The fan is meant to cool the radiator even after the car has turned off. Some vehicles have a heat type sensor to activate when the fan should "kick" in, others just automatically intermittantly run for a few minutes when turned on or have a set time for after it's turned off. Maybe when you did the wiring you inadvertantly disconnected something necessary to the start up of the vehicle. Sounds like you installed the fan to work properly so I would just concentrate on what wiring you were near when you put it in...something simple might've come off or loose.


I found the problem to be a poorly connected ground. After cleaning the plug the housed the ground; my problem was solved.

Greatestmind weighing in on this. Now it seems like you are saying your fan works fine but the coolant still overheats. If this is the case check your thermostat, and hope your water pump is working properly. Feel the inlet and outlet hoses on your radiator after about 5 minutes of engine running, both should feel hot to the hand.

How do you unplug radiator plug?

If you mean a freeze plug, that is usually in the engine block, not in the radiator. Maybe you mean a clogged radiator. If that is the case. First you would flush it out with water. You can remove the hose from the bottom. Then reattach the hose and add water and a chemical radiator flush product that you can buy from the auto supply store. Drive for about an hour of more. Then flush out the radiator again. Refill the radiator with water and see if your engine runs cool enough. If all that does still does not work go to a radiator shop and have them rod it out. If they can't do that, you may have to put in a new radiator. Good luck. One more thing. You may also want to check the thermostat.

Will a radiator for an automatic transmission work on a vehicle with manual transmission?

Generally no because the one for the automatic has a trans cooler built into it. I would have to disagree as long as everything is the same the radiator will work. And you do not have to plug up the transmission fittings on the radiator because it is just an in and an out. If you hook nothing to it, nothing will come out the other side.

How does an automotive radiator reservoir work?

A hot radiator releases excess coolant through the spring-loaded cap in to the reservoir, and when cooled the partial vacuum created by cooled radiator pulls it back in. A reservoir should be only about 1/4 full cold on a system that uses a radiator cap, some cars have a pressurized cap on reservoir and no cap on radiator

Has anyone heard of putting an eggwithout its shell in a radiator to stop a leak?

Yes, that is a very old temporary fix for a radiator with a slight leak. Although it has been shown to actually work, I would not recommend it. If you have a leak, have it repaired and do not use any type stop leak. They are for emergency use only! * The egg has the potential to clog parts of the radiator, reducing it's effectiveness. As said above, the egg is for EMERGENCY and SHORT TERM use only.
