pretty straightforward, I do about 4 a week. pin (m8 bolt) into flywheel locking hole, engine mount and belt covers off, aux belt off, bottom pulley off, de-tension cambelt and remove, check water pump for signs of ANY leak, replace if any trace of water/coolant (fairly common), fit new tensioner, fit belt using marks on belt and pulleys, refit lower covers, fit bottom pulley and torque, remove lock pin, tension using procedure (tension, turn over, adjust, check etc) fit upper covers, fit aux belt, fit engine mount. Done
That's not definitive BTW, but it's not far off
