Radiator cap? coolant leak

Darwins Child

Our vehicle was purchased by its original owner in July of 2014, which means that the clamp has been in "hot" service for probably not much more than 2 years. How the heck it could have worn out in 2 years is beyond me. If it was indeed not holding the hose tightly enough, I bet it's because its spring steel was not quenched correctly by its manufacturer, or it was removed at some point and, as a result of that process, the clamp lost some of its tension.

This is why I think that it's best to stick with a clamp whose "squeeze" can be adjusted at will and re-adjusted over time.

This evening my wife and I went on a joy ride (I say "joy" because it included a stop at DQ to get my wife a banana split) that lasted about 45 minutes. No high performance anything, but when we got home I checked the usual suspect and there was no leakage whatsoever, so I believe I may have fixed with a clamp what an expert technician said required a new cap.
