Need a new radiator...which one to get?

[pepe88]

Found out my radiator is cracked. What brand should I go with? Might as well pick up a water pump while I'm at it. Which brand of water pump would you recommend?

Depending on your time frame, i'd either go w/ Auto Parts at AutohausAZ - OEM Auto Parts - Discount Replacement Parts, Resources and Car Care Tips or just head to the stealership if you need the X right away. BMW knows this is an issue, so they've fortunately reduced the pricing of the radiators. As for coolant, you can save by using Zerex G-05 from autoparts stores, otherwise get the BMW stuff. It has to be phosphate free, but don't buy into those Prestone, etc bottles that say they work on all makes, all models because they don't.

Performance radiator had the best price on the radiator on my X5, and had it in stock. (actually was cheaper than at cost at the dealer)

I used that radiator (fit perfectly) with BMW coolant and distilled water. No problems here.
