yea its a job.
i found it easier to pull my motor and do the clutch and T-belt together.
then again, its easier for me to pull the motor because ive done it about 6 times now.
either way.
tools wise you will need a TQ wrench, and several other metric sizes between 10mm and 19mm.
u will need to remove most engine components/brackets/belts/hoses/mount etc. from that side of the motor.
to replace it you need the new belt and new tensioner at least. although i agree with biglew on the waterpump.
get the helms from
here
the h22a is a great motor, and is actually very well designed. its not hard to work on...it can be overwhelming at first though...best advice is get the helms and go from there.
