When the engine is hot, the fan is supposed to run for a little while
after you remove the key. That's why you keep stuff out of the fan at
ALL TIMES, unless you've disconnected it or the battery.

Since you didn't say there was anything wrong with any hoses or belts,
there's probably a coolant leak. Common places are the water pump or
the plastic coolant hose fitting on the side of the engine, above the
transmission. Looks for crusty deposits there and around other places
where coolant hoses connect up.

Hopefully the coolant hasn't run so low that the engine seriously
overheated, warping the head. Assuming that it hasn't, the cooling
system needs flushed, the system pressure checked, leaks repaired and
refilled with the proper coolant. While it's all apart, if the hoses
have't been replaced before.

Could have been a problem with the head or gasket, but probably not. At
least not before it overheated.

Also check the fan belt. It connects the electrically driven fan on the
driver's side to the one on the passenger (US).

Where are you at? Want advice on a good mechanic?

to check for blown head gasket, look for signs of the water and oil
ixing - 'mayonaise' either under the filler cap or on the dipstick. also,
take to a garage and ask them to do a sniff test. this is basically putting
an exhaust emissions sensor into the cooland expansion tank. it will pick
up any exhaust fumes that have found their way thru into the cooling system.

could just be a cooland leak. fill it with water and put the cap on, then
run the engine and look carefully at all the water pipes for any signs of
leakage. you might also find theres white/green/blue crystals around one of
the joins which would indicate a leak. if you find a burst pipe, replace
it. if there is a leak from a join - pull it apart and clean it up then
refit it. run the engine again to check that the leak is fixed.

***never add cold water to a hot engine, as you risk warping the head***

when you've got it leak free, fill with water and add a cup of washing
powder (persil type stuff) and run it for a while (at least 30 minutes).
let it cool, then disconect the top hose from the radiator and flush it both
ways with a hose pipe until the water runs clear. drain and refil with
antifreeze.

 If it's a automatic may be trans cooler, if not maybe engine oil cooler if
there is one!
