noticed that DG has a kit which prompted the question. Drove up a mountain road a few weeks ago and was surprised how fast my temp gauge rose but also not sure if gauge is reading correctly as needle rises and falls back to 80 inconsistently. Coolant is clean, t-stat seems to be operating correctly as is fan clutch - ordering a new temp sender and also running a new instrument panel ground tomorrow to see if gauge stabilizes as a result of improving ground -
