Maybe, Driving home last night in my '97, temp never got above 195, mostly was at 193 so I am guessing it has a 190 thermostat in there. It did drop down to 183 once or twice..

 

What was the temp outside? Did you have the AC on?
Some have replaced all that you have and get cooler temps while others nothing over 200.

 

no a/c (just to keep everything the same) and temps at night were 66-70 degrees. tonight same temps with temps outside around 65

Still waiting for a new thermostat on the '99.

 

Still waiting for the thermostat... so much for Amazon's delivery schedule...

 

All these protest has most deliveries behind schedule.

 

Last time I checked, roads were built for vehicles. People need to stay off them unless they are driving a vehicle.

 

Enough of that!! got the new 180 thermostat installed, filled at the upper radiator hose, purged air at the plug in the radiator, heater on full, and temp is sitting right around 207 with a OBDII reader. Still have one wheel up on the curb, but maybe do a test drive tomorrow. Didn't want to get stuck on the road with the grandson in the truck.

 

AHAH!!!! tried turning on the motor, and A/C on max, front fans did not start up!! verified that my 97 does act the way I think it should, motor on, A\C on and fans were running!!

Doesn't surprise me as I have seen some strange wiring configurations on this truck. A\C does run so I doubt it is a fuseThere were brand new Warn aux lights mounted on the grille guard (which has not been put back on yet) so maybe.....

 

Check your viscous fan clutch Had the same issues you’re describing and the new fan clutch cured it, and this was with the A/C aux fans not working either.

 

I took a look and notice there is some play when I move it in and out, shaft stays solid, and when I spin it a bit, it spins quite freely after a few turns. I checked my other Disco and it stays pretty stiff when I spin it a few times. Guess it needs replacement. Thanks for the heads up!!


still no luck with the AC radiator fans. Have not gotten to the K109 relay yet. gotta stand on your head to get to it. I did find one of the other relays was corroded in th eupper corner... not sure how that happens as water usually collects at the bottom not the top.
