Default 91 prelude fan keeps running for a long time please help

hey folks,
i just picked up a 1991 2.0 si prelude with a 5 speed.

after a drive when you shut the motor off and get out of car the fan will come on.

ok thats not so wierd. i have also had an 89 prelude in the past and 90 accord. its normal i am pretty sure.


but with this car it will stay running for 20 minutes plus. today the car had been sitting for 2 days or so and i went out to start it and had pretty much a dead battery. so i jump it take it for a long drive battery is charged back up. cranks right over. get home park it. fan starts running again so i go inside eat and come back out 25 minutes later. fan is off and battery is almost dead again.

what could be the problem? is it a bad temp sensor or something?
the car is at normal temp too. not to hot or anything.

thanks for the help.
ryan

you can do a coolant flush - maybe the stuff isn't good anymore. there's also a thermo switch that controls the fans, but I don't have the manual for the 3rd gen on me. that might need replacing.

thanks for the replies. i am gonna check out that switch tomorrow.
i have the 79-89 manual from my previous car but it doesnt cover this year. although they are very similar.
