Hose Kit for 318ti? Cooling system maintenance.

[ergnut]

I'm planning to do flush my cooling system & replace the hoses (130k, original hoses).
Does somebody sell a hose kit, or is there a list of part numbers for hoses that represent the set of hoses I should replace?
What else should I replace - thermostat?
How do I check that the waterpump is still working well?
Thanks.

I know alleurasianautoparts.com has OME parts. They are good parts from Germany and a hell lot cheaper than those from dealers. Fast shipping and good service.
