[quote="Mikeybdman"][quote="pjwinsd"]1992 lexus es300 approx 160K miles. Drove from San Diego to Murrieta, car sat for about 1.5 hours - drove one mile - car sat 30 minutes - drove approx 5 miles when car lost power/slowed down, then check engine light went on, seconds later all lights went on as car died. Coasted and stopped - steam coming out from both sides of hood. Lifted hood and most coming from melted T connector near overflow. Let it cool off for hours & T connector replaced, added water, burped, but still hot. Replaced thermostat but still hot. Please advise - my car is in Murrieta and I live and work in San Diego and need help - What next? Thanks![/Quote]
Does it overheat relaly fast, or does it slowy get hotter and hotter? If it is really fast, and the thermostat has been replaced, I would suspect a bad water pump, or an obstruction stopping water flow.
They make a flush'n fill kit from prestone that has adapters to install in the heater core hose that flushes the system. With the radiator hose disconnected at the thermostat, and the thermostat removed, when you apply water pressure to this adapter, you should get water flow from both directions. If one is not flowing, track down the obstruction. If the water flows both ways, I would suspect a bad water pump.
Make sure after servicing, you bleed the air from the system thru the bleed port.[/Quote]
