Lexus Forum 261122 01 Lexus ES300 Overheating
Dear Lexus Forum, I have a Florida 01 Lexus ES300 , with only 95,000 miles which is losing coolant and Overheating. It has only 95,000 miles on it. I seldom drive it over 5 miles at a time. For some reason it usually runs at about 1/2 on the temp gauge, while my 98 Lexus ES300 runs at 1/8 or less and never overheats.
Once in a while it has overheated, so I have added water to the radiator. This year I have noticed I have to add water every 2 months, so I had a radiator flush done at Pep Boy's, thinking that the % of water vs anti freeze was too high, so it needed the flush with coolant replacement.
Today, I needed to charge the battery so I left it running in the driveway for an hour. When I got back the car had overheated and lost a lot of coolant.
I wonder if I need a new water pump, or thermostat, or maybe the radiator itself has gone bad. I don't understand why my 98 ES300 radiator has been trouble free for 20 years, while the 01 ES300 radiator has been a chronic problem.
Thanks in advance for your advice. JC
