marinabrid Posted December 9, 2005 Report Posted December 9, 2005 ;) sorry to appear dumb but this aux belt tensioner.on the tis disc it gives clear instructions on removeing the thing on the pd unit injector engine but nothing on the earlier tdi afn engine. is it the same thing ?masked maurader said there be just one tensioner on the top of the belt but whats the one at the bottom with a bolt that you use to release tension ive read about on here and on the tis disc, it says remove power streering belt and relase tensioner with one bolt.just to clear up as im now getting mad...does the afn 110 tdi engine have the auto tensioner at the top and if so do ypou just remove bolts and change it when it sqweeks ? ive looked at the tis pictures on belt change and it shows a pully at the top on its own , but on the pd engine it shows the pully and 3 bolts and gives instructios how to do the job.can someone just clarify the job thanks very muchy Quote
seatkid Posted December 9, 2005 Report Posted December 9, 2005 There seems to be two versions depending on whether your engine has a automatic tensioner or not. If the aux drive belt also drives the power steering pump then it has an automatic tensioner... Pump Assembly - Power Steering (CD-V6 and Diesel) - Remove And Install (13 434 0) Remove the drive belt. 1 Rotate the belt tensioner in a clockwise direction.2 Remove the belt and release the belt tensioner. Pic is view from below - the tensioner is on top continued in next post.... Quote
seatkid Posted December 9, 2005 Report Posted December 9, 2005 Early diesels have a different tensioner (not sure if its automatic ;) ) and have a seperate belt for the PAS pump. In this case you slacken the power steering pump (3 bolts on 90bhp, 2 bolts on 110bhp) and remove the PAS belt first. Then detension and remove the drive belt (one bolt) see pic below Quote
marinabrid Posted December 9, 2005 Author Report Posted December 9, 2005 i got the seperate ps belt. i see no instructions for tensioner changing in the tis on this engine or is it somewhere else ? is it just a quick job or more complex to change this type of tensioner ? many thanks Quote
seatkid Posted December 9, 2005 Report Posted December 9, 2005 I think this tensioner is manual, it is internal and dont think its changeable. If the aux belt is just squeaking, try tightening with that one bolt.... Quote
Masked Marauder Posted December 9, 2005 Report Posted December 9, 2005 To change the tensioner pulley? You pop the belt off, prise the cover off the back of the tensioner pulley and unbolt. Replace in reverse of above. If you buy the new pulley all will become clear. They are about Quote
Masked Marauder Posted December 9, 2005 Report Posted December 9, 2005 The PAS belt drives the water pump too btw, so don't go over tightening it, you will overload the rear bush on the water pump. Quote
