2010 E70 AC belt replacement
 

looking for some direction on changing the AC belt on my 2010 E70. found a reference for a gates crankshaft tool sft004 to manually turn the crankshaft to put a new belt on but cant find the tool. is this needed? is there an alternative tool to use to turn the crankshaft while in neutral? thanks for any info.

hopefully someone has some info on this service. i found many a place to get a stretch belt installation tool, pretty common actually. however, the crankshaft bolt on the E70 (M57N2) is not a standard metric socket fit. i haven't found a source for an adapter socket nor have i found a DIY reference anywhere. that is hard to believe.

any help in sorting this out is much appreciated.

I have did that with just a regular tools.M57 nose is like motorsport engines-4 bolts instead of 1 in the center.You can turn it carefully using one of them,but you need a special socket E7 or E8.

thanks for the information. i kept looking for a metal socket with four holes bored out to fit over the entire four bolt nose. did you use a stretch belt installation tool to ride the belt over and onto the pulley?

If it is original belt it will stretch and you can ride it over the pulley.Non-OEM belt may break the cords inside if you ride it over the pulley.

$17 tool

yep, got the right belt. thanks again. gonna order a set of the E sockets on amazon. have to grab some T sockets as well.

thanks. I did see this and found it identified at Bavarian auto to be applicable for the pulleys on the E70. I have seen a few diff installation tools ranging in both style and price. reviews for this particular one were good as long as the piece fit over the lip of the pulley. I'm going to pick this up as well. cheap enough.

thanks for the help

Lisle Tool for AC Belts
 

Hi PgHanna66: Did the Lisle#59370 tool referenced above "do the trick"?

Any hints or recommendation on how this tool fits the AC pulley and how you rotated the AC pulley to install the belt?

It appears to this mechanic, the KTC brand tool #A1408 better mimics the BMW 11 1 240 tool, however, KTC is sold out with no known date for restock.

Alternatively, might someone with either the BMW or KTC tool care to sell, rent, or loan the tool?

Thanks

Bump! Looking for remove/install tool for the A/C belt too,.

Best thing I did on my E60 545i was to eliminate the stretch belt by installing a belt tensioner pulley and regular belt. Now belt removal/installation is a breeze. The tensioner mounting boss exists on the front of the engine. Incidentally, my '08 4.8i X5 came with a tensioner from the factory.

Sorry to bump an old thread but it's just to say that the Lisle 59370 as posted on the first page works for removing the AC stretch belt. Did it on an E70 diesel today. The hard part was getting the belt aligned up when reinstalling.

Just FYI, there's supposed to be a special tool to move the crank but I used a ghetto method attaching the breaker bar to one of the four small bolts and forcing it clockwise (counter clockwise apparently loosens the screw). Probably not a good idea but ain't nobody got no time fo dat.
