In the middle of doing mine me self after work, done 3hrs on it me self so far as i'm not as good as a pro and didn't have all the right tools at first. Got the new water pump and housing off and switched over, belts off,vibration damper pulley thing off,, had to get new bolts though, them old ones were well and truly in and mashed up by the time I got em out, and seriously ,the 1.9d/1.9td is super easy to do your self.
Really the 1.9 should be the cheapest cambelt change out of the range of T4 engines, as its one belt for the fuel pump and cambelt.
cambelt + tensioner (no bolt needed for as tensioner sits on a captive nut and thread) £35 VAG KIT I got from fleabay.
new bottom pulley bolts £2 TPS
waterpump + stat (as mentioned its not tensioned on cambelt, just doing as i'm down there anyway) £27 + £6 GSF
bottom sprocket bolt and check for keyway wear. £ 3.50 BRICKWERKS
I asked when at my local garage for this in case I didn't have the time and they said, all in £190, with the parts, how ever I fancied the challenge and wanted to do more than just a belt and tipex. Granted I needed some extra tools.
I am stuck on my other 2.4d van though as some bugger has cross threaded the cambelt tensioner bolt and need to figure out if i can helicoil or re-tap it or what, i dunno, so for now, that van is a garden plant pot LOL:
