I will get staright to it. My temp gauge keeps going down when im driving for a long time and when im slowing down or stopped then it slowly goes back up to mid but never really stays there. Another thing I noticed that is when the colder the gauge the higher the rpm idles. It never passes more than 1k though. Please help! ive tried everything i know.


Yes Ive bleed the whole system for like a 45mins. like ten times.

Yes Ive checked the forum and couldnt find anything.

Ive checked both the ECT sensor and sender but wires arent broken.

But i must admit that im not to great with diagnosing electrical issue but Im willing to learn.

Once again please help!!!!!!!!!!

 

Clogged radiator? Changed thermostat?

 

Yes i changed the thermostat before winter.

 

Sorry. Didn't read that in your list. What about the rad? Fan working? Temp switch? Just throwing stuff out there now.

 

Well before i bought the car it looks like the rad was replaced because it looks brand new. The fan works fine..........temp switch? Is the temp switch near the fan and how can you check the radiator if is clogged? Btw the radiator hoses are at correct temp. Check with a temp gauge gun reader

 

Is the coolant flowing?

 

What do you mean? Yes i think so. When i squeezed both the upper and lower radiator hoses and it seemed hot enough

 

Help!

 

Man i have the same problem with mine but i have a check engine light on for my iacv it might be that. I havent changed it yet but i do have the problems you say my heat dosent build up and when it does i gun it and all of it heat leaves and my temp go's down . It never over heats for me but when i drive it for while my rpms just sputter between 1000 to 2000 .

 

Check your iacv . Cause i bleed the hell out of my em1 and still the heat builds up but when it gets cold outside the temp gauge drops

Hope this helps a lil

 

No CEL for me but ill check into that. My car doesnt over heat either

 

my car does the same **** but is fine in the summer n the heat is hot as hell during the winter hits vtec
