    6:31 take a 16" socket and turn the pulley tensioner body clockwise to push the pulley down. You will see two holes that will align once you push if far enough. Once you get there use a pin to fix it in position so you can add the belt later with ease. Once done just watch out that the belt is everywhere correctly and then slowly push the whole body so you can remove the pin and slowly drop it back while constantly checking all spots where the belt could lift off. This is not my tip but how it is done by the manual :)
    BTW the mechanical has been discontinued and the hydraulic one is the one that superseeds the mechanical. If one is better or worse is hard to say since both do their job well.
    And you can clearly see cracks in your belt if you have them so don't worry if you can't see any. If they are there they are literally everywhere :)
    Pro Tip: keep one belt as a spare one inside your trunk for emergency purposes. You may never need it but when the last fresh one will break for no reason at all it is still better to mount the older one to get back home safely instead of having to wait for someone to help you.
    PS: for test purposes try to run the engine before you put the fan and shroud back. That way you can continue on your work if nescessary without having to remove it again. The engine runs fine without the fan so don't worry. It is there only as a secondary cooling fan in case the electrical will fail (or the heat is massive and the electrical can't cool it down completely). Also important - keep the fan always vertical. The clutch has liquid in it and placing it horizontal may cause it to leak which may later lead to failure or even fan explosion. Once the fan explodes it will destroy pretty much everyting around itself. Including your hood if you are lucky enough. Worst case scenario of course.

    This is the only video I've been able to find that someone switched from a hydraulic tensioner back to the mechanical. It's EXACTLY what I was looking for...minus the incorrect belt routing.
    The extra bolt!!!!!!! Why doesn't anyone ever mention it???
    Thanks a ton man, this video got me back on the road

    Don't mean to talk down on your video but you ran your belt wrong. The belt is supposed to be ran underneath your idler pulley (pulley next to the alternator) so it grips the alternator better to give it a more sufficient charge.

    doesnt seem possible the lower right bolt hole is correct tensioner doesnt line up properly with the upper bolt hole unless its installed on the lower left and the the belt doesnt seem to fit over the tensioner unless its run imporperly like in the video..

    I watched your video on changing the crankshaft position sensor. That mother f***** is a b****...... I'll never ever tried to do that job again..... I wind up taking the car to a mechanic... and home boy charged me $60 dollars... to install the crankshaft position sensor... it took him 10 minutes.... I was trying to change that thing for 4 hours... and it took the mechanic 10 minutes.... Jack the car up and changed it from the bottom of the car not the top... I was trying to change it from the top and it took him 10 minutes

    Thumbs up on your video. Well explained. One doubt, though:
    When you mention using the 32mm hex wrench to loosen the fan clutch, how do you hold the clutch before you hammer? Do you use the special BMW tool 11 5 030 or is the water pump/belt tension enough to hold it? And that's a reversed thread, isn't it?
    Cheers mate!

    • @DriveMiami
      @DriveMiami  5 років тому

      I slide the wrench onto the fan clutch bolt and have the wrench standing upright. With that alone it shouldn't move. And yes it's reverse threaded.

    I have a question..I’m fairly new to this but the tensioner pulley bolt..I think it’s a T50 on my e46..I stripped it a bit but I can still tussle with it. If I take that bolt out will it be an easy change? I’m worried that if I take out the bolt will the pulley close or open and be nearly impossible to put back on

    Awesome video very informative but I have a major problem I'm trying to figure out- 2003 BMW 325i the main belt broke, twisted up and sheared off the tensioner assembly completely. All hardware(bolts washers etc) is gone. Not only that, the oil filter housing which the idler and tensioner mount up to is damaged, the aluminum has been cracked off around the bolt holes. I found a used oil filter housing, but now I'm trying to figure out if I need a mechanical or hydraulic tensioner assembly because I don't know which one the car had and I'm trying to figure what hardware I would need for it as all tensioner I find for sale come with no hardware since it's assumed you will re-use your old hardware. What can I do?

      It’s possible, the hardest thing is getting the fan clutch off, which is supposed to require a specialty wrench but I just used a rivulet skinny crescent wrench and a pry tool to keep the water pump from spinning

    The belt issue being installed properly was mentioned, but proper way is to go under the top most pulley, rest was all good. Also, if you are switching from a hydraulic to a spring tensioner, you will need a spacer to put behind the top bolt depending on which year you got because some are different. I gave a thumbs up because this was a great video and you took a lot of time to make it. Thank you!!
