Mike,
That's an awesome/terrible story but sure sounds similar to mine. I really appreciate the post.
- To give you an idea on space, there is 2" between A/C condenser and radiator, also 2" between radiator and water pump pulley mount bolts
- I put on new motor mounts about six months ago, a few months after I put on the new water pump.
- I haven't pulled the rad cap and done a pressure check, great idea
- I haven't pulled plugs in a while either, another good idea
- It's not filling up the overflow tank. Just the opposite, it's using coolant but not a serious amount yet
Tomorrow I think I'm ready to start with the water pump change. I'm putting on FlowKoolers 1671

It might take some time to report back to y'all cause I'm going to also remove headers and clean/paint the engine bottom since I'll have everything removed. It's the matching ser# engine with the truck ('70 C10), I'd like to keep it!
Once again, can't say thanks enough for all the ideas.
