ksig181 Posted August 9, 2003 Share Posted August 9, 2003 So my I hace been without a car for the past month while the mechanics try to fix my car. It started off by over heating. There was a crack in the raditor, so they replaced that and the thermostat; and i thought the problem was fixed, but oh no. It over heats again, this time it is the cooling fan, specifcally the power steeing system, that was replaced. So to my dismay the car overheated one more time, but this time the mechanic does not find anything wrong, and says he can not make the car over heat. So i am picking up the car car today, but i want to know why my car overheats. If anyone has any suggestions it would be helpful.

poneyboy Posted August 10, 2003 Share Posted August 10, 2003 It sounds like you have the 93 like I do. I've been through the exact same thing as you - water pump, radiator, etc. etc. The overheating problem is intermittant. I haven't replaced anything in the power steering system yet, but supposedly there is an actuator switch that turns on the flow to the fan motor. (It's a hydraulic fan that runs from power steering fluid pressure) Ask your mechanic if he replaced that - it's the only thing in your power steering system that should be considered when related to your cooling system. I wish I could help you, but I'm beginning to come to a conclusion: if fixing the power steering actuator and heat temperature switch doesn't help, then this car is destined to overheat! It seems that it was inherently designed with a poor cooling system. This is certainly why they went to the standard electric motor the following year! Perhaps there's a mod that will allow for an electric fan motor? Quote Link to comment Share on other sites More sharing options...
SKperformance Posted August 10, 2003 Share Posted August 10, 2003 the 94 year also had a hydralic fan as well as other years and in there cars it seems to work great but it is an aluminum engine rather than a steel one Quote Link to comment Share on other sites More sharing options...
ksig181 Posted August 10, 2003 Author Share Posted August 10, 2003 thanx poneyboy for the information, i am feed up with the mechanic i am using, i went to pick up my car and they left the partly door open all night and drained my battery, they said the would place it on a charger and let it warm up, but the lazy bleep did not do it, and just jumped when i came to pick it up again. I am going to another mechanic that is a family friend, that i just found out about, and see what they can do for the car. Sam Quote Link to comment Share on other sites More sharing options...
ksig181 Posted August 13, 2003 Author Share Posted August 13, 2003 don't quite know what to make of this? But the car no longer is having problems i did not get it to the shop b/c i have been sick for the past 4 days, but it is running fine, it is mind boggling. And i do know this will come back to haunt me, but what should i worry i have a warrenty on everything, and they will give me a loaner car Quote Link to comment Share on other sites More sharing options...
NeiLtYmE Posted August 13, 2003 Share Posted August 13, 2003 wierd.... maybe your gauges are fried.... the temp sensor may not be working right Quote Link to comment Share on other sites More sharing options...
DJamal Posted September 9, 2003 Share Posted September 9, 2003 I have a 93 ES and had a prolbem overheating becuse of the hrdralic fan not work the way it should. I took the power streeing hrdralic contolded fan off and put an electric fan form a chevy Camaro on it. I used a after market tempture switch and relay. It been on the car for three years with no prolbem. Djamal Quote Link to comment Share on other sites More sharing options...
SKperformance Posted September 9, 2003 Share Posted September 9, 2003 one solution is to remove the thermostast which is a realhalf assed way to get around it but it seemed to work from a post i saw one thing to ask also is it happening when in stop and go city driving ? and also when it is overheating is the fan running at full speed at the same time?

ksig181 Posted September 10, 2003 Author Share Posted September 10, 2003 it mainly happens when i drive on the freeway approx 65 mph, hten exit and do stop and go traffic. Quote Link to comment Share on other sites More sharing options...
Thi Posted September 10, 2003 Share Posted September 10, 2003 There are some other causes for overheating such as clog/restricted exhaust system (car's been in flood), head gasket, fan clutch, bad timing. Good luck with your finding. Quote Link to comment Share on other sites More sharing options...
SKperformance Posted September 10, 2003 Share Posted September 10, 2003 i would say it is more to do with the fan then as the highway driving raises the temp to about 12000 degrees for exhaust gases hile driving is about 8000 so once you get off and there is no more air flow the car will over heat if the fan is not working properly you should check the actuator for the fan speed Quote Link to comment Share on other sites More sharing options...
