Question about 1994 Mitsubishi Diamante
I was wondering if anyone could tell me how to get the air out of the cooling system??????
Make sure the engine is cold and and remove the radiator cap. Top off the radiator and coolant recovery tank. Put the cap on the recovery tank but leave the radiator cap off. Start the engine. Monitor the temp. gauge about every 20 seconds. Carefully grab the upper radiator hose in 90 second intervals and very gently squeeze it a few times to help release the trapped air.The coolant level should drop visibly into the radiator as the thermostat opens. Now bring the rpm up to about 1800 and HOLD it there while you top off the system and then tighten down the radiator cap completely before you drop the engine rpm. I recommend using a friend to help with this procedure. Then let the car run as you check for the upper hose to feel warm and solid to the touch. Watch the gauge. The reading should be steady. If it starts to overheat, shut off the engine and wait for it to cool down. Repeat the procedure if necessary
