I have a 91 lumina eurosport, 222,000 miles, with 3.1 engine. I recently had some engine work done and had intake manifold gasket replaced. The engine now runs noticeably hotter than before repair at both idle and at speed. At idle the temperature gauge continually goes almost to red area before fan kicks in and brings temperature down then fan kicks off and temperature rises again. At speed I am running noticeably hotter to. I have no external coolant leaks and do not appear to be losing any coolant. My thermostat appears to working ok and never had any engine overheating problems until recent intake manifold gasket repair. Any ideas what could be causing this condition?
have the same problem?
