Water pump / timing belt tension tool

[Rodd1s]

My Lanos' engine is slowly creeping up toward that 50,000 mile mark still on the original cam belt... when it comes to the tension wrench/tool, does it have to be the specific one as mentioned in the 'How-to' section, or will a generic GM one work, like this: http://cgi.ebay.co.uk/GM-VAUXHALL-WATER ... 1982wt_939

i think the tool in the pic will not be a problem

my mechanic uses a standard issue 42mm wrench to do the job but he has to completly remove the back side of the timing belt casing

if you're replacing the pump or the O-ring, yes the rear timing cover will have to come off, but if it's just to release tension of the belt, the rear cover doesn't have to come off. also if all else fail and the tool doesn't fit, use a grinder. i've just been making ends meet using alans to losen the 3 bolts, and vise grips to rotate it. a BIG pain if u try to just smash the auto tensioner.
