From a COLD (overnight) start , with the system closed(cap on) when you start it , can you feel pressure building (or bubbling) in the rad. hose almost immediately? If so , have tested for head gasket leak.
No i dont feel it
Define 'overheating' .......conditions and temp.(over 215F), position of guage needle (if equipped) while driving, but cools down at idle or the opposite , heats up at idle but runs normal at speeds above 40MPH.?
