Ok..

Scan gauge reads 200-1000MPG on my vehicle. But works fine on others.

Overheated today when offroading.

Loosing coolant.

Transmission temperature light will not go off.

E-fans probably never have worked since I owned the vehicle.. Replaced one.

 

E-fans will not cause overheating if your cooling system is running 100%...i had mine not working for over 2 years without overheating and i live in florida. i have overheated with the fans working so there you go... I think its a little ore deeper than your fans...most likely the LR curse...

good luck, chris

 

Usually the sending unit is bad on the tranny temp light. Probably caused by the overheat. Get a new one.

YOur evap fans should come on when you turn on your a/c. Not just an overheat situation...

Find your coolant leak!

 

couldnt of said it better myself!

 

• Check your Thermostat - mine was stuck closed
• Check your thermo fan clutch - the fan should make a lot of noise when the engine is hot. (like when you are stationary in traffic on a hot day!)

These were two issues I had which caused my cooling system to boil over, blowing the valve on the cap and spewing coolant everywhere.

The thermo clutch was hard to trouble shoot at the time but with the new clutch installed the fan really roars when it gets hot. - now I know it is working!

Bad advice, those fans serve 2 purposes, 1 for cooling the condenser the other for stop and go driving in town especially in the summer.
As for the exception mentioned, I haven't seem a D1 with a cooling system at 100% since they quit making them.
Replace the fans, ASAP.
Here again when it comes to the tranny, is the light always on or does it come one shortly after driving a couple miles?

 

I will add that I agree with Mike. My cooling system does not have any leaks, but probably isn't 100% because I have never changed the radiator. I will say that is traffic and only one fan with the a/c on, the temp would climb a little. Even one fan out will amke a huge difference. I replaced one bad fan (actually 2, the other was a little weak) and I can hang meat in the Disco when it is 100 out.

 

ok guys I have a question (in regards to this post) I just pulled out the one condensor fan that was not working, I don't have a replacement yet but will be getting one soon. my thought was this: because the fan is not working all it is doing is restricting air flow, so by removing it I figure I was helping the situation. Is my thinking correct or did I make a mistake? also has anyone ever been successful at removing these fans from the front (through the grill opening) or was I supposed to remove the condenser first? I had to do alot of work to remove it the way I did but I would like to believe the other way would have been more work!

I would also like to point out that with one fan out my A/C is ok (freon level is good) but only in the front seats (and that could be better), the front and back A/C on together kills them both, can't wait to see if it improves with a new fan!

 

The light is on all the time.. May be dirty.

As for removing the fans. Removing them from the front is the best way and if its not working removing it wont hurt one bit.

 

I removed mine from the front. Having the grill guard in the way made it a challenge. I left the grill off while I had the fan out and was looking for a replacement. It may have helped a little, but the a/c was still warm. I can tall you that I have an icebox now. Both fans replaced.
