Sounds as if the water-pump on son's 1.25 Fiesta Zetec engine is FUBAR - not suprising as its done a fair few miles
As well as replacing the pump, aux. belt and thermostat whilst it's stripped is it worth slapping on a new tensioner pulley?
Thanks, Pewe10

VV Ta, Loggy and Jenko, will have a look.
Locost triumphs again - searched the interweb for ages and there you are a couple of mins after posting.

Without a doubt. Its usually the tensioners that cause belt failures.

I found a gates's kit on ebay for my puma engine (currently being installed in a J15), it included the water pump and cam belt kit and was a VERY reasonable price...maybe worth a look.

Just a quick update post new water-pump. The old plastic impeller had broken up and lunched itself on the shaft. Fortunately no major damage.
Loggy ^^ dead right new idler pulley a must - the old one sounded dog rough when spun.
Not too tricky a job but like lots of moderns (well relatively modern) access the main problem and requires a fair few parts stripped to gain access.
Replaced the thermostat whilst we were at it.

PS would rather have been Autosoloing!

make sure you got that crank pully tight, have a habit of winding back and killing the engine!
