Hi guys
Welps my 65 GMC 1000 V6 was running so fine and then ...
(stop me if you've heard this) it started using oil which it had not done much before.
Then I noticed the original bronze radiator had started leaking. Tried to fix it but also ordered a cheap chinese alluminium radiator, until I can braze better.
I ended up putting in the aluminium with a better metal drain plug with zinc anode. Thought all was good but then it lost water from possibly a leaky bottom hose clamp and over heated badly. Barely made it home.
Put a new clamp on and fresh antifreeze and checked for leaks seems to be good.
And now I have to figure out whats going on.
maybe thermostat or waterpump? But the oil use worries me too.
First question: Should I use 30W or regular 10-30 for my 302V6?
AND should it be detergent or non-detergent?
Thanks Roger
