Softly418 had this problem...........

This could result from a thermostat which is stuck closed (but you have a new one), or a failed coolant temp sensor not allowing the radiator fans to run when they should, but I think you have a blown head gasket. Overheating is a classic sign of combustion gases getting into the coolant. The pressure also forces it out of the overflow.

Warm up your engine a little, about half, and remove the radiator cap by putting a towel over it first. Then let the engine keep idling until hot while you look down the filler neck into the radiator......carefully.

If you see white bubbles like dry ice, that is a failed head gasket. If not, have a mechanic do a test for combustion gas in the coolant with a gadget like this

SOURCE: Camry overheating

Possible stuck thermostat(located front LH side below the alternator), or faulty water pump(inside timing cover)!! The fan has no connectors because its hydraulic driver through the power steering pump(V-6 models only). You may disconnect the switch on the powersteering pump to test the fan.....with the switch unplugged rev the motor to 2200RPM and you should hear the fan increase in speed. If not check the filter (LH side of the radiator) its black with rubber tubing on each side. Check also power steering fluid. Hopefully this helps!!

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.

My 94 Taurus is running hot I have already changed the water pump, thermostat, upper radiator hose, and radiator fan motor, any suggestions on wat it might b

Could be clogged up radiator. Does the fan motor kick on once gets hot? They have a relay that sometimes will go bad. Good mixture of coolant is important also, If just water, it could be boiling out the overflow once gets hot. Radiator Cap could be losing pressure causing to overheat. If none of those resolve issue, it could be internal leak which usually means head gasket

I drive a 1990 celica 185 gt4, it had an issue with blown head gasket ( pushing the water/coolent out expansion tank) got gasket done. head plained etc. i got car back from garage with head gasket done and...

im guessing that maybe your thermostat is sticking. im not sure what else would make your coolant rush out like that. if im right, then that would definitely make your car overheat at speed, but not at idle. that isassuming that the thermostat is at least partially open. if that doesnt fix the overheating, then u may want to consider checking the ignition timing for being too far advanced, or even the camshaft timing.

94 toyota camry xle v6 overheating noticed leak in overflow res.

I think the leakage out of the reservoir is being caused by the overheating, not the other way round.

This can be caused by several things:

- failed thermostat (not opening)
- failed temperature sensor (not turning on the fans)
- blown fuse or failed relays in fan supply (if electric)
- soft hose from radiator to water pump "sucking in" and preventing flow
- blown head gasket allowing combustion gas into the water jacket (less likely)

I HAVE A 93 TOYOTA CAMRY LE V6, THAT HAS A WATER PROBLEM, THE WATER KEEPS GETTING VERY HOT, ENGINE PUSHES THE WATER OUT TO THE COOLANT RESERVOIR, LEAVING MY RADIATOR DRY. I HAVE REPLACED THE THERMOSTAT AND...

These engines will overheat for many reasons. >>make sure there is no leaks at all, as air will cause the system to overheat while losing coolant at the same time. Depending if the radiator is original or after market, there may be TWO radiator caps (one on the engine and one on the radiator)- the one on the engine usually is faulty because of direct engine heat to the seal.>> On the thermostat housing, there is an O-ring at the end of the feeder pipe, usually leaks especially if the thermostat was replaced and not the O-ring. >>Check also the hydraulic driven radiator fan>>Check power steering fluid for proper levels first. unplug the switch atop the powersteering pump, start engine, rev to 2000 rpm (fan should increase in speed-you should hear it) if not it may be faulty.>> Check system for proper flow- With engine cold, remove the engine side radiator cap and rev the engine(1000rpm) slightly, notice if the coolant is flowing. If not, possible faulty pump, or clogged radiator. Hopefully this helps

91 toyota camry overheating problem

It doesn't overheat with the air off? It sounds like you aren't getting enough airflow thru the radiator. Radiator fans not working or leaves and dirt stuck in the radiator.

91 toyota camry overheating problem

So far you did the right things in the right order. If you have a pressure cap (looks like a radiator cap to the rear side of the engine. Dealer $15) change the pressure cap also and then flush the radiator. A sure sign of blockage is when you open the radiator look around inside the top if you see brown or green kind of gunky stuff. Flush the radiator anyway.
If after the radiator is flushed and you still overheat, the next posibility is the head gasket. But don,t worry yet, follow these steps and observations. (this goes for 93 camry V6 also, I have one)

  1. change radiator cap and pressure cap where applicable
  2. Change the thermostat.
  3. Some cars may have a thermo switch which ramps up the fan(double fan designs). Change that if applicable.
  4. flush the radiator and engine block
  5. change waterpump AND headgasket.
The temperature guage can tell you what you need to know.
  1. If the guage starts to spike up after stopping, pausing in traffic or while in gear not moving but it is fine while driving along the highway, then you are having a blockage in the cooling system. FLUSH SYSTEM.
  2. if there is a bubbling sound in the engine when you turn it off, FLUSH SYSTEM
  3. If the car overheats at anytime, anywhere and it drinks coolant like a fish, then you my friend have a headgasket problem. Change waterpump and head together

The cap on the coolent reservoir may not be maintaining the correct pressure. It could also be a faulty thermostat or a defective drivebelt, hope this helps
