Dang FastDEW that is good info. I didn't know Diesels would do that. Considering the mass of the engine and torque the produce I always thought they were hot running engines. Who would have thunk it?

Jdmcbride Florida is like SoCal (but much more humid), I hardly ever use my heater here but sometimes we do get cold spells. Fact is, many times I'll turn the heat controls to hot just to flush out the heater core even though I don't need it. Just don't want the water to corrode the pipes just sitting in the same place for months on end.

 

I have not driven Fords for more than 30 years due to some issues I had with Ford's position on product quality. This past year I decided to look at their products again and purchased two of them. One is a 2009 Fusion, the other is a 2010 Mustang GT. Both are very good cars and much different from the ones that gave me trouble in the 70s. The heaters and AC on both cars are great. My wife has a 2007 Tahoe that is also a very good unit but, the heat and AC are not up to the standards of the Fords.
