Mystery Coolant Leak

[Jerry Bransford]

Okay I'll bite how do you know? I have a leak from the top of the lower radiator hose. Replace hose twice and and worm drive type clamps 4 times now. Sometimes leaks, sometimes doesn't.

Worm gear hose clamps are crap, they are more prone to allowing leaks due to their inability to adjust their tension as the temperatures change. The constant tension hose clamps the factory installs keep the same tension around the hoses whether conditions are cold or hot.
