Header tanks: keep a spare in stock!

[nicq]

With a faulty cap, normally the end result is under rather than over pressure. The greatest damage is usually caused by lack of pressure due to a small leak via hoses, pipes, worn pump, heads or rad and the water (and engine) gets hotter earlier. Thats not good for anything. Certainly if you have to top up fairly frequently there are problems that need sorting pronto.

Having resolved mine, I'm half expecting something else to give. Thats usually the way.

I can see your point but if there is no pressure how do the tanks split.

Age and heat/cold. Like the rest of us. That and inferior materials or manufacturing possibly.

I am also the victim of a newish header tank failure!

Ralph, where did you get a genuine cap for £7? A couple on the shelf wouldn't go amiss. Thanks.

Ebay fella, and there was only one left when I got it. I trawl a hell of a lot which is why I get such good deals.
