In Reply to: remove heater core valve? posted by poe on January 14, 2001 at 17:25:58:
The valve is held to the firewall by two screws. Once you undo them, the valve is supported only by the hoses, and you can move it around so you can access the four screws securing the core.
An easy way to test the valve is to unplug its electrical connector. That is supposed to force maximum heat. If you don't get heat, and the engine is warm, chances are the valve is bad. Pray that's the problem, because it's a lot easier and cheaper than replacing the heater core.
How do you remove the heater core valve when you can't get to it becouse the brake fluid container is in the way?I can see the four screws that need to be removed but can only get to two of them.also how do you tell if the heater core valve is bad?
