Reply to "New motor, coolant temp creeps up between 195 & gets close to 230"

220 is about what you want that engine running at. This is a pressurized system and hot is 240 to 250.

195 is not what you want. That's too cool. You will get accelerated engine wear and will make less horsepower.

The Pantera CAN develop trapped air in the coolant system. Some cars seem to need to be stood on their nose to get the air out. A simple method would to just pressurized the system manually. You will hear the system belching out the air doing that.

The stock cooling system on the L's is quite capable of idling all day with the A/C on in the heat of the Phoenix summer.

You want the oil temps to be in the 215-220 temps also. Some of these cars are over cooled now.
