as you already know mate lol.
Fitment;
- Jack car up, secure on axle stands
- Disconnect the batteries positive lead
- Remove airbox and upper hosing
- Youll then see it down underneath the inlet manifold, going into the gearbox with three wires going to it.
- There are three bolts to undo, two you undo from above, they go through the gearbox casing into the motor housing, 13mm heads I believe.
- The third is only really available from below, and goes through the motor casing into the gearbox casing right down near the big bulge at the bottom of the gearbox the shafts go into (the diff).
- When these are undone its a case of moving the motor about so you can see the two electric terminals and three wires on top, which is at the far end of the motor when its fitted. Note which cable goes to where. Undo the bolts on these (carefully, they love to snap off inside). Remove the wires, followed by the old motor
- Fit the new motor in reverse, making sure you connect the correct cables to their terminals.
- Before fitting the last, lower, slightly cuntish bolt fire the engine up and make sure she fires up. Then ft the last bolt and reconnect the positive battery lead.
