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.
