Hans,
Place rear of Vanagon on jack stands, disconnect Subaru charcoal
filter hoses, Remove muffler clamps, remove exhaust (header, cat and
muffler in one piece, Kennedy header), place jack underneath aft
section of transmission, near flywheel, remove engine mount crossbar
(Volkswagen), lower engine with everything attached(coolant, fuel,
wiring etc) maybe 10", bend back heat shield, remove smallcar mounts
(cross section, with motor mounts attached to it), remove timing belt
covers, loosen tensioner pulley, remove timing belt tensioner,
contract tensioner in vise (slowly, I take no less than 5 min in a
vise, then insert allen key as pin to hold it), align cams and crank,
install timing belt (easier now, since it will have stretched a bit),
install tensioner pulley (don't tighten bolt yet), recheck alignment
marks, maybe rotate engine (without tensioner), slide in tensioner,
install tensioner and bolts for it without tightening, recheck
alignment marks, leverage tensioner to all the way left with
screwdriver, tighten tensioner bolts, recheck alignment marks, torque
both tensioner bolts and tensioner pulley bolt, rotate engine,
recheck alignment on all marks after rotation of engine, remove pin
on tensioner, rotate engine one last time, recheck timing alignment,
reassemble.
Interference type engine (2.5 I believe) will require more care...
get ready to rumble.
Cheers
Matthias
