Sounds like the fan relay is shot and needs to be replaced.

Cooling fan continues to run after engine shut off.


The fan runs for a short time, after ignition off, to continue to cool the hot engine.

Engine fan runs after car shut down


The most likely cause of this problem is a part called a "Fan switch".

http://www.tegger.com/hondafaq/misc/view_from_bottom.jpg

This link should be the location where yours is located. When it is working properly, it turns on the fans when the coolant reaches a certain tempeture.. In your case im assuming the switch is defective.. and stuck open.

How to change radiator 1998 oldmobile intrigue


Hope this helps you. Here are the basics. There are many problems you may run up against (frozen bolts, stubborn or cracked hoses, rusted clamps, etc)that may need to be fixed or replaced before proceeding: SHut off engine, allow to cool completely. Disconnect the cooling fan, remove negative battery terminal connection. Drain radiator by opening draincock and/or removing lower radiator hose, collecting coolant in a drain pan. Do not let it go onto the ground - bad for environment! Open top radiator hose to allow remainder of coolant to flow out. A few quarts of coolant will remain in the engine block. You will want to totally flush and refill AFTER replacing the radiator to get all the crud out of the system. Unbolt radiator and disconnect any other items still attached (transmission cooler, temp sensor wires, etc.). Remove radiator and replace with new, reattaching all items removed from old radiator. Inspect other items and possibly replace suspects. Reattach hoses and make sure the clamps are tightened without pinching hoses excessively. Do a flush job with water/radiator flush, making sure the water runs clear out the draincock. Instructions for flushing the cooling system are usually printed on the radiator flush bottle. Be sure the heater is on and the engine warms up completely to open the thermostat. SHut off engine and drain as much water as will leave. Fill with 50% coolant mix (Dexcool or equivalent). Estimate water remaining in the engine and add 100% coolant to balance. COmplete fill with 50% mix. Remove air by running engine until warmed with the radiator cap off, adding coolant mix along the way.
