Mein Auto: S54 M Coupe x2, M52 Z3
My water pump blew out on my M3 on Christmas Day of all times. The worst day to have a total breakdown.

Radiator, water pump, thermostat housing, hoses, etc. Full cooling system replacement basically.

Its not that hard to replace the water pump, just takes time. I would go with a stewart warner pump and an S54 radiator just for the peace of mind.

I bet you wouldn't have to worry about replacing it for a long time after that. Its not very complicated though, I would just jump into it and get it done one weekend.

Or you can just wait till the coolant runs up your hood and sprays your windshield, thats a good indication that the system needs service.
