Chaning the belt and tensioner: The Britpart HP fuel pump drive belt kit (part number 1324390) fitted here, comprises the new belt, new tensioner and a new bolt.
The quickest approach for this job is by laying over the engine after removing a few parts that obstruct the reach to the drive belt (location arrowed).
Closer in, battery’s removed and EGR coolant pipe (silver) and engine harness are released and moved aside. (Top of belt casing just visible, arrowed.)
From here on, working from the engine bay relies on skill, practice, mirrors and feel. So here’s a vehicle with the body off, to show what happens.
Looking from the rear, we can clearly see the drive belt and pulleys at the back of the engine after unclipping the belt casing’s cover.
As in our earlier diagram, the camshaft pulley is on the left here, tensioner pulley in the centre, and fuel pump pulley on the right.
A 10mm socket and wrench can be slid down the back of the engine to release the tensioner’s fixing bolt in the normal thread direction.
If working from the front of the engine, final removal of the tensioner pulley and its bolt needs a steady hand, but is easy with body off.
The old drive belt can then be eased off over the two remaining pulleys and withdrawn into the engine bay to be discarded after removal.
The new belt is fitted over the pulleys, noting any direction arrows. The pulleys turn anti-clockwise as seen from the rear of the engine.
Backplate of the tensioner pulley (left) has a tongue which engages into the back of the pulley casing. Pin on front (right) locks spring until fully fitted
Tensioner pulley is installed, ensuring the tongue at the back of the tensioner engages in the recess in the casing seen here behind the pulleys.
The tensioner pulley’s new bolt is tightened to the specified torque (currently 25Nm). Note, its locking pin stays in during installation.
After checking the belt is aligned and seated on the pulleys, the securing pin can be removed, allowing the pulley to apply tension to the belt.
Refit parts if working over the engine and replenish coolant if EGR coolant pipe was disconnected. Or, as in our case here, refit the body.
