The other day I pulled into a parking lot and turned off my truck as usual. I noticed a funny noise, but thought it must have been the car next to me. When I got out and walked in front of my truck, I realized the noise was coming from mine. It sounded like the fan was still running. Not freewheeling, but actually running...like with power, but the engine was not on. I got closer and listned just to be sure.
I got back in and started it up, then shut it down again and it went off.
Anybody ever heard of this? I used to have a Chrysler that did this, but it was supposed to. The Rover has never done it before or since, so I am thinking it may have just been one of those Lucas-things.

Mine does it every time I've been running the a/c on a hot day then shut it off. It always turns itself off after a couple of minutes.

If the engine is hotter tan 230deg f or fuel is hotter than 158 the fans will for 10 min after the engine is switched off.

They are setup to do that but one thing you might check. Rovers are built for extreme conditions, hot and cold, and the rig does a good job cooling on its own to keep a consistent temp. I would check the radiator and maybe flush it and check for mud and debris between the radiator and A/C unit under the shroud and clean. This maybe an early sign to things to come.

Ok. It was about 95 out, and I had the AC cranked while in stop and go Myrtle Beach traffic, so it makes sense.
Thanks

My fans only come on when I've been running the A/C. I can be pulling a trailer that is loaded w/o the a/c and it stays at a constant temp. Fans only run after I shut it off when the A/C has been on.

Greg,

There is a thermostat in your electric fan that will turn it on regardless if the engine is on or off if it requires extra cooling.

Parked mine at the beach and noticed the fans on for the first time, thought huh no problem.....
When I got back ( +/- 1 hour) fans still running but now battery too flat to crank !!
So every time now I make sure to turn off A/c and make sure the fans are not on.

I think everybody should know that the English are not known for their electrical systems. I've had a couple of problems that made me crazy. Thank god I am an electrician.
