It got too hot too fast! I decided to change the spark plugs and t-stat in the Silverado yesteray. Wow! I thought it would be easy compared to the Camaro but the coolant just wanted to go all over the place and even with all the room, I need to stand on a step ladder to reach into the engine compartment so I was leaning over on my stomach for way too long. Sweat pouring down my face and glasses too. The spark plug wires didn't want to come off and then the plugs were baked in place pretty good. At least I got 2 hours in floating down the river in the boat. Just got back from a mountain bike ride today and I'm totally overheated.
Guess it's time to hit the boat again before the storms roll in.
