Coolant Hose Clamps

[pandp38]

Hi all
I am wanting to change coolant and a few hoses on my 1.9DG. I notice a few of the hose clamps are the "jubilee" type and look quite rusty.I've read previously that worm screw clips shouldn't be used because of contraction/expansion of the pipe but yet Brickwerks, Heritage and others sell them. So are the better quality "jubilee" clips OK to use or should I look at getting the original type? If so where from?

Any ideas please?

Well, if my pipes were expanding that much, I'd have bigger worries. Just use good quality clamps. Stainless probably a better bet. Lots of places sell them.

There's basically two types of clamp - constant diameter and constant tension.

Jubilees are constant diameter - they don't expand and contract to compensate for whatever they're clamping. Overtighten, they cut in. Undertighten, they're slack. On the upside, they're cheap and everybody understands them, and they cope with a wide variety of diameters easily.

Then there's the various spring-clips. They're dead-easy to install in a factory, and are always the same tension. If they're the wrong tension, or ever-so-slightly the wrong diameter, though, you're stuffed. And unless you've got the right tool (and good enough access to use it), they're an utter PITA to fit and remove.

VW clips all day for me.

We sell Norma, that's what VW used.
Not found a reliable source of the spring clamps yet, when we do, we'll add them.
