Been thinking.. ouch!

Once had a cam belt go on a Rover K series that had a leaky water pump...

Now, lost the coolant tank cap on a long drive out the other sunday in Bumper and coolant was sprayed onto the cam belt. DOH!

Any risk peeps??

I think you'll be OK.
Cant see the link between the leaky pump and belt breaking,
unless it slipped, or the pump bearing was knackered and was twisting the belt??

I've not had a broken belt that I'd attribute to coolant contamination. Plenty of oil caused failures and stones, etc (note all those running without covers) getting in and doing it.
I'd say either the belt breaking was just coincidence or the pump bearings caused it.
