How's it going. I am new to the Forum and a new owner of a 1995 FJ80 Land Cruiser with 149,000. Over all my LC is in excellent condition. Mechanically it's been strong and not problems until recently. I've noticed on two trips I've taken up the Angeles Crest Hwy to the mountains that my temp guage starts moving dangerously close to the red and only when going up the steep inclines. When going downhill the needle starts to move back to the middle and is fine. I open the hood and see no problems. On one day only driving 60 fwy towards Pomona, again my temp gauge started getting very close to the red. I pulled over allowed it to sit for a bit, started on the fwy again and nothing. The temp gauge remained in the middle. I've taken it to the dealer twice and they could not duplicate the problem, or find any problems with the sensor's. Any suggestion on what else I can check?? Thanks.
