Engine gets hot and blows out coolant at the coolant tank. The fan will not run when engine is hot. The fan motor, wiring, relay, coolant censor, and computer all checked good. Thermostat replaced. My Saturn is a 1994 SC2 strait drive. Please help.

    I would check the fan motor again. run some jumper wires to the fan plug to provide power and ground. jump the relay terminals, a bad relay could still "click" but not provide contact.

Has it ever been ran with no coolant in it too the point of extreme over heating? Could be a cracked er if it was head, cracks in the valve seats. have you checked it with a radiator pressure tester? Wonder if after purchased new, if the head and other parts were retorgued by service department. Probably an issue that would be hard to validate. How about the radiator fins and the also the airconditioning radiator in front of the engine radiator. May be full of road junk, like bugs, grass, leaves.

Try wiggling the connector to the fan and see if it helps.
Sometimes when you check things cold they test O.K., but once they get warmed up they change size and stop working.

You might run power directly to the fan to make sure it's functional

How do I know my cooling fans are working


There a a few tests you can conduct here. Firstly, put power directly to your fan(s) Run two new wires directly from the battery to the + and - of the fan motor. Be careful doing this, as there is a risk of shorting the battery to earth. Maybe connect up the fan end before touching the wires onto the battery terminals. This will prove if your fans actually work. They should spin up to speed. Next, test the fan thermostat. There should be a terminal connection somewhere. One side of the fan wires would be connected to the thermostat. You will likely need a voltmeter to do this test. The thermostat is just a switch that should operate after a certain temperature is reached. Normally you would have to remove the thermostat from the car engine to test it, but it might be possible to test it when it's still installed. Next, test or replace the radiator thermostat. If coolant is unable to flow through the radiator after the engine warms up, you will get overheating. After a short warmup period, the radiator thermostat should open and allow coolant to flow through the engine block. Next, when the engine is running, check the exhaust pipe for water. Some water might be normal, until the engine is hot, but if a lot of water is evident, then maybe the block has been cracked. Best test for that is a cylinder compression test, with a compression gauge. Lastly, please do something positive about this. There is a great danger you will crack the engine block, especially if you are adding cold water/coolant to a very hot engine. Remember: does the fan run off direct power? Is the fan thermostat switching correctly? Does the radiator thermostat work correctly? Is the water pump working correctly? Hope this helps. Regards,

Fans not working (overheating)


if you are losing coolant is it a bad radiator or just overheating or is it escaping into the engine pull the dipstick and look for water in the oil you will see water bubbles in it however the relay could have a short in the wiring at some point check with a test light for power rusty connections well ?

Coolant fan not turning and air conditioner blows out hot air.


Re-check the relay to make sure it's still good, then check the fan by hot wiring it to the battery. Also check the temp sensor on the engine. If the check light is on, don't drive it 'till you find out why or you can damage the engine.

Coolant fan not coming on, change motor, relay, censor & fuse sti


if the fans are not broken, here is a way to check them--- disconnect fans at wiring connection, then run a wire from positive on fans to positive post on battery,then run other side to ground if nessesary. if the fans are ok they will turn on. if not the coolant temp sensor is bad. or a short in wiring.
