the small tube behind the thermostat, if that pipe, does not flow at all times, the thermostat fails on j18 or J20 engines.
its a very very odd design this method. (same with heater core blocked,) if the core blocks then the bypass line must not be blocked, or bam.
thermostat, goes nuts.
I don't think that pipe is totally clogged, heater still works....I could not make the coolant temp steady, it would over cool going down a long grade. Moving the thermostat to the top hose solved all problems. Thanks for your reply!
