So after all these cosmetic updates, I went out to an AX event nearby to watch everyone run, and meet some of the local PCA crowd. The day was 95 degrees, and I ended up driving around for about 3 hours enjoying the car. When I got home I thought I smelled coolant, and sure enough, the next morning found a leak.
So, I drained the coolant, and removed the water pump and thermostat. The pump had broken impeller blades. I did a complete flush with distilled water, where the blades ended up coming out as sediment and debris. I then installed the new pump and low temperature thermostat from Pelican. And then refilled with the Porsche pink unicorn tear coolant. All in all, everything came out great.
