For some reason, the thermostat that is installed, slowly warms the engine up. The thermostat is a 180 degree unit. I decided to replace it today and install a Motorcraft 180 degree part. If that is still too cool, I aslo have a 192 degree Motorcraft thermostat that I can install.
At this point, the thermostat and housing, hoses/clamps are installed. I am letting the RTV cure overnight and tomorrow I will fill the cooling system and road test.

| Thought I would test the unit before installation. It worked like it should, so it was installed. |

| This is the RTV I used for this installation |

| This is the thermostat that ran very cool, it is a 180 unit but ran more like a 160 degree unit |
