Broken belt

Just had one of my drive belts break on C 15. Although it has two belts im sure that puts alot strain on the one belt. Tried putting it on but cant get it down around the bottom. Tried putting it around fan which worked however cant figure out how it goes on pully. Looks like the fan mount slides up and down but couldnt get it to move. Any suggestions?

 

On the back of fan hub mount there should be an adjustment bolt. Look down from the top of engine and you should see it.

 

If you have two belts on the same pulley the old belt will be stretched,so it will not tighten up. If both aren't tight the loose one can come off and take out the new one.

 

So replace both at same time?

 

I would,you can see if they both tighten up.

 

Yep there it is thanks was looking right at
