Got a 351W and I just fired it up for the first time. Using a 180 deg Thermostat it ran hot, ran about 215. Went to a 160 deg thermo and now it runs at about 185-190. This is idling and with the fan on; as car is not yet finished.

Spoke to an engine builder I know and his take is the problem is air in the system. I tried burping it using a barbed fitting at the thermo housing in place of the heater hose plug. I attached a piece of 3/8 " hose to it that went above the filler neck. That seemed to get a lot of air out but it still seems to be running hot.

Any recommendations as far as burping, burping methods,or anything else I should look for to try to get the temp down.
