My temp gauge on my 83.5 NEVER goes any farther than a little right of the LED even on the hottest days. And when it does it moves there slowly. First, you must bleed the system as per Bently but make sure the front is even higher than the 15 inches recommended. Also, make sure you have the Rpm's up to the recommended level too. AFTER this you let the van cool down overnight. There will be some air in the coolant tank (not the overflow), replace this with more fluid. Drive the van around the next day and get it good and hot. Let it cool overnight again. There will be more air in there. Replace it again. Keep doing this, mine took a week, every day until no more air is in that tank. BTW, this will make sure your heater works properly in the Winter too. In addition, I have one of those fan switches that goes on a few degrees earlier that I got from Kyle. Actually I rarely hear the fan kick on except after I shut the engine off. Bryan |
