Re: lc prado overheat cause?
The turbo will not cause overheating. Check the thermostat in the cooling system is working and then smell the coolant with the engine running. If you smell exhaust gases in the coolant it could be the head gasket.

Have you had problems with the vehicle not starting at times as well?.......if so and it is a GMC product then from my experience it was the key-switch harness cable $50 will buy you on on ebay...or pay $200 at GM.....mine did the same thing and also would not change gears...started driving in 2nd or 3rd gear.....as this is the cause as well....good luck....everything was fixed with mine..1..gauges not working 2 pressing hard on the key switch to start and when it did could only drive in 2nd or 3rd gear......
well 82000 miles is not a bad thing make sure it has always had a routine inspections and regular
oil changes brakes ect. i have a jeep grand wagoneer with 156000 miles on it im the 3rd owner
and it runs great its not always the miles. its how good they took care of it
What is happening to you is worn out sincronizers in you transmission. They are used to mesh the gears between shifts. They are made of brass and wear out easily on the 2nd gen cars. It grinds normally going into 2nd gear and into 3rd if its really worn. If you want a stronger transmission buy the 93 and up 3rd gen tranny. It is an upgraded transmission with dual sincros. Yours does need rebuilt. Or you can find one on the MR2 board for a good price used. I prchased a 93 trans for $1000. An older one will be about 200. Also it depends if its turbo, lsd or not. Good luck!
Sounds like the transmission has reached the end of service life. I have a 93 that did the same thing. It would drive until the transmission heated up then nothing, except for reverse. I had a TRW rebuild transmission installed and now my 93 Legacy has 500,000 miles. $2,200 to repair vs $25,000 to replace. The only thing you would miss is the new car smell for a few weeks. But you can keep $20,000 plus.
being 93' im not sure if the car has high miles, if it has 100k or more it would not surprised me if you start to get a poor performance and harsh noise comming out of the turbo. Life expectancy on the turbos usually run 100k and water cool tend to last a bit longer, some has better luck than other; than again it depend how the car has been driven, if it driven hard the turbos tend to work extra hard and burn out quicker. The most important factor now is that you have to maintain good clean oil change on regular basis and it very essential to cool and lubricate the tubo bearing. Bearing inside the housing usually tend to fail first, which will cause the turbo to spin unbalance wobbling in it housing causing it to make weird noise. I would take it to mechanic who know about the turbos, he can actuallylisten to it and tell you if the turbo is reaching the end of its life. turbo tend to get expensive to replace without it the car run very poorly and use excessive fuel consumption. If the turbo is reaching end of it life you can adjust the wast gate on the turbo to make the turbo not to run so hard, it will have some effect on performance however it will keep your turbo last allot longer than having it quit completely. Junk yard or ebay will be a good place to find a used turbo for cheap. hope that help some...
I had this problem with my 2004 turbo, I took it to my dealers and they said they it would need a whole new PCM unit as the disk drive was also faulty, happily they replaced it under warranty and didnt charge me a thing.
check the piping from the compressor outlet to the throttlebody for boost leaks. also check to make sure that the wastegate actuator is functioning properly. it may be stuck open. the other thing to check for would be an exhaust leak either between the head and the exhaust manifold or the exhaust manifold and the turbo.
if its none of those things, check the blades on the turbo (compessor and turbine sides) for damage and make sure that it turns freely
