I'll try to keep this short. I've got a 1971 F250 camper special with the 390. I recently changed all the hoses for my cooling system, then my radiator started to leak. I got a brand new champion radiator and then my water pump gave up. I put in a new water pump and when I would stop I would get just two little drops from what seemed like the back of the pump. I couldn't figure out where it was coming from, so out of frustration I used Bar's Leaks 1150 (the two part system with the blue on one side and the aluminum on the other). I actually called Bar's and this is what they recommended. Now I am consistently getting drips out of the overflow. Any idea why? the truck has always run cool and never has overheated since I bought it. Any suggestion as to what is going on would be greatly appreciated.
