BMW DIY Video – Replacing Water Pump and Thermostat on 6-Cylinder M50, M52, M54, M56, S50, S52

Feb 2 15


The Bavarian Autosport Ultimate Maintenance Schedule (blog.bavauto.com/go/maintenance) is invaluable for BMW and MINI owners who wish to do all they can to keep their Ultimate Driving machines in top shape.  At BavAuto, we have been working on completing sample DIY videos for each of the maintenance tasks listed on the Ultimate Maintenance Schedule.  In this DIY video we will cover the water pump and thermostat replacement on the BMW 24-valve 6-cylinder engines from the early ’90s through the mid 2000s.  These engines are known as the M50, M52, M52TU, M54, M56, S50 and S52.

BMW and MINI water pumps don’t last forever!  Big surprise, but it is true, and not just for BMW and MINI.  Water pumps will eventually fail and when they do it can be an inconvenience, at best, and a major catastrophe at worst.  One of the problems with BMW and MINI water pumps is that they do not always give an early warning of impending failure.  In these cases, you will be in need of a tow (possibly at the most inconvenient time or place) and, potentially, in need of major engine repair.  This is why BavAuto recommends periodic replacement of the water pump …. before it fails.

This video will show the specific water pump and thermostat replacement for the M54 engine in an E46 3-series (99-05).  The general steps will be the same or similar for all 3, 5, X and Z models that use the M50 through S52 engines, as noted above.

BMW DIY Video – Replacing an Under Car Fuel Filter – How To

Feb 2 15

The Bavarian Autosport Ultimate Maintenance Schedule (blog.bavauto.com/go/maintenance) is invaluable for BMW and MINI owners who wish to do all they can to keep their Ultimate Driving machines in top shape.  At Bavarian Autosport, we have been working on completing sample DIY videos for each of the maintenance tasks listed on the Ultimate Maintenance Schedule.  In this DIY video we will cover a common under-car fuel filter replacement for applications that have the filter mounted under the chassis.

This DIY video will show the specific fuel filter replacement on a 2005 325i (E46 chassis).  The steps shown here can be generally followed for all under-car fuel filter applications, whether the filter is located above the rear axles, under the driver’s floor area or any of the other under-car locations.

BMW DIY Video – Installing Koni Sport Shocks in E36 M3 – Cut a Strut

Jan 23 15

Here’s a DIY video, done by Koni’s Lee Grimes, showing the procedures for installing Koni Sport shocks on applications that require cutting and re-using the original front strut housings.  In these applications, Koni has not manufactured a complete replacement strut assembly, typically due to unavailability of the lower spring seat or some other part of the original housing.  In these cases, the original shock cartridge is removed by cutting the strut housing. The Koni insert is then installed into the empty strut housing.  This procedure may sound intimidating, but it’s really pretty simple, as the video will show.

The only BMW application that uses this “cut-a-strut” design is the E36 M3 (95-99).  The sport shocks do come with instructions detailing the steps for modification and installation.  This DIY video uses a Subaru strut/shock as the example, but the steps are identical to the E36 M3 application.
