156 sports wagon overheating
Hoping someone can give me some guidance. Been driving 156 sports wagon around and all of a sudden the water temp light and alarm came on. I pulled over and waited for 20 minutes then got going again and it was all fine. Towards the end of the journey, the temp was high but not at red light so I nursed the car home with fan on flat out. It was a cold day so fingers crossed haven't done any head damage. I checked water etc and levels are fine.
This coincided with the heater not blowing out warm air which from what I have read points at a water pump failure. Looking through service book, this was replaced complete with other parts approx 5 years ago. Would it really go again this quickly? Or could it be something simple like the belt being loose?
Thanks in advance for any help
