After-run Fan and aux water pump??

[geordiedubber 0]

Ok Ive done a search but cant find the answer to this, How long after

a run should the aux water pump and cooling fan stay running for ?

 

Does it depend on the engine temp ? I would have thought that to be the

case but even after a very short journey with the temp not going over

70 they still seem to run for a long time ?

 

The battery and alternator are only about 5 months old and twice lately

my batterys been flat, The batterys getting charge and holds charge

(when disconected) and am wondering if the pump and fan are staying

on all the time...

 

 

thanks for any help.

thanks for that dutch, I did see that but just was'nt sure if i had a problem

or not, Just been out on a short 5-10 min run, got back and they were running for 15min before i disconnected the battery to stop it draining it?

 

so witch sensor do I replace first ?

 

cheers.

Yellow sensor in the thermostat housing controls this.

 

- Check that one of the plug wires are not loose touching earth.

 

- Check when the engine is doing it the yellow sensor across pins 1 & 4. It should be open cicuit if the engine is cooler. If closed circuit, it's signalling the fan controller to run the fan with engine off. May be simpler just to pull the plug off the yellow sensor. If it's causing it, the fan should stop.

 

- It still runs with the yellow sensor disconnected, then suspect the fan controller. But just check the wiring is OK going into the controller underneath it at the plugs.
