This is the the thermostat that I pulled out of it. The previous owner put the motor in, it is a brand new jasper 350. He said the stat was new. It was jammed up inside the thermostat housing and I had to pull it out with pliers.

I put a new 180* stat in last night along with a new high volume water pump. I put them on and bled air out of the intake. The stat opened because at almost the same time the electric fan turned on the radiator got hot.

There is no heater in the jeep and the heater hose port on the water pump is just plugged, there is no bypass hose running from that to the intake. Is that an issue?
