Hello,
New to the forum...I have a 1992 Cutlass Supreme, 3.1 engine. Recently the heater hose broke (corroded). I purchased a new hose and installed without any problems. Followed mdirections from car manual to fill/replace coolant....heater works for a while then it gets cold...engine overheats....wating for a while for engine to cool, repeat process but still same results. What am I doing wrong? Is the a specific way to replace the coolant?
Regards,
Ric.
