over heating

Could be an air pocket in the cooling system, blown head gasket, inoperative radiator cooling fan or several other things. Best to have a technician diagnose this issue, and don't let it overheat any more or you wil damage the engine.

we would be happy to check it to find out the real problem, our basic diagnostics start at $40.00

I had the same problem, changed themostat, and radiator I started to change heads $$$$$, but only needed a new heating coil ( cooling system issue )....$180, but now I have other new parts so its OK.....hope this helps....1994 GS300 173,000mil
