Hey guys first timer. I got a 04 honda accord sedan 4cly. Over heating issues i changed the radiador, two busted hoses to the throttle body, n thrmostat. Still over heats and heater blows cold air. Idk if system has a air bubble some where or water pump going but water pump has no leaks or noise.

Also when i turn the ac on the whole car shakes like a bad 9.0 earth quake lol. Woundering if the motor mounts could be the issue.

Thank you.

Asap help. Thanks. Need this fixed mechanics cant find out dealers charge to much

 

did you burp the system after the new radiator it could be trapped air. does the heat stop blowing when you come to a stop then start blowing hot air while your driving ???. try this take the radiator cap of while the engine is cold then start the car and turn the heat on full blast let the car run while you watch and see if air bubbles start to come out of the radiator usually wait till the fan kicks on and fluid starts to overflow before putting the radiator cap back on.

 

Yea im doing that now. Ive seen a few bubbles come up now the radiator is full but for some reason now the fans aint kicking on. N i havnt been able to drive the car everytine i try to drive it its over heated from trying to let the air out and what not but im sitting here now car on seeing if. Oh well there it goes lol wow coincidence that it turned on. Welp lets see what happens from. Keep u updated thannk u for ur help

 

First bleed the coolant system. If there's air in the cooling system it's can greatly influence the coolants ability to cool down the engine.

After you bleed, if the problem still persists make sure your radiator fan is cycling on/off. "The fans seem to be running" - you need to be 100% that it's running. What your describing is common problems associated with a failed radiator fan. Let the car idle up to operating temperature and keep your eye on the temperature gauge, wait about 5-10 minutes after operating temperature is reached for the fan to on. If the car begins to overheat before the fan ever turns on shut the car off immediately and open the hood to let the heat out so nothing is left susceptible to heat soak.

You should also stop driving the car as much as possible until the problem is resolved, I see it a lot where people will continue to drive the car even though it overheats and it usually ends with them paying a lot more out of pocket to get a warped cylinder head that they caused fixed. Thinking of that, your symptoms are also related to a warped cylinder head or bad head gasket. Usually once that happens the only way to keep temperatures down is to keep moving and have the heater fan blowing at high speeds.
