Just had my MOT and they've noted some coolant crusting on water pump- told me to keep an eye on it for now and see how it goes. I tried looking after and couldn't see any crusting (guess they must have cleaned it up?)

Is it worth biting the bullet and getting the pump replaced now and avoid any risks of it failing or do you reckon I should just see how it goes?

*Quoted at £300 odd for pump and fitting :O guess I better get saving*

I'd follow their advice, check the coolant levels regularly and carry probably 5L of water in the boot for topping up.

Begs the question.. when was your timing belt last replaced?

Water pump's lifespan is usually double than that of timing belt.
If the pump is giving up it is likely the timing belt can go off at any moment and you'll end up with blown engine. Costs of repairing an engine after such failure can be much bigger than replacing entire motor for another one.

Not at all as far as I know- it’s a 15 plate AYGO with only 20,000 miles .

It’s a 4 year old car with 20,000 miles- am I being super naive to think that a timing belt should be working for much longer than this?

Could be the water pump gasket causing it to leak, especially if it was done up too tight causing the gasket to not form a proper seal. Had this happen to me a few months ago, white crusty stuff forming around and under the water pump. Managed to fix the problem with a £4 replacement rubber gasket and an afternoons work. My car was a lot older and has many more miles.

Ah, it's chain driven, not belt.

Hmm, should last more than twice more.
However I'm surprised there is any leaking issue at that age or mileage.

Then I advice just to monitor the coolant level. If it doesn't lower in a month or two, then just ignore that incompetent MOT guy.
