Hi can any one tell me why the radiator keeps running on after i have turned the car off! its so annoying i have to take out the fuse to get it to stop then about two hours later if i go to put the fuse in it is still running! I dont thrash my car, its dumb.

A couple of possibilities. Since they probably disconnected the battery to replace the starter, they may have left a feed wire to the fuel pump circuit disconnected when putting it back together They may have accidentally grounded a circuit and blown a different fuse. You need to check fuel pump pressure to see if the pump is putting out enough pressure. The pump just may have just wore out and cannot feed the injectors. Air may have entered the fuel system and needs to be bled out.

You have either lost the "keep alive memory" 12 volt power feed to the radio that is always hot even with the key is turned off or you have a defective radio.

it maybe possible the radiator fans are not working,try the fuses.at idle you should hear the fans start up at idle when warm.

Its supposed to keep running even with the car turned off if the car is still to warm, they work off a sensor,, now if it keeps running way to long,, the sensor is bad,, ( if you have to pull the fuse to make it quit after a while,, then check the relay , and then the sensor )

Hi, If you see white smoke coming from tail pipe then you will know it is leaking through engine.
I would suggest after you replace head gasket, that you put new radiator fluid (50/50) mix and a new thermostat in. The fluid will keep it from boiling over. Good luck.

Sounds like your cooling fans on the radiator are not working. The fans are activated by a thermol switch on the engine or radiator reading the coolant temperature and an A/C switch. When the coolant is too hot the fans should activate cooling the system down. And, when the A/C is on the fans should also activate in order to cool the condensate so the A/C would work.

When you are driving, the movement of the vehicle throught he air is providing enough air flow to keep things cool and functional.

I would check the radiator fan fuse or fuses first. If those are OK I would try to run the fans with 12 volts and a ground that I supply just to see if the fan motor(s) actually run when powered. If the fan don't run when powered then the fans are bad and will need to be replaced. If the fans do run when you power them manually, then something is not allowing the power to activate, like a relay, control unit, or wiring.

It will take a little diagnostics, but it is not too difficult to chase it down.

If other techs have looked at it ,the common things have been checked. What sometimes is over looked is the space between the radiator and the A/C condensor. Debri gets stuck to the radiator and is hard to see . If you loosen the radiator mounts you can see between the two.If it is very dirty it might be necessary to remove the radiator to pressure wash it.

What has the radiator got to do with the fan coming on? There may be a bad fan switch,screwed into the radiator,but you wouldn't change the radiator,only the sw ,if bad. You could jump the fan sw wires,turn key on, to test for a bad sw and a working fan

thats normal
