P2 Timing belt tensioning procedure PSA, ENGINE NUMBER BREAK

[abscate]

Learned this today, researching. On P2 cars, based on engine number, the direction fir tensioning the tim8ng belt changes.

From Alldata

Tighten the timing belt:
There are two variants of the belt tensioner.
From engine number 3188688 the eccentric must be turned anticlockwise to tighten the belt.
From engine number 3188689 the eccentric must be turned clockwise to tension the belt.
turn the crankshaft clockwise carefully until the camshaft belt is tensioned. The belt should be tight between the intake camshaft pulley, idler pulley and crankshaft.
hold the center screw on the belt tensioner in position and turn the eccentric on the belt tensioner clockwise/anticlockwise, depending on the variant, until the tensioner's needle passes the marked position.
Then turn the eccentric back so that the indicator reaches the marked position in the center of the window.
Secure the eccentric and tighten the center screw to 20 Nm .
Check that the needle is in the correct position.

Of course, one wonders if you have a P2 now, how do you confirm you have the right tensioner?

From the FCP site, it looks like this was a mid 2004 change , FYI

Yes. this is interesting (and for me, new) information. I'm surprised this wasn't better known, especially amongst this knowledgeable group.

Most of us here are normal people with one or two cars, so it’s a small subset of those owning a 2003-2004: and 2004-2007 and doing DIY timing belts on both who would catch this.

But,that’s why we are here……

I did my 2005 timing belt back in 2014 and just ordered parts from FCP
