Tightening the fan belt of C250D (1994)
 

Hello friends my first post ...

I have a 1994 C250 D just notice the fan belt is lose and as i do most of my repairs myself .. just wanted to know how to tighten the fan belt ...?

I searched a lot and could not find any thing that will tighten the belt. The tensioner spring and the small shock are fine.

Is there any way to tighten the belt like in other cars eg( AC compresser or Altenator..)

Any help is good help

Cheers

Drive belt tension
 

Hi Mastero,
the spring should provide all the tension the belt needs. Is the short shocker type thing maybe siezed?. You can release the tension to check it by removing the bolt that passes through the tensioner assy & a lug on the cyl.head, gently releasing it using a bar into the hole in the top of the tensioner. Are you sure you have the correct length of belt fitted?. The tensioner pivot can wear, allowing the roller to sit slightly skewed.

Hello peter,

The small shock is fine all shock bushings are fine.

The spring on the right side had snaped hence i changed it and after putting it back i found the belt running lose. ( The tension spring is fixed properly 100% sure the shock is fine 100% sure the tensioner roller is fine not skewed)

I wanted to know is there any other way of setting the belt like is there any adjustment in the pully ?

Finally the belt looks fine no cracks or any sign of wear and tear.

cheers
