Hi all,

I'm Keaton and I recently joined the forum after searching and not finding my specific problem. I have a 2000 Civic EX coupe with a D16Y8.

Occasionally (about 1 in 10 drives), the engine temp will start to climb steadily when the car is stopped and idling. I have to rev the engine and force coolant through to get it back down. This problem doesn't seem to be affected by use of the A/C or any other factor.

I replaced the cooling fan relay just to rule it out because it's easy and cheap. Also burped the cooling system to get rid of any air pockets. Did a pressure test and the system held pressure. I'm kinda thinking bad thermostat, but I wanted to see what else it might be before just blindly replacing parts.

 

When the needle rises are the fans still running?

 

Yes.

 

A blown head gasket would cause that wouldn't it? That or your water pump is going out. Could be wrong though I'm not the smartest guy.

 

The water pump was replaced less than a year ago with the timing belt. There isn't any oil in the coolant or vice-versa. No smoke from the exhaust either. I suppose I could do the turkey baster test, but I don't really see the head gasket being the problem.
