Does the motor need to be at temp or cold when bleeding the cooling system. Common sense would say at temp, being the thermostate would need to be open, but working with hot coolant just doesn't seem like fun. I found the bleed screw, by where the top hose connects to the motor....

I figure to just run it and open this and see if any air come out. I am having idling issues, and this seems to be something everyone recommends to check...air in the cooling system..

 

open it at cold temp. and let it run thru, make sure to clean the mess 100% because if an animal gets to it.... bad news, it sucks all the moisture out of their body and kills them.... and u can get in a whole s**t load of trouble for it.... any ways whats the problem ur having???? what year make and model car do u have???? keep me in the NO.... good luck

 

OK, so I do it with the engine cold....

I have a '88 civic DX, but was told when I bought it that a different motor was installed. I found out last night how to look on the block to the right of the exhaust manifold and see what motor is in it now.

My problem is it wants to stall when I have the clutch pushed in and the engine is idling. Some suggestions have been IAC, altenator, and bleeding the coolant. I just have not had a chance to look at anything yet.

Don't just go adjusting the idle screw.

Try cleaning the IACV with some carb cleaner, and also check out the FITV (if you have one its on the bottom of the throttle body)
