The rough start might be contributed to the fact that i have a leaking head gasket and coolant is leaking into the engine. (something i need to fix real soon) I've noticed that i have to refill my radiator every so often, yet there is never a leak under my car when i have it parked for any period of time.

Well...you didn't mention that.

I live in Vegas.....115 in the summer, I have a 180 T and temperature rarely goes over the middle of the gauge and goes below when driving or stays in the middle. I run A/C full time (240Z).

Percolating is my problem even I have an electric fuel pump I start on severe heat condition combined with the mechanical one. It idles better in traffic.

But, this spring, I made the decision to install a pusher fan in front of my A/C condenser. I will see if it will help my A/C to perform better in severe desert conditions.
