Car overheats when driven for about 20-30 minutes. Have replaced radiator, water pump, timing belt, thermostat, radiator cap. There is a crack in the manifold, and at times the motor for the ac won’t come on and then will randomly kick back on. The heater runs really hot as well. I’m thinking the ac…

Look thru the grill to see if the condenser has debris covering it. If it does, use a shop vac with a brush to remove it as it’s easier than trying clean it from behind. If the condenser looks fine, when the engine is cold, remove the radiator cap. Start the engine, and as the engine idles watch …

Have you checked to see if the electric cooling fan turns on? If it doesn’t the car will overheat in traffic but may be fine on the highway.

The engine in this Honda is great, the head gasket is not. Very typical to have overheating as a symptom of a bad head gasket with this era engine. If you get it checked and fixed quick enough you will get a lot more miles out of this.

Yes we checked and the fan does turn on. Its odd because at times the vehicle won’t overheat until once we get off the hwy and are in city traffic, other times it starts to overheat while still on the hwy. Definitely has us confused

The problem has been ongoing for a few months now with us repeatedly fixing more and more parts, I’m hoping that if it is the heads we can still fix it and there isn’t lasting damage from how long of a process it has been identifying the problem. I’m wondering at this point if it would be a better i…

Have you tried what Mr. Tester posted ? He is one of the people who post here that gives excellent advice .

Not yet I get home from work in a couple of hours and I’m going to give it a shot as soon as I do. It is definitely excellent advice. If it is a head gasket issue hopefully too much damage hasn’t been done with how long the problem has been occuring to replace and save the motor

@Tester removed the radiator cap and turned the car on, large bubbles slowing forming one at a time rising and popping causing the level of the fluid to fluctuate. About 4-5 rows of fins on my condensor are flattened

Well? You messed around with the cooling system. So there might be air still trapped in the cooling system. Drive the vehicle around the neighborhood until comes up to operating temperature and redo the test. If bubbles appear in the cooling system again? That’s a pucker factor of ten. Tester
