Noticed a bit of a rattle a couple of days ago. Popped the bonnet today and it seems the water pump is on its way out. It’s my only car and I use it to commute to work, round trip 20 miles per day. I’m planning to take it to my local mechanic on Friday morning, should I be concerned about driving it for the next four days? Also, any idea of cost? Europarts has a pump for £130 so maybe a couple of hours labour, £250 ish? Thanks in advance!
