Yes, this is a stupid sounding question (at least to me) but how can I tell if my thermostat is stuck open? The temp gauge barely moves in the summer time and in the winter, forget it. I do get heat and it's hot but it takes a LONG time. I finally put a cover over the upper grill and the gauge moves two clicks and I get heat a little bit faster but again it's not all that great.
Also, when I say getting heat faster I'm talking about driving. I know better than to idle the car and attempt to get heat
I don't know if it's just because the engine is that much bigger but my 7.3 powerstroke seems to heat up (to the point where I get heat in the cab) much much quicker.
I don't know if this is just the nature of the VW TDI or if my t-stat was open. As far as fuel mileage goes, I've been consistently getting higher mileage in the 48-50 mpg range in the summer and 43-46 in the cold...just if that helps in the diagnosis.
Thanks for your input!
