from what i hear, and have observed on my buddy's 72 duster, the reproduction clamps, coupled with the thinner wall section hoses, don't clamp tight enough. i "think" the solution is to peruse the grainger catalog for the correct size "range" of these clamps for your application. thoughts on this ?
I agree. I've had several hoses pop off due to those clamps. Mainly lower radiator. I temporarily place a regular clamp on the lower rad hose until the next time I change the coolant. On the heater hoses going into the firewall they've weeped a bit. I moved the clamp around and it's stopped. Other than those hoses the clamps seem to be holding.
As a side note, make sure you use the proper clamp pliers. With using regular pliers the clamps sometime wont hold and will go flying. They can take out a windshield or chip paint.
