Nagging question on Clamps

[Frodo]

I mentioned this issue in another thread I recently started, but I eventually decided to go ahead and post a separate thread on it. It’s possibly an issue only for me (though I actually doubt that), but I’ll swallow my pride and go ahead and put it out there.

When doing work on the cooling system (and I guess other systems as well—the oil cooler coolant hose is an example that comes into play in my current DIY), the service manuals and the DIY videos and the various forum discussions all tend to advise: “Don’t reuse the spring-type clamps” (101 Projects for Your Porsche Boxster) or “Use new hose clamps on coolant lines” (Bentley service manual). Problem is, there’s no description of the clamps that’ll be needed, no part number, clamp diameter, etc. And when you go to order items like a new coolant tank, and water pump, and thermostat (all of which I just ordered), none of the suppliers bother to mention, “Uh, btw, you’re gonna need…[such-and-so specific hose clamps].” Nor do the manuals, videos, etc.

Why is that? Why do we need to get into the middle of a project before figuring out size and description of the clamps that’ll need replacing? Or…and I guess this is the key question: Despite what “they” always say about NOT using generic, hardware store-sourced worm gear type clamps, is it actually okay to do that? Or, maybe more to the point, is that actually what most people do?

In the middle of getting ready to replace my coolant tank, and, despite reading multiple DIY descriptions (which are all helpful, thank you so much!),` I really have no idea what replacement clamps I’m going to need. And, as I mentioned, the suppliers of what I’m replacing don’t even bother to mention clamps needed. Even the DIY vids that I’ve seen seem to just gloss right over that little detail.

I’d love it if there was a handy “Specialty High Quality Clamp store” right down the road, but I’m pretty sure there is not. So again, what do people do when they suddenly realize they need clamp(s)? Leave the car on the lift/jack stands several days while they order them and wait for delivery? Or…head to Home Depot.

I realize there are forum members here that have been working on cars all their lives, and who were probably born knowing the answer to questions like this. Not me. Never did any automotive DIY type stuff til I was in my fifties, when I bought the Boxster in 2006. So I’m definitely still learning. I’d bet there are others out there who would be interesting in learning about this subject as well..
