Have a 98 Dokata with the 2.5 and we're having a problem. The radiator fan will not cut off - after shutting off the vehicle you have to unplug the connector to get the fan to stop. Plugging in back in later (doesn't matter how much later) the fan kicks on prior to the starting the engine.

The temperature guage reads low except when my son forgets to plug the fan in and then it reads high.

My first thought is a temperature sensor problem but I'm not sure as it never seems to "reset" - could the sensor be shorted out and that be what's causing it to run continously?

Any help would be appreciated.

I had this problem hapen on my 4.7. I dissconected the battery so it wouldn't get flattened and left it overnight. When I re-connected it in the morning it was fine. Could be a tempory fault that got cleared by having the battery disconected. Try it instead of just taking out the fuse. If not, I'd say its the switch as they're normaly designed to fail in the on possition rather than off.

Hope this helps,

Paul

 

Thanks, I'll probably replace the sending unit first and then if that doesn't fix it - then the control relay.
My son is bringing the truck up to my place this weekend - evidently this has been going on for over 3 weeks.
Maybe some day he'll start jumping into these projects by himself
