I purchased a replacement radiator and the drain cock is defective, what size drain cock do I need and do you carry drain cocks that fit the replacement radiators?

Willys Jeep Parts Tech:
Depends on the radiator. Give us a call and we can try to help you.

I removed the drain cock from the side of the engine block and nothing comes out event if the block is full of fluid. Does this mean that the water jacket is so full of junk that it can no longer get to the bottom of the block? If so, any idea how to clean. Thanks.

Willys Jeep Parts Tech:
Sounds like it is blocked. I would definitely have it flushed out professionally.
