1992 Lexus ES 300 Repair Question
92 es300 overheating when not running on road
when car gets hot, turn engine off and disconnect fans, put hand on rad in several spots, if rad has cold spots then it needs replacing.
How would I know if it not the water pump or thermostat because it not leaking
What it does is when it get hot motor send antifreeze back to.the water resever and its star boiling in side of it
if the thermostat or wp was bad it would overheat allthe time.
I feel that the fan is running to slow and fan kick on whenever isometric drive is this is the way is suppost to work
How do I know if it a fan problem does it turn on and of even if the car is in normal temp
you have a sender to turn it on, when it oerheats it should there is also a relay, oneof htose could be bad. try replacing relay with known good one in underhood box. is fan getting power? check that too.
I change thermostat water pump and timing chane but it stillheats up my mechanical say is the power steering pump that that making the fan turn on when it supposition to
check the rad like i sltated in first response.
