Question about 1995 Toyota Camry

2 Answers

The electronic cooling fans are not running and the engine is overheating. What needs to be done to correct this? The engine temp gauge is working. The engine will not overheat if the heater is on and fan on high. There are no leaks in the cooling system.

    I understand the electronic cooling fan relay (s) may need to be replaced, however the owners manual doesn't indicate where they are located under the hood also, since there are 2 relays are there two turn-on relays? If there are two relays, can they be tested?

The cooling fans are controlled by a thermostat - if the fans aren't functioning this is the obvious cause, it's faulty. It's easy to test - just run the engine to hot and test if it has shut (resistance will be 0).

If the thermostat is ok then the only thing left is the fan itself - replace it.

    This response doesn't make sense.



    If the thermostat, (location?) is working, you say to replace the fan, however...there are two electric cooling fans on my 1995 Toyota Camry. Are suggesting both fans are malfunctioning and need to be replaced? Wouldn't I need to check the fuse or relay first before replacing a fan? Which brings me back to my original questions with you regarding the relay(s).



    With regard to the "the thermostat", if the temp gauge on the control panel is working, is there a need to check a thermostat and again, in a 1995 Toyota Camry, where is the thermostat for the 2 cooling fans located?



  • Azrael SRL Jul 09, 2010

    I thought that you already checked the fuse and the relays, this is basic stuff that everyone knows.



    The thermostat is basically a thermal controlled switch that , when the temperature of the water goes over 95 deg C, makes a contact that activates the relays that powers the fans. It's located at the base of the radiator - easy to spot, it has some electrical wires attached to it.. As i said it's highly unlikely that both fans would fail in the same moment - most likely your problem lies in a faulty thermostat. 
    The temperature gauge has nothing to do with the thermostat, different sensor of different type and in completely different location - top of the head, and connected thru a completely different wiring.

If the cooling fans aren't kicking on - chances are good the fan turn-on relay has failed.
The relay is under-hood in the fusebox.
Location should be marked on the lid of the box.

Thanks!!

    Where is the fan turn on relay located and can this relay be tested? The owners manual does not indicate which of the relays control the two electronic cooling fans.

  • jeffreykobas Jul 08, 2010

    Can you be more specific as to the exact location of the electronic cooling fan turn-on relay (s)? There are two fans, are there two relays?

2007 ford five hundred starts to over heat could it be the coolant temp senor


Is the vehicle overheating or is the gauge in the instrument cluster just showing it is overheating ? What's the temp. of the engine ? Using a infrared temp gun point at the upper radiator hose at the engine . At 223 degress the computer should turn on the cooling fan's , or another way to tell would be to hook up a professional scan tool a view coolant temp sensor data , what temp is the PCM seeing . Do the cooling fans come on ? Is the check engine light on ? Probably would be if the coolant temp. sensor was bad ! Testing to find the problem is the correct way to a fix , not guessing ! The electronics on your vehicle are very complex , computer controlled . Your best bet would be to take it to a qualified repair shop .

Radiator fans not coming on. replaced thermostat and cooling sensor


Hi Bill, is the engine actually getting hot enough for the fans to come on? if the engine does have overheating problem (but you say the temp gauge reads normal) then i would check the operation of the engine temp switch, there are two, one for the gauge and one for the fans.

I have a 96 Buick skylark.its overheating and I just replaced the thermostat and hose that runs from the radiator to the engine. But its still over heating.what can it be?


Bad water pump, blown head gasket, Clogged radiator, inside and out. If you constantly add coolant, head gasket. If not look to the radiator and pump.

My engine overheating problem is in my 2000 land rover. The fan is running and the electric fan comes on at correct engine temperature. After start up the engine runs normal the temp gage rises slowly to...


the usual suspects are:
stuck shut thermostat
clogged raiator
dead water pump
low coolant level
it's sunday, rovers don't work on sunday.
Then again, maybe its wednesday, rovers take half a day then. 25322555-21syibu3fgwpdxocjnkpw0ib-5-0.jpg

Why is our 2010 cobalt still overheating after changing the thermostat?it has the 2.2 engine.the temp reaches 210 +degrees.sitting idled and the cooling fan is not turning on.The cooling fan only runs


was the thermostat installed the correct way round . Fans should start spinning at around 75degres c. Check coolant temperature sensor ( not temp. gauge sender unit) for operation. Have a flow test done on the radiator to check for blocked cores.. Have a compression test done to check gasket and for cracks.

Engine Overheating and fluctuating temp gauge??!!!


Sounds like you have a leaking engine head gasket.

3.1 coolent fans will not come on replaced thermostat and temp sensor fans still want come on is there another temp sensor on the radiator which side


No,it sounds like you have taken the correct steps here.these 3.1 engines run a little hot, the fans will not come on until the temp reachs over three quater the way on the gauge, they are also prone to a bad temp sender, this is located on the rear head near the trany, but if its overheating and you have bleed the system then theres a problem, when i say overheating i mean the gauge goes to hot and coolant boils over and out the resivior, if this is the case then the next thing would be to have a block test done, these engine are also known for headgasket problems, this is when exhaust enters the cooling system and stops the flow causing it to overheat, a quick test to see if the fans are operating correctly and the relay also is to start the engine and then disconnect the coolant temp sensor and fans should run, if the fans turn on then have the test done, this test is done by draining coolant down a little then theres a tube that holds the fluid that sits on radiator where the cap is and if exhaust is entering then the fluid will turn yellow and this means a head or gasket problem.good day.

Temp. gauge not working after having a heater core replaced.


if the engine cooling system was not filled and air bleed out the system may have an air pocket and this keeps the gauge from reading correctly.
