I do agree with this approach ... Thermostat is definitely new and both hoses look like they have been replaced relatively recently.

Water pump is definitely the original, rust on shaft and oxidation on the aluminium housing. At least on the 4cyl M43TU engine it is easy to get to.

Next job, change the DISA valve which is getting noisy and get window regulators ready for the inevitable!

When I bought the 325i two years ago, I found the thermostat not working and changed it, both hoses and expansion tank. Water pump was removed, checked and replaced with new gasket.
