How old is your rig?

[Mortblanc]

I did not test the thermostat in boiling water. Due to it being at least a decade old it needed replacement if there was the slightest chance it was posing a problem and the cost for thermostat/gasket/glue was less than $20 US and the repair took all of 30 minutes.

I made the trip with no incident. Everything seemed to remain at under 200f where it belonged and no fluids exited the vehicle that I could tell. I will need to drain the water that is now in the system and replace it with proper coolant/antifreeze.

However, on the way back from the dump I rolled the window down, then up, and something popped. The window slowly fell to open position and stayed there. I have worn out the power window, which depends on a plastic screw for control. That screw is now in pieces in the bottom of the door panel.

A replacement regulator is already on order. As I said earlier, when these rigs hit 20 years there is something going wrong all the time.
