Thank you. Glad you didn’t have to go down the rabbit hole and saved yourself a lot of time and frustration. Definitely learned a lesson to compare the parts before I try installing them.
Excellent video - thank you so much for posting! 😊 I watched your video twice, took some notes, and completed the thermostat replacement in about 30 minutes. I wanted to add a few thoughts to this thread to benefit others: Why did I replace my thermostat? - My check engine light came on with error P0128 -> the engine coolant is not getting warm enough, fast enough. My mechanic said most likely the thermostat was not working properly. Once I removed the thermostat, I saw that it was stuck in the open position, so I knew that was the problem. What thermostat did I buy? - As recommended, I bought the Duralast 15238 thermostat from Auto Zone. I measured the new thermostat, and the correct, thick housing width is 11/16.” How much coolant did I use? - I bought one gallon and that was enough to replace what I lost when I removed the housing, and it gave me enough to refill the plastic coolant reservoir to Min level. How to reset the warning light? - Before replacing the thermostat, I had the “Check Engine” warning light. After replacing the thermostat, I now had the “Service Engine Soon” light. The easiest and quickest fix to remove this warning light was to disconnect the battery for 30 seconds. Once I reconnected I had no more warning lights on the dash.
Perfect review. couldn’t tell why my top radiator housing was getting so hot considering I just changed my thermostat and flushed my coolant. Checked my lower hose and it was cold after a 30 min drive. Had a faulty thermostat in and had to exchange it for a new one. Thanks again man 👍🏼
We’re does that hose connect to the lower resvoir hose mines just leak coolant out of it because it’s not connected to anything it’s that tiny hose that’s hanging up when you took the resvoir off
My g temperature gauge shows overheating after 10-15 mins but the temperature gauge flutters to normal temps then over heats and goes back and fourth ? Could it be thermostat
Well I recommend getting an Ecutek or uprev flash. Getting your fans to kick on in the efficiency range at 194 instead of a factory 213°F. Also the GKTech coolant bleeder pipe
This video is very helpful, thank you!! And on a side note, you need to make sure what engine type you have. DE or HR Hints why parts look very similar, yet they are very different.
I did a coolant change on my g and now it overheats after running it for 20-30 mins. I took out the air bubbles with the funnel you used in the video and it blows hot air any idea what it can be?
@@victorowoeye8238 it was very challenging , it took a while bit you basically have to depress two clips on each side of the sensor , I may have used a slim pliers to get it done , be patient and you’ll get it out
I have the reverse issue lol... The thermostat I received from rock auto has a thicker housing base and my bolts are too short... Went to AutoZone and put my thermostat bolts into the duralast one they had and the bolts were once again too short... Almost flush with the inner housing.

Good question. I would check the hose connections first ( upper and lower radiator Hose connections) and if those appear to be intact, I would look underneath the car to see if the actual radiator is leaking.
is it ok to bypass the thermostat, i have mo more thermostat in my car i cancel it, i live in a place where always the temperature is high and we run ac all time
Your engine is heated internally and the external temperature has very little affect short of below freezing, which you don't have a problem with. You're engine has a minimum operation temperature, and at the very least, your oil sump has to reach a minimum temperature for the viscosity rating of your oil to work effectively. If your oil stays too cool, it won't flow effectively and could damage your engine over time.
I have a 2007 Infiniti FX35 that’s overheating and has no heat at all and is back flowing into overflow tank. Top hoes super hot bottom hoes where thermostat is located and super cold. Today I back flushed the heater core and it was clogged. Changed the thermostat 2 times (same brand kinda thinking I should go with stock thermostat and will try that tomorrow). So is this sounds like a bad water pump? No sounds and no leaks from the water pump. And I try bleeding the life out of the system but it’s just goes crazy because the thermostat doesn’t open. Thanks
Hi, I’m not sure what the problem is.. I’m a weekend self doer, not a mechanic and only have basic knowledge based on the problems I have with my car .. I hope others that see your post may be able to help you
Go with an oem thermostat always and make sure you bleed the air out completely. Also on my Hr i had to slightly jack up the front end to help with bleeding the air out better. I was also having problems with my coolant backflowing into my overflow but wasnt overheating but kept losing coolant in the overflow. But when you say it “goes crazy” when bleeding the system do you mean theirs lots of bubbles?? Hopefully not a headgaskey problem. If you see an excessive amount of bubbles when burping the system then i would first do a Coolant combustion leak test and see if any exhaust gases are escaping into the coolant which means a headgasket problem. But start with the small things first get an oem thermostat trust me these aftermarket ones are junk for our cars
Not sure what the problem is. I would start off by checking to see if the lower radiator hose is hot like the upper radiator hose. If it’s not hot when the car is running for a while that may indicate a faulty thermostat.
@@ijostin5143 It wont overheat just from the water pump simply leaking from the weep hole but it will just keep weeping out until you start to get low on coolant then you will begin to overheat due to being low on coolant. Replace the water pump with an OEM one always

Awesome I’m glad this helped you!
From my experience it’s so much easier in the long run if I spend slightly more & buy the OE brand.
Your good man the way you unplugged that sensor was amazing lol mine hung up like Rottweiler on a poodle
Thank you!
I recommend buying from Z1 motor sports they have low temperature thermostat, or regular ones, grest video tho
did you use any gasket sealer for the thermostat?
Great job, thanks for your help 👍
In addition to the leak im not experiencing overheating but i dont get heat from the hvac

How many litres of coolant do you fill it with? and do you have thermostat and gasket part #?
Hello. I believe I out in around 2 gallons so about 8-9 liters? Unfortunately, I don’t have the parts numbers for the gasket or the thermostat.
Is your car not overheating while driving? Only overheating when it stop or park ?
Car was overheating all the time- driving and while stopped
@@Yourdoc1 oh ok my car only overheating while stop but if I rev it to 2k rpm it’s not overheating do you know what wrong?

Not sure
21200JK20A - is this the original part number? What was the part number for the correct part that you used?
Hello, I am not sure of the part number. It’s best to call the store and find out
My Thermostat bolts we're 9mm not 10mm, were yours 10mm? Also, did you just hand tighten your thermostat bolts?
From what I recall they were 10 mm. I did use a small ratchet to make it tight, hand tightening caused the coolant to leak out still
@@Yourdoc1 Yeah i used a small character to snug up the bolts, they don't have to be over tightened but ive seen people snap the bolts from tightening too much.
How did you get the clip off blocking the bolt
I used angled nose plierstook a while but it’s doable
Thx for the vid bro so I did all this exactly and after that the drive back home it was overheating again any idea what it could be?
Not sure, make sure there is no air in the system . Also are both the upper and lower radiator hoses hot?
What’s the part number to the duralast thermostat
Hello, I am not sure . Best would be to call autozone and ask, they only had one kind of thermostat.

I would've gone with the blue antifreeze that's recommended for aluminum block engines that won't corrode the aluminum like the green stuff does.
Interesting you say that. The manufacture rrecommends the green one, so I wonder why they don’t recommend a blue one

Bro how did you remove sensor
Please I need help I’m stuck
Hi, which sensor are you taking about?
Bro what happen to the bell use that at the end of all you vid
Do you have to add coolant to the reservoir after you finish bleeding it even thought the radiator has some in it?
you don’t have to but mind as well since you’re filling up the radiator
is this the DE or HR motor?
Hr is the double cold air intake and the single one is a de
How do you unclip the clip!!!
Which one can you specify the time in the video you are referring to?
Is it normal for it to go into limp mode
Limp mode?
No, this is not normal. Make sure you reconnected any airbox (or any other) electrical connections you may have disconnected.
