Took the Cruiser to our Boy Scout meeting with my son on Monday. When I parked I immediately smelled coolant.
Got out and I had a nice stream flowing onto the ground. 44 miles after rebuild at this point, i'm pretty bummed. Couldn't tell where it was coming from but it had blown (by the fan I assume) all over the engine. From what I could tell, it looked like it was dripping off the timing cover which made me automatically think water pump. I got it back home without overheating - just six miles. I parked it back in the garage and put a pan under it.
Fast forward to today, the truck had cooled off and so had I. Still wet around the pump and I could hear an occasional drip in the pan. I re-torqued all my water pump bolts to the specified 27 ft/lbs. That is fun to do with all the belts and crap in the way! Also re-tightened my hose clamps.
Thats when I saw a drip fall. It was coming from the BVSV 2 valve that I capped off where it mates into the thermostat housing. It looked like some corrosion on the threads. Maybe I upset it when I cleaned everything up and caused a leak. Maybe when it builds up pressure, it sprays out??
Lucky me, I had a Jim C. plug he sent me laying around that I guess I should have installed.
The BVSV was a pain to get out, but with a little heating from the torch, it let loose and came right out. I cleaned the threads in the housing real good and installed the plug with some RTV. Hopefully this solves the problem! Fingers crossed. I'm going to let it set up over night. I gotta get some more antifreeze tomorrow anyway. We'll test it then!
