Ron61,
Thankyou for the suggestion. When I replace the water pump I'm upgrading to a better design for sure.
I was going to go with shaving the wrenches as a last option. I was pretty much thinking if the additive didn't work. I would just replace the gaskets/pump and get the radiator to a shop.
I lifted the cobra last night and that stuff really works. The water pump back plate and gasket was dry. The radiator leak by the vinyl nail dry also....absolutely no leaks!!!... I drove it into work today, a balmy 55 degrees. Still no leaks.
Jhv48, that's exactly what I wanted to hear. Thanks man.
I admit I wasn't a believer, but now I am. It's nice having piece of mind.
Maybe Bar's and Trojan should work together on a new product.
The additive I used:
"Bar's/18 oz. liquid copper block seal, intake and radiator stop leak"
$8.99 at Autozone.
Plus the label suggests to leave the additive in the system to ensure ongoing protection.
Thanks again guys.
