akaralnick Posted July 6, 2015 Share Posted July 6, 2015 It's been in the 100's where I live and lately I've had to keep a close eye on my coolant levels because my ES250 has been sucking it all up and overheating. Has anyone had this problem? Quote Link to comment Share on other sites More sharing options...
lenore Posted July 6, 2015 Share Posted July 6, 2015 No, you have an issue on a older Lexus...first check and see if you have leaks, than possible a bad thermostat. Also check cooling fans to make sure they are working. At that point you may have a clogged radiator. we need more info from you. Quote Link to comment Share on other sites More sharing options...
gbhrps Posted July 15, 2015 Share Posted July 15, 2015 akaralnick, A 24 year old car. Ever had the coolant system flushed? The radiator cap pressure tested? The thermostat ever replaced? Quote Link to comment Share on other sites More sharing options...
boredazhell20 Posted July 17, 2015 Share Posted July 17, 2015 +1 for the suggestions above. Usually with overheating issues I would check the following: 1. electric fans kick on as stated above? 2. Did you have any engine codes pop up before the overheating occured? 3. Does the coolant levels drop? Any coolant in the reserve tank? 4. Headgaskets might be an issue. I will check for leaks and pressure test as stated above. 5. Thermostat might have failed shut. Check the thermostat (easy to access). 6. Worst case scenerio I've seen is that the wrong coolant was used or some quick fix coolant leak solution (which is crap) which cakes up and causes the cooling efficiency to go down dramatically.

coppens1 Posted November 28, 2022 Share Posted November 28, 2022 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.
