Great suggestions! This forum is awesome, I'm glad I found it!

Can anybody point me to leakdown test and cooling system pressure test DIY? I've never had to do either of those before.

Question about draining the coolant from the block: How in the heck do you reach the drain plug? Part of the subframe and the driveshaft block access to it. I can see it, but am not able to reach it. Is there a trick?
