pwade84 Posted October 26, 2010 Share Posted October 26, 2010 I have a 96 ES 300 that keeps overheating. I have changed the thermostat, water pump, and have within the last year, put in a new radiator. I have checked for leaks and have found none. There is an oil light that comes on below the temp guage and White smoke puffs from the oil dip stick when I remove it while the car is running. I'm at a loss and don't know what else to check, or change. Can someone please educate me on what else I should check? Quote Link to comment Share on other sites More sharing options...
lexis lexus Posted October 27, 2010 Share Posted October 27, 2010 pw, I feel for you. I've got similar probs on my '94. Overheats every 400-500 miles. When I drove it home the day I bought it in July, the seller had the dash lights turned off and I didn't realize it was burning up till I saw steam coming from the overflow. Filled it up w/ antifreeze, replaced the rad cap. Ran fine for the next few weeks, but then overheated again. I started carrying a jug of water around and watching carefully. The inside of the oil cap looked a bit milky, so I threw in a can of copper based stop leak. The oil cleared up. But overheated once again several weeks later. My radiator looked fairly new, so decided to replace the tstat while I was replacing the knock sensors. Then said, sh**, since I've already taken off the top of the engine, I'll just do the head gaskets. I just got through with the front bank, moving onto the rear. You hit many of the likely suspects -- radiator, water pump, thermostat. Try a new rad cap, cheap and easy. If that doesn't work, may need to go for the head gaskets, especially w/ wisps of white smoke which might suggest water in the oil (look for milky oil residue inside the oil cap). Good luck and keep us posted. LL Quote Link to comment Share on other sites More sharing options...
