Yes, the D did over heat last time. I blew a hose on the water pump. But the needle never reached 240°F on the gauge. It came close, but it didn't hit. (it was 2AM, no cars around, so I pulled right into the Stratosphere parking lot). When I first got my D, I blew the otterstat, and that time the temp almost hit 260°F! But, at that time I had a Valvoline oil filter installed, and it looked fine. Every other filter on the D has always come off by hand w/o the use of a tool. And because of the harsh temps here in the desert, I ALWAYS run Castrol GTX 20w50. I do appriciate the advice, and the comments. And I do mean all! :) I figure to clean everything out, I'll probably run a little chemtool thru with some cheap oil to clean out the motor. Benefit of the doubt against myself, I'll always be careful to make sure that I don't over tighten the filters from now on. But like I said, I never had this problem before... --- In dmcnews@xxxx, "dmcman82" <dmcman73@xxxx> wrote: > Has your D ever overheated?
