Belt Drive Belt tensioner Climate Compressor missing
 
1 Attachment(s)
Hello,

I want to change all the belt of my car because of 72000 milage and preventive maintenance.
By this way I found out that the belt tensioner for the climate compressor is missing.
It is a second hand car and I don't know what the pre owner did. When I look at the mounting point for the tensioner, then it look like that there was never a bolt in.
I dont know how they got the belt on.

So it look like that I have to buy the tensioner, :tsk:

I am pretty sure there is no tensioner on the A/C compressor belt.

This thread has a .PDF with the instructions for both belts.

Thanks for the link, when I look to the second pdf down the last picture I can see the belt tensioner, maybe for the model later they installed it.

I think BMW re-uses pictures from different cars in the TIS. The first and second PDF look like completely different motors. Maybe send brown370 a PM since it looks like he has changed these belts a few times.

The V-Belts has a tensioner and the A/C Compressor does not. You have to pull the belt off with a rag while turning the crank. You have to use a special tool to stretch the new belt on.

You will need a sepentine belt tool w/ a large Torx socket T-55. To remove the sepentine belt first (lest than 10 minutes) Take a picture of the belt before removing it so you know how it goes back on.
Jack up the car and remove the front underbody cover. You use a towel to remove the A/C compressor belt while turning the crank/engine. One you remove the old A/C belt, put the new belt over the crank first, and then install it on the bottom of the A/C compressor and install the tool pictured on the A/C compressor pulley. Turn the crank clockwise keeping the belt tight and the tool will pop the belt on. I had to do it twice because the belt ribs did not line up the first time.

Thanks for the help, I postpone it in the moment. After changin of the O-Ring for the temp-sensor and changing of transmission oil, I need a rest. :-) Will do that then later, but it i slik u wrote.

AC belt install tool
 
I am fighting installation of the AC belt. I made a tool to hold the belt and turn the crank over similar to the tool shown in the prior post. Even with my home made tool I am having difficulty.
I need to break down and buy the proper BMW tool to install the AC belt. I cannot find the part number for the AC belt installation tool.
Does anyone know the part number for this tool or where to find it?

daf290 08-17-2012 06:31 PM

Found Part number
 
Sorry, I found the part number of 64 1 040 but I cannot see any of the online suppliers that list this part number. I guess I may need to try to special order.
Thanks

Hey guys. I know this is an old thread, but I thought I would add a little update. The belts used by BMW are manufactured by ContiTech so you can replace them with either BMW branded belts or the Continental ContiTech ones.

I know this is an old thread and you 6er's may already have this info someplace, but while searching I ran across this thread & thought I'd share.
These are the parts I used on my N62TU to upgrade with an A/C belt with tensioner.

Spongee Belt
 
The spongee belts are now quite common in many cars.
These belts are designed to be used without tensioners.
They are a bit different to get on and off but now that I have done a few, I kind of like them.
I would have no reason to change to a belt with tensioner.

Have you used this tool on BMW vehicles?

Napa Tool
 
No I have not seen this one. Looks like a great tool if it works as shown.
I bought the actual BMW tool to install on my 650 and a generic over the belt and attach to the pulley tool for my wifes Lincoln. I especially like that this has a removal tool as I do not like cutting the old belt off.
Good find, maybe someone else can use this on BMW.

Nice, I love the looks of this tool. Next time I'm changing belts I will get one of these.

Search for "Private Brand 70990" if you want a set. Found it for $26 here.

No tool
 
Old thread, but I'll add my two cents.
2006 650i.

I'm a relative newbie at this, but I was able to just work the belt off and later back onto the pulley without the tool.

Getting it off was easier than putting it on. (but certainly not actually easy) - Working from the top, I ratcheted the crank clockwise and pulled the bottom of the belt towards the front of the car as it rode onto the A/C pulley and then finally off of it completely.

Putting back on I reversed this, and it was slightly easier. I rotated the crank counterclockwise so I could guide the top of the belt over the AC pulley with my left hand. After a revolution, the belt was around the pulley.

It seems to have stayed on no problem since then.

Newbie tip: Put your manual transmission in neutral first.

I just installed the stretch belt last weekend (the old one snapped and vanished... Probably from slippage from the vacuum pump oil leak that has since been fixed). First, I struggled and cursed and tried to turn the crank manually forcing it on to the pulleys... It is pretty much impossible. I bought this tool: http://www.ebay.com/itm/181903809053...%3AMEBIDX%3AIT which is pretty much an aftermarket, less expensive version of the BMW tool. (want to buy mine?) lol

I removed two bolts holding on the bracket for some cooling tubes that were in the way of the compressor pulley so I could push it out of the way and attach the clamp at the lower portion of the pulley. With tthe belt loosely on the Compressor pulley and Completely on track of the main crank pulley I went under the car and pulled the belt counterclockwise over the compressor pully as my girlfriend rotated the crank clockwise and the pretty much snapped right on. This is a two-person job and you will 100% need the tool, if you don't want to play games with the crankshaft pulley screws-half-on trick.
