Hi
I just recently bought ES300 96' . It had a new thermostat in the trunk. I found out after few days that car have a tendency to overheat. I took it to the PEP boys and they indeed recommended new thermostat. I changed it myself and ...still overheating. because this thermostat was from unknown source I decided to remove it completely to rule out one problem. Tested yesterday and it's still went hi on the gauge. I turned off and still added almost 1 gallon of antifreeze!. I decided to come back to PEP BOYS today for some more tests. After starting I drove for about 20 min (7 miles) with A/C on and it didn't went above normal range (gauge was right in the middle). They tested again. I suggested to check the fan, I felt that is not turning quick enough- you can stop it with your finger and it's not reacting on temperature raise or A/C on/off, just running with constant speed. PEP tech told me that the temp went higher that suppose to and the fan didn't "kick" into a higher gear and told me to replace hydraulic fan motor- 385$ quote from local toyota dealer. I went back home- temp stayed right in the middle all the way- and start researching for a better price on this motor (that's how I came across this forum :D ). Now I got a headache from all what I read- possible problems. After all I read it's most likely not a bad fan motor, more advices point at sensor... I don't know if I'm right. I checked water lvl few minutes ago, it's right under radiator cap but almost nothing left in the plastic tank.
Any suggestion what should I check before I spend too much money? At least PEP BOYS excluded water pump, they didn't found any leaks and they don't think it's a head gasket. And there is no thermostat installed at this moment. I live in FL, today morning was 85...
And also, any tips where to look for a cheaper parts?
