Rear Heater Question

[sseaman]

Does coolant flow to the rear heater even when it is not on? If so is the amount different when on and off? im trying to figure out why sometimes i use more coolant than others btw i am planning some coolant system pm soon.

thanks

I think there is a valve that switches the flow on and off. (back of the motor by/on the firewall?)

okay thanks, it seems to use more when i run the heat i think ???

the valve flows to both heaters, so off and on for both at the same time.

What coolant system PM are you doing?

Keep in mind to continue the use of same coolant, or COMPLETELY flush the system (not easy or quick).

Are you replacing any hoses?

i have a slight leak on the water pump, so while i am at it i am replacing the 2 leaking hoses, and the the other leading off the water pump, and new belts. Would it be worth while to replace the idler pulleys?

any thoughts on the idler pulleys?
