My 90 GMC Sierra runs fine until I'm in heavy traffic with the AC on. Changed many parts already except radiator. I did take my infrared thermometer and I did see a difference in the radiator temp. SO, I'll be changing it out tomorrow. Thanks for posting sir..
Had the same issue. Had the engine overheating light pop up when in heavy city traffic first then it popped on as well on "empty" roads. 2 days later I changed the radiator. When playing around with the old radiator could see water going in at the top but only trickling out at the bottom.
This was quite handy. Thank you. It gives me hope for my 2000 Ford Mustang v6 3.8l engine...otherwise, as process of elimination goes, water pump, fan, 😢 head gasket...oh my!
This was really helpful. I JUST bought 05 civic a week ago...... Theres no cap on the coolant reservoir (ive ordered one) .... And the car overheated, steam rolling out. Checked coolant level, it was OUT. i added coolant.....and it hasnt fully overheated, but temp guage creeps up very high when im going 40 or less.....and the big thing is a bunch of gunky coolant is coming out of the coolant reservoir (remember it has no cap......theres a radiator cap, just no reservoir cap) and its all over tha place underhood. The oil dipstick looks perfectly fine ..... Do you think this sounds like clogged radiator? Not al blown head gasket right?? Sorry......single mom here, just trying to make this car last.
I would get the radiator replaced. But if the coolant is coming out of the reservoir that means that it is flowing, which means that it should not be clogged, according to this video. You did state that the temperature gauge was creeping up. This would indicate that the engine is not being cooled. How about the water level in the car? Water is also needed to cool the car down as well.
I used head gasket sealer. 3 times haha. 2 blue devil one k seal. 2010 corolla. My radiator was clogged. Partial clog. New radiator fixed it. No overheating.
If not clogged warm coolant will flow back from the (lower) radiator return pipe. One other symptom is fan not starting because the extreme heated coolant from the engine that passes the thermostat won't properly flow through the radiator so hot coolant won't reach the radiator fan switch?
The very last tip you gave -- warming up engine while leaving radiator cap opened, I noticed the coolant started to slowly move upwards and leak out only within under 1 min of starting engine. Would this be a good indication of a clogged radiator? Coolant color & consistency is clean & clear, no rust build up anywhere. No leaking problems. But I had a overheating issue & loss of power to engine during acceleration, which caused overheating w/ white smoke on passenger side of engine. Been trying to diagnose the problem before I buy parts or go to a mechanic. First thing I'll do is change out the dirty air filter I had on this 03 Civic. Any suggestions would be helpful! Thanks for the vid.
I've replaced my water pump, thermostat, burped it, new radiator cap... Still overheats, but not like when you said... one the thermostat opens up the temp gets all the way hot in a few minutes... especially when accelerating or going up a hill... could this be the radiator still? Thank you.
@@alwaysforever-y9c after all that problem was the antifreeze: I got it from the dealer mopar I thought I don’t have to add water so just last night I add one gallon of distilled water thanks god
My thermostatically controlled radiator clutch fan stopped coming on. I thought this was a problem and replaced it however had no effect. Also replaced the water pump, thermostat, and hoses. After a week of work and $1000 in parts, it turned out. It was a plug radiator. Not enough heat was coming through the plug radiator to turn on the clutch fan. 1:09
Have an 03 f150 and it will get hot in winter then go back to normal immediately, blows cold till it goes back to normal then blows hot, changed thermostat, waterpump, overflow cap and still does it. Any ideas? Also on warmer days it won't go hot at all just goes to normal.
There could air in the cooling system, coolant level probably low, heater core probably clogged and I guess you already mentioned thermostat replacement. Stuck open thermostat can also cause all those issues.
I have this problem I just bought a2009 Audi a3 the guy have aleak so he just was adding tap water well I fix the leak the water pump and I did find a lot sluggish dirt so now I put coolant and the car overheating in stops red lights if I move temperature gos back to normal another this if is in park won’t overheat and the sones I put in drive gage star to overheat and another thing if I’m park if I put the AC car star to overheat so now I’m thinking is maybe the radiator anybody knows?????
What does it means if when open drhe rad cap when cold and the coolant would not move at all, and after reaching around 180 degree at the upper radiator hose the coolant starts to spill dramatically thru the rad upper hole? It does spill the coolant like 2 feet high. Im troubleshooting a temp needle going from half to 3/4 on the gauges when in traffic or the ac is on, note that temp is steady at half on the gauge on highway speeds, thanks for the video, it gave some odeas to try,,, cheers
hi friend how many liters of coolant radiator takes,i had oil mix with water in lr3 land rover ,iam thinking it clogged i tried haed to clean it but it still takes only 2liter of water,thanks

Great tips, after the draining test, I have seen people just changing it without testing

@@shaddapforever Glad we found the issues. Hope this helps others with the same problem. ✌
Did the radiator do the trick? My 03 Silverado engine gets hot with AC on
@@PFCYANEZ92 Yes it did. I purchased a new one and it stopped all that heating up. Runs perfect now. Good luck.
Most likely your radiator fan

Came to this video with my 01 civic, if I’m changing the water pump I have to change the head gasket too😂
I hope you still have your new edge cuz maybe you can help me with mine😅

This is exactly what my Honda accord is doing.
2006 Acura MDX overheats when idle my coolant reservoir was completely empty i put coolant in it same problem
Thank you very useful good information I appreciate it

That’s a blown head gasket
What was the issue?!

same issue what was ur solution?

Change coolant sensor

i’m having a major coolant leak, but not sure where. It’s literally pouring out the bottom of my car…
Idk if you figured it out now but check your water pump. That'd be the first thing I check if my car was dumping coolant but I couldn't see where.
Same here. Weirdly enough, my car has not overheated yet and the only sign is that the heater in my car takes a while to heat up.
@@wewhoareabouttodiesaluteyo9303 check your heater hose
Any idea how to resolve overheat only when AC is on after 30 to 1 hr ?
Hi, is water still circulation if thermostat fault?

This is for all vehicle
OVERHEATING REASONS COULD BE TEN OR MORE REASONS
100% true like a clogged water jacket in the motor.
