiator like the ones that are being shown in videos. So what is the best way to drain the radiator?
Remove the radiator hose
@@ERICSDIYGARAGE you mean the lower radiator hose?
Thanks
Shouldn’t you use the same exact color coolant in there the orange to replace and not the green or heard green is for cars in oranges for trucks
That petcock (drain plug) was on the Left side.. Left & Right is Always from the drivers perspective.
Good Good. GM could keep their dexcool.
You must not be aware the long life all makes and models is DEXCOOL clones.
Dexcool is fine as long as you don’t leave it in too long. Changing a GM car from Dexcool to the green stuff is not a good idea.
Is that a 2002 bro? I own a Chevy Silverado 2002 with a V8 6.0
Nvm I just seen what you said
I ran pure water in summer never rusted up the engine I don’t recommend that for everyone but these 6.0 are pretty tough I was only running water due to slow leak in the radiator but I also own 4 cat eye 2500hds so don’t care if it blew up I’ll swap the engine lol but when I tore It down building it no rust so don’t worry to much about water in there, but get the green out of there the vortecs really do better with dex
Well it seems like a very good way of flushing the vehicle problem I see is when you first drain the coolant it doesn’t all come out you obviously have to add water five or six times and after doing that you finally get all the coolant out well I think you i’m going to have rust problems like you said because you flushed it very thoroughly with tapwater now you drain it like you did the first time and start adding coolant well guess what that tapwater is stuck in the engine now so you probably have a gallon to two in the heater core etc. that’s going to mix in with your distilled water and coolant just my two Satoshi‘s.....
In his video he used distilled water. Did you not see the gallons
@alecsanderfuentes3913 no he used garden hose for flush. Distilled was for the 50/50 mix
Can a dirty radiator make the guage stick?
No
Did you check the thermostat?
Thermostat had already been replaced
I was told by Carquest to use full strength coolant because of our cold weather driving in the north.
Yes I'm from North West Indiana and winters get ccccold I run at least a 70/30
I'm sure someone else caught this guy pointing at the oil pressure display saying "the temp is in the middle" ..?
Can i do this to my 2008 Chevy Silverado?
This process applies to 2000-2006 it might be very similar though.
Thanks man. My owners manual says to use Dex Cool, do you think converting it to the Peak Green Antifreeze is better than Dexcool or do you recommend just going by what the owners manual says? Bought my truck used and don’t know what to put in it. Thanks again.
You can use both as long as you do a Coolant flush as show in the video. Do not mix avoid issues
@Jesus LovesYou wow for a name like you have you sure got a mouth on you. I would only use the orange. When you get away from factor OEM items you start messing up. Just leave it original. Why test it to save a couple of penny's?
Any truck made after 2000 take dexcol that one put in it is for older cars that still take that
dex cool is shit
GM Recommends Dex-Cool Coolant (Orange) Not The Green Color . Thanks for video though
yes recommends but not required. thank you for watching!
They reccomend, I recommend getting rid of that crap. Complete flush and change. I converted my vehicle from dex cool.
Roughly how long should this take?
All day
@@wdsracer not true😂 I did it in 45 minutes
Well your temp was ok but that was your oil pressure that you pointed to. And why would go from Dexcool to green ? What's the reason I'm wondering?
Tens years after General Motors began using Dex-Coolas an antifreeze in most of its cars and light trucks, GM car and truck owners continue to complain that the coolant corrodes and clogs radiators and radiator caps, erodes water pumps, rots radiator hoses, causes chronic overheating and engine damage.
ERICSDIYGARAGE having 1 truck that has 120,000+ miles and 1 car with 15,000+ miles haven’t had a problem with DexCool or anything that it is in
Catch can Lol
fyi you messed up with that peak coolant jejejejeje
I just changed my radiator and my lower hose fills tuff like nothing getting thrue and now some coolant leaked out near my ac condensor silver can close to the frame wall, theres a lil hose ...it took all 14qts fine but it wont let me fill the reservoir tank stays at the bottom. What you think
The red/orange antifreeze is better for your Chevy. It's the type that your suppose to use in your truck
Actually there’s another green brand that’s 50/50 and is useable on pretty much any regular day vehicle including my mustang and Chevy
Damet bobby why did this require that many drainages ?
OCD mechanics
Yep frickin meth heads 😅😂😂
I twisted that and ntn came out
3 words. Aluminum. Dex. Cool.
A easier and faster way is to pull the thermostat out while leaving the top hose of the thermostat housing..take a garden hose and place in the upper radiator hose and run the engine and it will flush everything out faster. Then run the car until all water is out
You will need a new gasket if you do it this way. But yes, I agree it's faster
The integrated transmission cooler in your radiator is leaking into your cooling system that's why your first sample was heavily contaminated like it was
What do you do to fix that issue and what should I look for if its contaminated? I.E the color or a oily substance? Thanks for your help.
@@brandoncuts82 the integrated transmission cooler is inside the radiator... if you follow the transmission cooler lines you'll see they connect to the middle ports on either side of the radiator "engine facing side"... if the integrated transmission cooler is leaking into the coolant system portion of the radiator id suggest swapping the radiator completely, check/drain the transmission cooler lines and verify they arent rusted to shit... if your lucky enough to live in a rust free climate all the better. Had to fix a mechanics cob job and discovered rusty transmission fluid in my transmission cooler lines. Apparently had a blockage inside the intergrated cooler and he just bypassed that all together without plugging the holes and hooked up another auxiliary transmission cooler lol found out during winter when moisture got into the intercooler and froze cracking my radiator... turned into a fun under a tent driveway project 🤣
@mm-nl3qz how does one know if transmission fluid is in your radiator? I have brown sludge in my radiator but I figured it just got dirty and needed a flush. How would I know for sure that it's from the transmission cooler line?
can you change the color
You have to make sure all of one color is fully flushed out before adding the other color, don’t mix red and green, they’ll turn into jello and plug everything up.
I wouldn’t recommend converting over from dex-cool ORANGE (not red) to the cheap generic run of the mill green. Dex-cool goes in all GM cooling systems for a reason. Everything to do with the cooling was designed with dex cool and its properties in mind.
I agree
It doesn’t matter what you put in it
Very true! There are a lot more reasons than most people know, why you NEVER switch a system over to the green when the system was designed for the DeX. There are no good reasons to do that... well except for ignorance... 🤷♂️
a good reason to switch from dex is because it becomes sludgy and corrosive to gaskets after ~6 years. gm lost a lawsuit over it. its perfectly safe to switch but only with an extensive flush, but mix dex with green and your gonna have a bad time
I only put the orange in mine but that’s just me
