Having the fan run on for a bit after the engine has stopped is not abnormal in itself, but 20 minutes sounds excessive.
If the fan does eventually shut off, I'd consider changing the thermoswitch (this is a sensor screwed into the radiator somewhere near the bottom, with a pair of wires connected to it - to change it, you'll need to drain the cooling system).
If the fan stays on continuously until the battery is completely flat, see what happens when you unplug the wires from the thermoswitch. If this stops the fan, you need to replace the thermoswitch. If it doesn't, then you need to examine the wiring associated with the switch and the fan, looking for damaged insulation.

The fan runs on a temperature sensor and operates according to engine temperature.(even with the engine off).I would suggest this is faulty.To locate this trace the wires from the fan

I would venture to guess that, based on past experience, that the problem is more likely to be the thermo-switch in the radiator. Find what looks like a large plug in the lower part of the radiator it will have two electrical jacks. If you test this with a meter and there is continuity when cold, there lies the problem. If not then i would suspect a fused relay (pricier to buy). You would find it located just above the fuses... Hope this helps...;-)

Check the alternator out put.Also the alternator could have a bad voltage regulator,or diode gone out,would cause this problem.Out put should read 13.75 to14.25 .

there is a solid state fan relay located under the passenger side headlight assembly. There are two ways to get at it. Either you can tear apart the entire front of the vehicle or you can remove the passenger side headlamp assembly and carefully drill a hole about in the middle of the opening and down towards the ground. Look in the hole you drilled you should be able to see the relay. Continue drilling/cutting until you have a hole just large enough to get the old relay out and a new one in. The hole will be covered by the headlamp and has become the preferred method of replacing since they are so common and removing the entire front assembly is so time consuming.
