I have a 91 toyota 4runner and I think my headgasket is blown. I would like to try other things before assuming that is the problem. THere is no water in the oil and there are some weird electrical pr

THere was no water in the radiator . There was plenty of oil in it. THe thing runs very ruff clug clug clug.when started and I can hear some sort of fan motor come on under the console or passenger side under the seat area. THese may not go together they are just observations. I tryed to take it around the block and it barely accelerated unitl i turned the heater on.,,,as soon as it got hot I parked it and turned it off. As far as I know the guy I got it from had no signs of overheating before a sudden overheating while driving up hill...thats all I got THanks so much

In the past there was a compain from the dealer about bad head gasket they had to replace both head gaskets with updated gaskets does the engine run rough for a few sometime smooth out? if so the gaskets are blown you need updated gaskets.is there alot of steam coming from the exhaust? another sign of blown head gaskets. how many times do you need to fill the radiator? you can also pull spark plugs from each cylinder and find the cleanist plug in that cylinder thats also a sign of blown head gasket in the area of the cylinder head all fluid goes out the tail pipe thats why you have to fill the radiator

SOURCE: 1993 Toyota Camry V6: Engine Overheating Prob

Yes if it hydraulically operated it could be because the pump for the fan is bad. If I am not mistaken the fan is run off of the power steering pump correct. check and make sure the pump is working correctly. I have not seen a hydraulic motor on a car I know they put them on a lot of diesel trucks like humvees and some Chevy diesels but not on a car. Most are usually electrical. I know on humvees with a hydraulic fan they have a fan controller check this and make sure it is working right you can unplug the controller and the fan should stay ingaged and turn faster.

SOURCE: 1994 Toyota 4Runner Overheating

I had the same problem - my 95 4Runner would overheat in 4WD only, and coolant would bubble out and spill over.

The problem turned out to be with the rear heater tubes and the fan clutch - my mechanic bypassed the rear heater tubes and I have no more problems. Not exactly sure why this helped. To replace the rear heater tubes, it would've cost $325, but to bypass cost $75. Most people don't even really use the heat in the back seat.

The second part of the problem, and most important, was the fan clutch needed to be replaced. At low speeds, it wasn't kicking in when it should have been, only working at higher speeds. Once I replaced the fan clutch and the bypassed the rear heater tubes, all has been well.

Hope this helps!!

A couple of possible problems, low compression on one or more cylinders, possibly a burned valve, possible headgasket leaks, have the compression tested and checked for a headgasket leak, both of these conditions would cause a rough idle and then seem to run normally when warmed up.

91 Toyota 4runner stalling


Try to clean the Throttle body of your engine I believe you never did, Also check whether you have also Air Flow Meter which is situated on the Flex Intake Hose of the engine.If so remove it by disconnecting the connector and remove the 2 little screws. Take it in your hands and check the inside where on the one side you will see a small wire surely would be covered on dust. By means of carburettor Cleaner give it a blast after you remove the "O" ring first.Give it a try.

Hi I have a Toyota 4runner with 2.4 22r engine which i bought with a blown headgasket. Can anyone tell me if this is a common problem or if there is anything else i should check on the vehicle to be safe...


Man that's alot of miles. I would check the trans. for shure.
On the head gasket I would make sure that the block is worth rebuilding. You may be better off to get a used engine and trans combo for about the same money as getting someone to fix that one.

91 toyota 4x4 22re overheats on highway, but not at idle.


original issue sounded like thermostat but now that you have lost power i would have to say thermostat, blown head gasket, and warped head

to check thermostat find and remove place in pot of boiling water the see if it opens, then to ice water to check if closes.


the only way i know to check headgasket and head is to check oil and water. oil will have water in it, and water iw have oil in it
