I am about to undertake a water pump, timing belt and tensioner and idler roller change (and auxillary belt and associated rollers too!
) and would like to ask for some clarification.I have done all my own belt changes on every car i ever owned so far with no real hassle, but I am confused following the reading of the relevant "Haynes" manual for my slightly newer car!!!
There is no reference made to any Tension for the timing belt for the 1.4 HDi, only 2.0 HDi!!,
am i right to assume PSA have taken all the guesswork out of tensioning the 1.4 HDi and fact made it an absolute doddle to change with no need of a tension guage 
? the only paragraph i can see that would give any tension has the following advice:-Slacken the tensioner pulley bolt and using blah, blah hex key, rotate the tensioner anti clockwise, which moves the index arm clockwise, until the index arm is aligned.remove crankshaft and camshaft timing pins blah, blah, and rotate engine 10 complete revolutions, refit the crankshaft and camshaft timing pins .
check blah the index arm is still aligned between the edges of the area, if not remove belt and begin refitting process again.
remainder of refitting is a reversal removal etc blah.
Could I ask to anyone out there in FCF land if they have ever changed a 2004 1.4 HDi timing belt and this tensioning method is "correct" with no need for tension gauges etc.
Thank you Garry
So gone are the days for tension gauges then, as long as the engine rotates X number of times after setup and still lines up with notch and all timing pins line up and correspond job done and no need for Mr "Gates" and his belt tension gauge to check my handiwork
