These aluminum water pump screws are single use and must be replaced each time they are removed. These are used on all 325i, 328i, and 330i with the BMW N51 N52 and N53 engines. They were also used on some early N54 engines that have rubber mounts on the water pump housing. Do not use these bolts if your N54 water pump has been replaced with a housing that does not have the rubber mounts.

In German, Rein means Pure. In the automotive industry the Rein name has quickly come to represent quality. With fitments for some of the world’s finest automobiles including BMW and Mini and guaranteed OE quality, Rein is a name you can trust.

BMW has an ongoing issue with oil separators freezing in cold weather if driving is done before the vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. The crankcase breather valve is used to purge the oil vapor from the engine block into the valve cover. However, sometimes condensation can cause it to freeze, causing the entire oil separator system to fail, crack, and disintegrate. Replace this and all the other components of the oil separator system to prevent damage to all the aspects of your engine. As long as you have everything off, you can rest assured that new parts will last and be reliable.

Rein OE Quality Automatic Transmission Service kits address the short-lived valve body sealing sleeves and adapter in the ZF 6HP transmissions. This kit includes the necessary direct-fitting sealing hardware to conveniently service the shrunken valve body sealing sleeves during the recommended fluid and filter change interval of 62,000 miles / 8 years at the latest. The ZF 6HP19Z series transmission is a very durable and powerful unit that can last for many miles if serviced in time to allow the valve body to maintain proper fluid pressure. The slightest drop in valve body fluid pressure in this unit leads to premature transmission bushing and or clutch wear, along with contamination and overheating of the fluid. Rein recommends the OE or Pentosin ATF-1 synthetic automatic transmission fluid for this job.
