I was idleing one day in the cold weather. Heater "was" working fine then all the sudden it kinda fadded away and got cold. I was like wtf and drove it home. Before I even got home the temp gauge was getting really hot near the red so I pulled over let it cool down and then drove the rest of the way home. and the heat still did not work during the overheating, just cold air. Sounds like a water pump to me since the heat did not work. Can anyone please help me with this?? Thanks It's an 89 CRX HF 5-speed

 

try a new thermostat first...

 

Im sorry to tell you this, but this is your headgasket and you know what that means head gasket = $$$ unless you can do it yourself

 

check to see for leaks in the radiator. just replaced one on my accord with the same symptoms.

 

I replaced the Thermostat a couple weeks ago so it's new. Even if the head gasket was blown the heat should still work because the water is still flowing threw the head/heater core correct??

 

Also there are no leaks

 

when your heat goes, and your car is overheating, this means your head gasket hard to believe but im sorry

 

if it overheats when you get on the gas then it's a headgasket, and they only cost $23 at your local autozone

 

ha.... i have the exact same prob.... replaced thermostate a month ago. heat works for 2 weeks

then a week ago, nothing. no heat

so i changed the thermostate again today and wabam!! overheating plus no heat.

i hate my ****** car
