Specifications

Problem:

The tensioning pulley included in the kit for the type delivered is

diferent to the one installed in the vehicle.

Cause:

According to the manufacturer, the new type of tensioning pul-

ley has to be installed in all 2.1 diesel engines when the timing

belt is due to be changed in accordance with kits referenced

above. Given the fact that the structure has been changed, clari-

ication is required on how to install or position this correctly.

Solution:

The new type is also a manual tensioning pulley which is

installed in place of the previous tensioner. After the timing belt

has been installed, the accompanying pulley is placed on the

retaining plate and screwed on together. The spring with

sleeve is no longer used (not depicted). The tension is then

adjusted as per instructions in the past.

(e.g.: BTT Hz: 104 Hz +/- 5)
