That's one of the more comprehensive guides I've seen... :thumbs:
however...
Although it does say to loosen off both cam pulleys (which is good news) it doesn't explain why... when the pin is pulled out of the tensioner, it's critical that the pulleys are finger tight so the whole system is tensioned properly all the way round... A lot of mechanics are just not getting this bit right at all, if it's not correctly tensioned you can literally just pull the belt off the pulleys with your fingers as I have on many now..
With regards to the 'kick back' plate on the tensioner..it does mention (as per the Gates guide) that the setting bolt be tightened after the tension is applied to the belt...again, a simple task which many mechanics are making a complete balls off lol.. when done correctly, the kick back plate sits about 3mm away from the tensioner so that when the engine is turned off or you hit the rev limiter the tension in the belt isn't reduced by a severe amount...
It also makes no mention of the 'ideal' way of doing it (IMO) which is to lock up the flywheel on the other side of the crank.. if you lock up the flywheel at TDC then achieving the 40nm + 90deg is a lot more achievable by hand... (without breaking the TDC pin)
how anyone is going achieve this with that fabricated holding tool with the crank freely turning round is completely beyond me...whether your on a ramp or stands it sounds like a nightmare unless your one strong M***** F***** :lol:
With the engine in the car most garages will simply blast the bottom stretch bolt on with a high powered gun...
It's a hell of a lot easier to make a tidy job of it with the engine out IMO.. plus you can clean down the side of the engine and make a more pukka job of it..

ps... one more little tip...holding the VCT cam bar by hand on a short 20mm spanner is really quite awkward...ideally when torqueing up the VCT bolt to 105nm you could really do with a good long 20mm spanner....I do this with the cam bar in place, resisting the movement with the spanner, but you do risk breaking the ends of the cam bar using this method... :idea:
