After I turn off the car and take the keys out, the fan keeps running under my hood. I don't know if this is supose to happen, but yesterday it drained my battery, leaving me stuck at school. Now, I'm wondering if the fan is even supose to run after the keys are out of the hole.

I talked to my friend's dad , who is a mechanic, and he said it might be that the ignition screw is too loose. If that's so, how do i fix it and how much would it cost?

thanks.

 

its suppose to do that

 

The fan will turn off eventually, its not something thats broken its what its supposed to do.

 

The engine and coolant are still hot so the fans keep running on a timer after you take the keys out. Of course if the fan was running long enough to kill your battery either . . .

a) the fans ran TOO long, longer than normal and the timer may be bad
b) your battery is crap and you should get a new one anyway OR
c) your alternator is dead in which case you can charge the battery all you want and your car will still be dead every 10 minutes

 

When the coolant heats up, there are two switches that come on, to control the fans. One allows the fan to turn on when the coolant gets to about 198, the other switch closes when the coolant reaches 215 or so... the first switch turns the fan on and off while the engine is running, the second switch is only used to allow the fan to run after the key is turned off. It is not common fot the engine to get hot enough that the fan would run after the key is turned off. I have to suspect that the fan is not turning on when the engine is running (common problem). Check into this and see if, with the engine running, the fans will come on. If not, you need to repair that issue first.

 

u should check the temp sensor. A false one could tell the fan to turn on forever.

 

Sounds like your dads friend is the loose screw, his honda knowledge is zilch, zero, zip, nada.
Don't worry...this always happens on the 1934 Accords. Usually the cummins 12 cyl diesel makes the flangthorpe over heat. If you have the optional 18 speed trans, try to stay in the lower gears. Use high temp grease on the muffler bearings!!!
WHAT COLOR IS THE CAR ??????

LOL LOL ... make sure ur dad's friend does not work on your car

 

Fan Relay is bad. Had the same thing happen to me.

 

I've had this situation happen a couple times and found it to be that everything within the coolant system was in check and was indeed doing it's job. But I felt the fan was on too long after turning the engine off after decent run. What both issues turned out to be is that the radiator core had deteriorated so much it was doing it's job properly. I put mostly highway miles, so the rush of air in the front helped keep the engine within normal temp. range, that's why it didn't overheat on me...but better to prevent then be sorry. Check your radiator core, look behind the fans...it's a quick check, then I'd go check electrical issues regarding your cooling system.

: my fan is running when the car is off but not when it is running. What should I check to determine what's wrong? The fan relay is all good. Please help!

 

part 17

and you may as well change out the thermostat as well which is part 14

you must buy these from the dealer as aftermarket rarely last very long
