Whenever you shut your car off after driving for a while the radiator fan is suppose to come on for about 10 minutes or so. Maybe longer. Thats normal.Originally posted by 91 DXComment

It should not come on and off randomly though, that is not normal. And it only comes on at 230 degrees, which is very hot. It will run a few minutes and then shut off.
This happened to me and it was the sensor aka switch for the condenser fan. It is the green colored switch on the top radiator hose inlet near the head.
You can test it out by disconnecting the switch and bridging the terminals in the connector while your key is out and engine is off. The fan should come on and stay on as long as the terminals are bridged.
good luckComment

I believe the fan timer unit only operates the fans when the engine is on, and should only operate when the A/C is on. So that was a different problem.Originally posted by ceelooboob
There is also a switch near the lower hose inlet on the thermostat housing, which only operates the radiator fan while the engine is running. It somes on at lower temperatures.Comment

MY cb does it all the time, on cool days when i shut the car off, it doesnt come on
on hot days it comes on.
even on cool days when i beat the shit outta my cb, the fan will come on.
its liek a timer/temp sensor or something.

Don't know if it's normal but mine does the same thing bro. Only I notice it when I'm in stop and go traffic on a hot day...my noisy ass fan will kit in and sound like a friggen jet...then like 5 to 10 minutes later it goes away

my car does the same freaking thing, so i actually have to wait like 5-10 sometimes (depending on how long i drove for) to set my alarm because i have it set to sense current draw and the fan sets it off. for the longest time i thought it was my door triggers.
but where exactly is this timer or whatever you guys are speaking of and whats the name of it so i can at least attempt to fix this because its annoying to have to remember to set my alarm after ive already gone in for the night.
thanksComment

if its happening like everytime you drive, theres something defintly wrong. could be the fan timer unit like stated previously. or car is running a bit hot which turns the fan on after you turn off the car.Comment

This is wrong. The fan timer also kicks on the radiator fan alone when the engine is off after its been running for a while, it also shuts the fan off after a certain amount of time. Hence the term fan timer.
The ac switch controls the condensor fan(4 blades) only. When idling at a stop light or sign BOTH fans are suppose to come , depending on your thermostat type, when the temperature hits 185 or 195 or higher.
If you are idling and only the radiator fan(5 blades) comes on then there is something wrong with the ac switch/circuit or the fan motor itself. If both fans dont come on the thermo switch, relay, motor, fan timer, fuse, or circuit is badLast edited by Fake Thug; 09-09-2007, 03:01 PM.Comment

My car does the same thing but in your case I would check the relay and the timer that's under the driver side near all the fuses eventhough I doubt that would be it.Project EP hatch on the way

my problem was when my car was shut off key out of ignition just parked there....the fan would come on out of no where...it could be sitting for an hour and all of a sudden the fan would just turn on....chaanged fan timer and my prob was solved....had nothing to do with my ac or engine being on.Originally posted by 4CYLPOWER92Comment
