BMW N52 Drive belt , Tensioner , Idler Pulley Removal & Replacement

[@mkm7962]

Something to consider on my new motor I've just purchased, along with a load of other little minor jobs. Don't seem to have much room but I have got those small hands and wrists that can get everywhere. Good video Dean.

Great vid doc, about to do this job aswell after oil filter housing gasket leak as you recommended.

Hi, thanks a lot for the video! I have a question about the dynamometric wrench, i dont have one. Do you think i should get this job done in the garage who has that tool? Or is it ok to tighten that bolt by hand until we fill thats is enough?

[@patricklee5524]

Thanks for another vid doc, going to get them done on my car now👍

I've done the same thing on my N62 545i and it just about the same thing. Easy peasy.

[@BMWDoctor]

Very easy 😀 need to get my sons doing the next ones as I had enough of doing these. There so easy anyone can do it with no experience

I remember when i first bought my n52 off some guy in chicago. I dont know how long the guy had it like this until i got and and then i drove it like that for like 4 months but he still had the pin in the tensioner😂

[@aaronobrien7821]

same process as the bmw z4 3.0 si e85?

Hey BMW Doctor, how do you change the AC eleasti-belt with out the special BMW tool on an E60 535D M57 engine. Is it possible?

[@BMWDoctor]

Special tool ? I have done them many times with no special tools

[@SamanthaGreen-nt3rw]

@@BMWDoctor According to ISTA you need a tool to stretch the belt from the AC pulley on to the crankshaft pulley

[@cryptocrate1000]

where do I find the bolts torque specs for this engine?

Recently subscribed to your informative channel. How does one ask a question that others can't seem to cure. I am a 47yr retired auto/truck mechanic and the fact that my 2015 428i Grand coupe sport N20 will on occasion have the water pump stay on and run down the battery so far that charging or jumping it is the only solution. I just recently had this occurrence twice. Any help in this area or how to call/text would be greatly appreciated..

[@juniorgeeroms8018]

New waterpump is solution

[@IccDani]

i did this job yesterday. but now everytime i hold the brake pedal when i start the car, the rpms go wild.

Hello, i have changed my Belt and tensioner and the other pulley, but after 10.000km saw i have rubber dust on the engine block, should i be concerned or its normal?

[@BMWDoctor]

Yikes what kind of dust ? If it’s black dust that means your belt is shredding itself which means something ain’t right 😬 could be your tensioner way too tight or the belt is not on properly or a pulley is not spinning correctly.

@@BMWDoctor well yes, black, but it stoped at some point, will have to clean it and see
