O COLLECTIVE WISDOM OF THE LIST... Last week, driving across the hot deserts of Utah and Colorado (Salt Lake City to Crested Butte, through ambient air temps in the 100-110 range), we used Vic's (our '90 Syncro Westfalia) AC. It worked great -on high the two of us in the front were plenty comfortable. However, the temperature needle on the dash kept climbing. At cruising speeds of 70-75, the needle was just to the "hot" side of the led, and with strain such as hills or acceleration, it would climb to about 2/3-3/4 the way to the top of the gauge. The fan would come on appropriately (However, there seems to be only 1 fan speed), and no lights on the dash would light up. Going down the hills, the needle would tend to drop somewhat down the gauge. There was no evidence of coolant loss at all. (By the way, RPMs were mostly below 3800) This brings up several questions: How high on the gauge is too hot? Is it possible that there is a cooling system problem? (the H20 pump was replaced about 500 miles ago!!) Is it dangerous to the engine to run it that hot? Any info appreciated, Thanks... John Silverman |
