I read that radiators and water pumps should be changed around 60-90k as preventative maintenance.
I was looking at getting a golf r32 at about 100k miles. I asked sellers if water pump and radiator had been done and most of them including traders(that give warranty) said these parts can go on for a while and you do not change them unless they break.
With cars in general, should you be changing these parts at 60-90k?
Is it the case that cars like golf r32 have higher quality water pumps and radiators compared to cheap cars such that you don't need to replace them at 60-90k?
