gschloyale

iam gona try to bleed the cooling system... thanks.....

Hi every body.. I have a 1992 subaru loyale with a ea 82 mpfi engine, and a have a very strange problem. when i started my subaru, i heard a bubble noise coming from the heater, then when i pass the 3000 rpm the noise returns, finally when i stop the engine, a few seconds later i hear bubbles circulation. when i look the coolant reservoir, there are bubbles coming from the radiator. the first thing i think, is the posibility of a head gasket blowing, but there isnt bubbles in the radiator when the engine is running. i replaced the thermostat and the coolant but the problem persists. Any ideas???? maybe air in to the circuit, or cavitation of the water pump??? greetings
