Therefore, the fan clutch is bad and should be replaced... I don't remember if I said or thought this in the beginning, or if I just thought you had checked it. Anyhow, change it and you're done!!!
Bypass heat control valve, and if this work's,replace control valve.

Engine does not heat up. I think thermostat is bad but can't find the location. It is not located a the engine block where the top radiator hose is connected to the engine block. It is a 1996 Toyota Rav4 (2wd)


Its on the front of the engine block under the alternator. Follow the lower radiator hose til it meets with the block, you have to take that hose off of the block and the thermostat is inside mounted to the block. When you replace you'll want to repl ... 1996 Toyota RAV4

My 1997 Geo Prizm engine is overheating and the heat is not working. I noticed the heat problem first, then the engine overheated the next time I drove it. Already added antifreeze (the reservoir was empty) then drove it around the block a few times. Engine did not overheat, but cold air was still coming out of the vents. Did I just not drive it for long enough, or is there some other problem?

1996 chevy corsica 2.2 liter engine. Coolant temp never reaches above one-quarter hot, therefore no heat. I've put in four thermostats, installed new radiator, disconnected the cooling fan, still no heat. Am I correct in installing the thermostat with the spring facing inward towards the engine block? What else could be the problem?


You may have a stopped-up heater core. It's a little radiator inside your dash; it's where the heat comes from. I don't understand why the temp gauge isn't reading any higher than that... ... 1990 Chevrolet Corsica

I have flushed heater core, replaced coolant temperature gauage,replaced thermostat, water pump, timing belt, flushed engine block, and radiator. Got a lot of brown sludge out of heater core and radiator. All is clean now and still using G012 coolant. Only get heat in Econ mode, no heat at all in Auto mode. I pressed recirc and econ and the only code shows up is 513 which is engine temp is too low and air control module is not correct. But I have resolved both of these. Pressing fan down,cold b

Only thing left that could cause overheating of my 97' Chevy Cavalier is the engine block restricting flow and boiling the coolant because i now have a new pump, thermostat(put heat to it and it works at proper temp) flushed the radiator and hoses checked everything else up to the block and all passageways are clear so the only thing left thats possible is the passageways through the engine itself. just not entirely sure how(apprears to have a fairly new head) and my dad bought the car in florid

I have a Chevy Venture 2001 that has serious problems with the engine overheating. I already replaced the thermostat & antifreeze. When I drive it just a block, the needle on the heat dial jumps from cold to hot. Then when I stop the car it jumps back to cold. I suspect it's the water pump that doesn't work, because sometimes when I take the cap off the radiator it appears the water is moving, and other times I take the cap off & it it's not moving. Also when turning on the heat the heat blows c

Overheated motor I had replaced piston rings and piston bearings and had the head skimmed and valves seated after over heating but the problem is when the engine is cooled down, the radiator hoses sqeeze closed as if there is a vacuum in the radiator. The temperature is normal on short distance and the starting is no problem although I lose about 100 - 200ml of radiator water.The engine had no piston ridge so was not needed to rebore. could the block or head be cracked as this was not checked?

My 1995 Lumina is overheating all the time can only drive it a few blocks before heat gauge goes to the right all the way and hot light comes on. Had thermostat replaced and it seemed to help..for a couple of days, then problem re-occured. Engine fans are not coming on so we replaced the fuses...no help there. It is not loosing coolant as radiator is full and coolant tank is also full. Also the internal car heater does not produce any heat at all. Could a bad head gasket be causing all of t

I recently changed the thermostat because it was overheating. It worked fine for a few weeks, now the temperature is fluctuating all over the place. What's strange is the engine will be hot and I'll have no heat in the car, but when the gauge comes back down to the normal level I'll have heat, and vice versa. There's coolant in the reservoir. I'm not sure if the new thermostat is defective or if there a problem with the water pump or if it's a partially blocked heater core. What do you think it

My 2001 Ford Focus ran out of gas last while heating up in my driveway. I put around 2 gallons of gas in the tank this morning and it turns over but the car will not crank. I changed the fuel filter and also checked to make sure the fuel pump is cutting on. After changing the filter the car still won't crank and I check the cutoff . I believe there isn't any gas getting to the engine block or coming thru the lines. I was thinking the sediment in the bottom of the tank is blocking the gas flow so

There is a warp on the cylinder head and block of my E46 2004 BMW 318i 4 cyl. engine. Is there a way to repair without machining? Like some gascket maker that can resist high heat.


Unfortunately, the correct and best way to approach a warped cylinder head is to measure the flatness of the head (head removed of course) and see if machining will not over exceed the flatness of the entire head to correct ... BMW 318
