you need a torx socket set, a 24mm spanner and a torque wrench + the usual sockets & spanners
if you jack the engine up a socket will fit the 3 engine mount bolts, one is hidden underneath
then if you lower the engine right down, the long water pump bolt should just slide out :roll:
if it won't come out remove the chain cover with the bolt still in place 🙂
you can either loosen the exhaust - 3 bolts so not hard, or leave it in place dunno..
first job to do is loosen the crank pulley bolt, get someone to put the car into fifth gear and press the brake pedal, then try undoing the bolt with a long bar - it's very very tight :?
