when the search function is down, i guess there's bound to be a rise in stupid questions.

i've got a 96 b18b with a surging cold idle, and i'm needing to bleed the coolant after cleaning out my iacv and bypassing my fitv.

basically, how do you bleed the coolant system? as far as i can see, i have no bleeder valve, and i remember there being one on the thermostat housing on my mom's 96 teg.

fast help would be appreciated. i'm ready to solve this stupid problem.

 

Well, I guess a simple bleeding job would consist of:

1. Fill up the radiator with coolant/water until the top.
2. Start the car and have it run until the thermostat opens up.
3. When the level of the coolant mixture has dropped, fill it up more.
4. Cap off radiator.
5. Fill up reservior container until the mark on the side.

Is that what you were looking for? There are places where you can go where they will flush your coolant. But you need a machine for that, I believe.

 

this will remove all the air?

i figured this was the way to do it, i just wanted to be certain.

 

you can also squeeze the rad hoses (big ones, upper hose) to help push the air out.

 

sometimes there is a bleeder valve, follow the upper radiator hose to where it connects to the head, if there is a nipple lookin thingy there (technical term :-P) crack er open and it will bleed the air out of the system thru there.

Forgive my n00bness, but:

1) Do you leave the radiator uncapped when you run the car? (between steps 1 and 2)
2) How do you know when the thermostat has opened?

the lower rad hose will get hot and then eventaully the fan will kick on

Correct, also the level of the coolant in the radiator that you just filled will drop until you can't see it anymore. The coolant is now being pumped by the water pump through the motor/heater core. You will also see the temperature gauge go a little colder suddenly.

 

Cool, thanks guys!

 

hey shamoo should the heater be on when bleeding the system?
