Thanks everyone for their ideas. It seems unanimous to swap out thermostat for premium (or OEM) and change coolant. I kinda thought that but wanted to make sure by asking the resident experts.
BurbMan my plans are to to fix this up and sell it to friend or coworker. Every now and then something comes my way needing some work and I try to bring new life into it and pass it on.
BenK I didn't think of the removed thermostat because in the past when I had some that were stuck open (Mustang and Accord) the temp gauge wouldn't move at all and the heat was almost non existent but will update when the work is done. The previous owner "donated" vehicle to charity. Looking at some paperwork it still had factory warranty up to 2012. The worst part of these are the air suspension and it is in operating condition so it is just slightly neglected LOL
