8 Sept 2018 - engine temp sensor installation

Today I installed the original style temperature sensor.

I drained about 4 quarts of coolant so that when I replaced the temp sensor at the intake manifold, I wouldnt have coolant everywhere.

The drained coolant looked pretty good for two years.

After installing the sensor, I filled up the radiator and overflow tank with Prestone 50/50 coolant.  That took about 30 minutes or so to burp the cooling system and get the proper level.  I will continue to monitor the coolant level.
