Let me start by saying, I understand the risks. I'd like to see if anybody has pics or knows if the oil screen pickup is viewable through the oil sensor or the drain plug (maybe with a boroscope), before I start down that path. I've pieced together the belt, and found it is fairly in tact. I'm...

I have a 2008 535xi with 192 000 km on it. Last month while on the highway my serpentine belt shredded. I had changed it two years ago when I replaced a leaking oil filter housing gasket,but I didn't replace my pulleys. Had the car trailered home, and started cleaning up. Valve cover and oil pan...

My 2011 335i coupe with FMIC and Cobb Aggressive tune just recently lost its serpentine belt, and I would love to understand why this happened. So any theories on the following would be welcomed. Of course, when the belt came off, it went into the engine through the crank shaft seal. In...

Good day to you all, I am the proud (but a bit sad) owner of a 2007 BMW 525i with a N52 engine. I bought it used (my first car) with a couple of minor issues but so far it has carried me 40,000+ miles. Back in February, I repaired a small leak coming from the coolant thermostat. A month later...

Hey guys wassup just made an account! So I need help my serpentine belt snapped on me yesterday while I was at a light. Lost Power steering, battery light came on, luckily I was a few blocks from my friends home! So I got it towed to a local shop here in des Moines, Wa, where they have done...

I just got my car back from the shop, had the radiator, thermostat, fan clutch, and serpentine belt replaced. It drives and sounds perfectly fine, however it is telling me to check the coolant level, which should be full, and it's telling me to check something else but the display is pixelated...

Hi I'm very new and don't know how to navigate through this site I have a 2009 BMW X3 driving on the highway and my battery and oil light came on red the car was still drivable trying to get to a place to park. While driving it felt like the poster steering went out had to he-man the turns...

Hi All, OK First off, this is my first post on here, Secondly it's about my mom's car, I drive an Audi (please don't hate me!) but respect all german cars. I am not the most familiar with working on BMW's so I figured I would turn to all of you for help. So the story goes; I got a call from...

I'm ready to make the serpentine belt and tensioner change - my car has 106,500 miles and it's time. I was able to easily get the upper air scoop/shroud out of the way but there is a second one down lower running from the driver's side, across in front of the belt/pulleys and to the passenger...

Hi everyone, I'm looking for some serious advise, help and direction here. Back in May I had the serpentine belt, tensioner and idler pulleys replaced on my 2008 e92 335i. When the upper idler pulley was being replaced it was over tighten and stripped the threads of the aluminum block. The hole...

I spent a very frustrating 2 hours yesterday trying to fit a new serpentine belt following the well known oil filter housing gasket replacement. The job had gone well until this point; and i was replacing the belt because although it had only 28K on it; it was looking cracked and questionable...

Hi fellow BMW-ers. I have an issue. I recently replaced my Serpentine Belt on my BMW. I am trying to tighten back to where it was previously with the old belt, but I cannot get the tensioner to go back to the previous state. If you look at this pic I found on the site...

740iL Serpentine Belt Tensioner DIY (& the difference between mechanical & hydro) I was doing some research for the E39 bestlinks when I came across a cn90 reference to a 2000 740iL simple hydraulic tensioner DIY that can be added to the existing tensioner bestlinks: - How to tell if you have...

Does anyone have a serpentine belt diagram for a 2003 525I? I replaced the alternator and the belt fell off. I have tried routing it and there is always around 12" slack, so I am obviously not getting it right.

Was driving home today. My check Engine light comes on and off. Mainly caused by the Vapor sensor (so i hope). So when it came on today didnt think anything of it. Then my battery light came on, lost all power stearing and car overheated. Parked it quick and got it towed to the house. Under the...

This was the first DYI job I did on my own. It should have taken about an hour, but it took 3 over two days. Most of the effort was in finding the routing of the belt (mine shredded) and in finding out how to work the tensioning to get the belts off and on. First, I will say you have to be...
