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

The issue of air collecting in the Pantera radiator can be resolved in one of two ways. (1) The simplest way is to install a manual bleed valve (drain petcock) in the top of one of the radiator tanks and develop the habit of regularly bleeding the air from the tank manually. (2) The better way is to revise the coolant recovery tank to perform as a head tank, thus providing a functional place to plumb the radiator vent within the cooling system (radiator venting can then take place automatically).
