Hi all, first post

Recently bought a 200 Tdi 110, loving it already.

I'm going to change the cambelt as a matter of course, just to give myself a bit of peace of mind.

I'm happy enough with the steps to change the belt, my question is, if (as seems to be fairly common) if you end up with corroded bolts (round the water pump etc) breaking off, what can you do about it? What's generally the way forward from there?

Seen as the water pump partially covers the timing cover, I'd say it's removal is fairly necessary!

In the event of a bolt snapping, the proper method is to removing the timing chest and remove the broken stud. My water pump is currently missing a bolt or two that have snapped over the years, some RTV sealant when re-fitting the waterpump along with the gasket was enough to stop it leaking. It's on the list of jobs for this year to strip the front of the engine down and sort them out.

That was my understanding of it too!

Thanks for that, can you just clarify how you'd go about removing the broken stud?

Get a set of left-cut (anti-clockwise) drill bits. They normally come as part of a set for drilling out broken bolts.

Yep, that or a stud extractor if there's enough sticking out to get a grip on!

is a while since i did one and your right must have been thinking of another ,but hitting bolt heads prior can help loosen stubborn bolts
