I tested and refilled coolant. I reused the same coolant but poured it thru a funnel lined with a paint filter to catch impurities.

On my first attempt to R/R the thermostat I bought a standard thermostat (shown) that clearly doesn't fit this housing.

Easy to release this plastic strap by depressing the tab. Attached to the aluminum thermo housing.

I did not have any issues with air pockets in the coolant lines, maybe because I didn't drain entirely, But by loosening this plug air can be released.

The old rubber gasket was torn and a contributing factor for the code.

Pic shows how I used my red bench vise to secure the thermo housing and used a heavier blue vice as a pivot point to use the wood to compress the thermostat while twisting the wings under the tabs.

Closeup of the 3ft piece of hardwood that I used to compress the thermostat. Needle nose plyers are good for maneuvering the wings in place.

I needed to reassemble the old unit, since I did not have the correct replacement. I cleaned the old core with sand paper, reseated the rubber gasket and reassembled by compressing and swinging wings under tabs.
