How do you fit an alternator on your vauxhall cors 1.7 dti?

Answer 1

Its a pain! If you can afford to get it done at a garage, do that (obviously) but if not...

Jack up the left driver side wheel and put bricks under the chassis, it needs to be about 4 bricks high but depends how big your head is. Open the bonnet and disconnect the battery, drain the radiator fluid and disconnect the pipe that comes from the engine block (for radiator fluid). Disconnect the pipe that comes from the turbo that goes into the intercooler, plug the turbo exit with something clean (a rag) - that's the pipe all the way round from the turbo to the intercooler, you need to undo the 3 screws that hold the bumper on at the top to get your arm in.

All that is necessary to give you space to get the thing out. You also need to remove the bit of plastic in the front right of the engine bay that's forward from the arch, this is the only gap you can get it out from. Now to getting it out.

Assuming your doing the steering pump at the same time, remove the pipes connected to the back of the alternator (4 in total, one vacuum easy to get off and 3 other not so easy AND THEY CONTAIN OIL, you will lose some). Also remove the wire held in by some plastic bolt and the electrical connector. There is a bolt at the top that you can see and a long bolt at the bottom you can see one end of, take them out.

It should now slide out that gap at the bottom where the plastic you removed was, do this in reverse for fitting the new one!

Remember to re-fill the radiator and top-up oil.
