I just went through 7 gallons just to get back home so this is going to be fun.
I did 3 gallons damn this sucks
As long a we don't see white smoke we're good
Oh no.... I did that with my 99 Ford and it had dumped ALL of the coolant & water into the oil. Checked the oil and it looked like chocolate milk

@@ortiznick1941 couldn't even fill mine up felt like I was pouring coolant into a bucket with a hole on the bottom😂

On my honda I'm having a external leak idk where it could be coming from seeing as I replaced my radiator and coolant tank along with the coolant hose might have to check the lower hose
this dude is really helpful
Great video!! Very helpful
Do you have a link to the pressure tester you showed on your video? That would help. I have a coolant leak that I am having problem locating on a 2010 Jeep Wrangler.
Great video. But how do you do pressure test with a coolant reservoir only system? Thanks
Connect it in there
Good job thanks
+Azar HM Thanks for checking us out!

I loved all of 1A How-to videos. I detected a coolant leak from my Nissan 2001 xtera SUV. I saw a lot of steam smoke ( vapor) came out of the back engine around the oil filter and back if top engine block. I was unable to pin point exactly where the leak actually came from since I do not know the coolant system component arrangement on my Nissan.
Think you can help sharing some video tips ?
Appreciate a lot.
+Mi Lo We do not have a diagram we do apologize but we appreciate you watching our videos!
I have a 2006 Saab 97X 4.2 a.k.a. Chevy trailblazer and there’s coolant leaking from behind the power steering pump near the engine. When I say behind, I mean, if you’re looking at the power steering pump from the passenger side tire. The water pump was done recently and VIP auto said that it wasn’t the water pump. They claimed that it was the transmission cooler lines but these all seem fine.
thanks for the help
great video
Can you do a video on how to replace an egr valve on a 2007 mazda 6 I. I recently took mime off the car to clean it but I think I may have cracked the gasket. It's leaking radiator fluid from the bottom of it.
You’re amazing! Could you show where it might be/ steps to fix this if it’s an external leak near the head gaskets?
There is no solution for that short of taking the engine apart at the head.
You sure know your work. Thumbs up. Will you advice i remove my car's (Toyota Camry 2001) thermostat?
I have a 2011 Nissan maxima. I noticed that the temperature gage was all the way up there on hot causing the car to overheat also on the passenger side under the car there is a slow leak with green coolant. Would that be a hose problem or water pump or head gasket?
Older great running 5.4L Triton- appears to be a leak from the weep hole on water pump. Hard to tell once that fan sends that coolant everywhere. Here's the mystery : the leak stopped on it's own. Three days after the leak and loss of 1 gallon of coolant- it hasnt leaked one drop. Because of the thicker concentration of evidence I still think it's the weep hole or that rubber with metal fitting hose nearby. Any help greatly appreciated. Thank you.
My Chevy Colorado started to leak coolant yesterday so I went to check it out I noticed the leak was running down from the engine not any hoses or clamps. So my truck has the big engine fan and it connects directly into the engine and that’s where the leak is coming from,what could this be what should I do does the engine have to be removed. 2007 Chevy colorado
gr8 vid ty
Good explanation
Would pressure drop for an internal leak also?
Best video I've found
Thank you so much. My leak is coming from the coolant water. And smoke gets really bad and fast. Can I my car to the mechanic?
What about ac compressor leak should there be any concerns I have a compressor leak but vehicle not overheating just every time I drive a small puddle
I have a 2017 Buick encore with 32,000 miles and I have a cooler leak under the car and I can’t find it, any suggestions? I will really appreciate it. No radiator or hoses leaking.
I bought my 2004 Tahoe new and within a month the heater core had a leak on the passenger floor. The issue never returned, but recently I have developed a leak in front of the tires. I assume that it’s the radiator, but looking under the hood while the engine is running droplets are coming from the center of the fan. Need to get it handled soon since it leaked on my belts.
Recently changed coolant in camaro 2014 RS to dexcool acdelco . However everyday when I open the radiator cap I see coolant gone low in cold start . so I top up with coolant (may be 100ml add).
Don't know where the coolant is going , no leaks on bottom area.
Is there only 1 pump in coolant movement or any other ?. No leaks so far on pipes or on the hoses. Seriously it's getting my mind worse as I cannot find the reason for low coolant. Any help will be appreciated
Good video.
What brand and style of safety glasses are you wearing? They are pretty sweet
Heat wave makes some like those.
The only other question is what besides tester is that radiator color changing (if carbon monoxide) is present?
Be safe using hydraulic lifts when working under vehicles always check hydraulic fluid levels every day to avoid losing co workers or family/friend doers do to non consideration of this issue stay safe and busy my friends
I recently had a clear leak under my toyota corolla, the fluid had a very slight oily feel. When I mopped the leak from the concrete garage floor it left a very white chalky residue. I now don't see anymore leakage, what could this be ?
My 2003 Ford Explorer xlt is having a problem it doesn’t over heat but once the car is off coolant pours out of the car we can’t figure out where can you please help
3:26 is this seal, where the plastic meets the aluminium, something that can be replaced without replacing the whole radiator? It sure looks like that’s where my leak is ever since a deep freeze a couple weeks ago.
My 2010 FX35 Reservoir goes over the Max line, i replaced the thermostat with an new OEM and a OEM Radiator cap. I don't see any spills, or smells or smoke. I have to siphone it from the reservoir and put it back into the radiator. The car does not overheat or has never overheated.... i'm at a loss right now.
I have a antifreeze leak to and apparently nobody could find out where it's coming from and every time I park the car there's smoke coming from the engine from the antifreeze
I got a 2001 chevrolet van exspress 1500 I changed the thermostat and the waterpump it still is leaking all the coolant on the ground it dont show overheating at all tho
This just gave me a panic attack I came thinking hoping it would be too bad…and there’s like 10 million different possibilities where the coolant could be leeeAKING FROM AAAAAHHHHH 😭😭😩🤪🤪🤪 lol thank you for your knowledge it was extremely helpful tho and sounded pretty confident ❤
Front right leak under the radiator
I have a 98 chev truck and Im so happy that a lot of their videos are on a similar model. But what does that tell me about my Chevy truck hahaha
I bought the combustion test and didn’t get any color change on the radiator. I changed the thermostat because the pipe that was connected wasn’t hot. But the car is still overheating while idling and stays in the middle. Idk what to do next….?!
In Chicago check for leaks from the bullet holes in the radiator.
This guy can teach me to do anything

Thank you... the seal is leaking at the seam on the radiator 👍🏼
+Connie W Thanks for watching!
I have a 1990 Chevy Silverado 1500. I have noticed that I have a potential coolant leak on the right side of the vehicle dripping behind the right tire. What do you suspect it to be?
an expansion plug or "freeze plug" . its a potiental place to check for a leak. this "A-1" mechanic must not be familiar with engines, but he seems to do well with the camera..
I have 2015 ram 1500 5.7 hem motor the cool is milk but ti is not smoking and the motor oil does not have milky inside of it
i have a coolant leak for sure but i can’t find where it’s coming from but with puddles on the right side of my car i hope someone can help. (pontiac g6)
What does it mean if antifreeze leaking inside of your car?
Excelent video!! Can You share the sales web site from where i can buy the tools that you told us to used? (Internal coolant pipe and external pressure test ). Many thanks, regards from Argentina
+dexthor weighlifting These can be purchased at any local auto parts store or Harbor Freight tools. Thanks for watching.
Got radiator fluid dripping from bottom of engine block any ideas
i have coolant coming out from where my bellhousing is what would be the cause of that?
I towing my nissian xterra and while on back of truck the radiator fluid and water drain from tail pipe. What could b causing that
Leak in back of engine could be small pin hole in freeze plug
what are your thoughts on stop leak products?
What about the freezer plugs...or seals?
I have no drips it pours right out when pouring in, what do you think
my duramax leaks out of the reservoir but not out of the overflow seems like an only me problem bc i cant find anything on it bc its not mixed it all with oil like everybody says its just clean coolant that pours out after i stop and having a constant low coolant light after i fill but as i said its all coming out onto the ground not in my engine
Did you fix it
Excellent information for a repair. Thank you.
I'm at wit's end here. 2011 Cadillac SRX 3.0 was throwing P0430 & P0420 codes and started running hot, so had the 2 cats replaced. On the way home from the muffler shop, it started overheating and broke down. Towed home. Filled reservoir 1/2 way with coolant and immediately coolant was all over the driveway and 10 minutes later the reservoir was empty. While this was happening, the combustion leak test was performed and the blue liquid did not change colors. Now, the vehicle is not running hot, not throwing any codes, and the reservoir is empty. I'm afraid to drive it. How do I get the gremlins out of the coolant system?
Hi there. i have a bad leaking and bought a radiator cap and it stopped. but then in a week i notist theres a small leak coming from down the side of my antifreeze container it happens when i turn my engine on with the key. and as im driving it kinda shakes out sudden but it stops. some might know what it could be??

Needing answers have 2008 chevy equinox antifreeze keeps leaking along after I put it in by front driver side I need answers I'm being told it's the intake manifold gaskets
My car failed step one. The cap didn't have a spring or anything, it was just a normal screw cap. Can someone please tell me what to do? Im busy trying not to have a breakdown because we're poor and I don't know a thing about cars.
My Honda Pilot 06 is leaking antifreeze. Looks like it’s coming from under the engine. I could not really locate the source of leak. A couple of notes here:
When it starts dripping, it overheats
Any suggestions s?
One week later.... what did you find?
Can you have an internal coolant leak without having white smoke or any smoke coming out the tailpipe
Plz tell me what is the pipe in front of radiator????
Anyone else like how he says Vericle?
I believe I have an external leak. I have puddles in the driveway. Plus I have to add more coolant at least once a week.
Me too
Any update ?
Dodge Dakota 2000 just came out getting ready to get in the car I see something spilled under the car I take a look closer, it is radiator fluid beneath car

God, I wish I knew what’s going on with my girlfriend‘s car. Randomly today she just started pouring out coolant. No signs of any issue. No white smoke just started pouring out when you refill the reservoir you look under the car you see it coming right out😭
When I turn on the AC coolant is leaking under the engine. what could be the issue
I just replaced the water pump on my 1999 Ford explorer but it's still leaking. What do I do now?
Got an exterra 2004 has rusty water in the radiator caused a hose to burst I replaced all the coolant hoses but then the next day I noticed a big leak but it isn’t any of the hoses.
Is it possible that the rust water messed up the water pump gasket?
+Raid FYB We wouldn't be able to diagnose an issue like that here, you may want to have a local mechanic take a look at it. Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
