Re: how hot does your engine get>
That temp is right around 200-205 degrees.
The AC and engine coolant are two totally seperate systems. Your engine uses a radiator and coolant to maintain temps. Your ac using R-134a refrigerant, basically like a window unit. Your engine gets slightly hotter when you run the ac because of the heat that is being dispersed from the coil in the engine bay. The car feels sluggish from the ac running because your engine powers the compressor, which is the heart of the ac.
Refrigerant does not get "used up". It is a closed cycle system. If you ever have to add 134a to the ac, then there is a leak somwhere.
Jeep is gone, lots of good memories, lots of turned heads. Now driving a 2013 Charger RT blacktop!
