2007 lexus es 350 overheating when under a load from a/c or when driving

Asked by GiftedHands28 Apr 30, 2021 at 05:43 PM about the 2007 Lexus ES 350 FWD

Question type: Maintenance & Repair

After sitting for about 2 hours with the vehicle running i noticed the needle
rising to the "H" when i began driving it cooled down but when i sat still it will
begin to get hot again. We just bought this car unfortunately at 236k miles
and were told its mostly highway miles which is fine. Could it be that water
was being used for a long period of time and destroyed the water pump
impellers i'm not sure what else it can be without taking it apart. i Don't think
its the thermostat and so far no signs of a blown head gasket also both fans
seems to be blowing but im not sure if they are blowing strong enough.

You should do a full cooling system service and perhaps replace the water pump too.

This is an airflow problem. When the vehicle is not moving air is not being forced through the radiator. Since it cools off when you start moving the water pump and thermostat are good. Make sure the radiator cooling fans are working correctly and the front of the radiator is not blocked by dirt, leaves, or other debris. Hope that helps! Jim
