Question about 1996 Ford Explorer
I just recently replaced the head gaskets on my Explorer (4.0L V6). The engine is running fine; however, I am experiencing fluctuating temperatures ONLY when I have the heater on (just past middle to the ''C'' notch. With the heater off, the temp gauge stays in the normal operating range.
I hear a ''gurgling'' sound coming from the heater core especially on turns , which leads me to believe there is air in the system (in the heater core).
I cannot burp the cooling system with the radiator cap off and the heater on - it will shoot out coolant. With the heater off, the coolant will not shoot out and I can top it off with coolant.
I checked the pass. side floor board for any wetness, and I cannot detect any. However, I can smell a faint coolant smell when I first start it up but goes away after it warms up.
I lose coolant with the heater on after a 50 mile drive but after a 50 mile drive without the heater on, the level stays the same. I cannot detect any leaks underneath the car.
I am unfamiliar with a leaking heater core cause air to be sucked in to the cooling system, but is that possible? BTW, the heater control valve is brand new.
Have the system pressure checked. This is simple and quick. Puts the system under pressure and helps to locate leaks. Check cap too. System needs to maintain pressure.
Some engines have a "Bleed" valve in the head so you can force the air out of the system as you fill it with coolant. May want to chekc to see if yours has one.
\Fluxing gage indicates coolant sometime there and sometimes not. Low level. Sound says the same thing.
