Hi, I have a 92 ES300 that is overheating. When this first started I took it to the mechanic and the radiator and water pump was replaced. Then my upper radiator hose had a leak so that too was replaced. When these items were replaced the temperature gauge never traveled very high, but it did rise a line or 2. After a while I had to check my water every 2 days. Again the mechanic recommended that I take the thermostat out and thought the motor on my cooling fan was going out so that was replaced. Ugggh, as of right now I can not drive more than 9 miles on the freeway because the temperature rises so fast. The last time I drove it there was white smoke that seemed to be following me. Just as a test I filled the radiator and reservoir and started the car. I left it on for about 10 minutes until it reached normal temperature. When the engine cooled I looked in the radiator and almost all the water was gone but there was no visible sign of a leak.

Frankly, I've taken it to a mechanic every time I've had a problem and that hasn't worked as of yet. I can't afford to take it to the dealer so I'm looking for some outside help. Does anyone have any suggestions as to what the problem could be? Any help is appreciated. Thanks!

if no visible leaks are around the block, radiator, water pump. Then more than likely your head gaskets are blown and are leaking into the combustion chambers causing the white smoke.

Hydralic fan.... Did you check the plug that connects to the top of your power steering pump? Very common problem when it comes to the older ES's. Just search the forums here, thays where I find all of my answers... =)

Although the white smoke will tend to indicate a blown head gasket, don't give-up yet.

Another possibility is that you have a large air pocket in your cooling system that will need to be "burped". This could have resulted from the last time that your system was drained and re-filled. Such an air pocket will cause your car to overheat and suck some of the coolant from the reservoir into the cooling system as some of the air is released, causing you to add more coolant without any leak being evident.

Hope all turns out well for you
