Rob’s (Firestarter) 4.2 threw up a little problem the other day which I attended to because he had to got and fight fires.
The alternator warning light would not go off at idle. The strange thing about it was that it seems linked to the oil level and "water in fuel filter” warning lights which all came on together. Now I don’t know if any of you have done one of these but it really isn’t in the most accessible place - its right down the back of the engine. I worked off ramps as I didn’t see much benefit in being over the pit. It just makes it hard to reach from underneath as well as on top - hey ho. The bottom dirt shield needs to come off and then you can get at the drive belt. The tensioner is easy to get at. De-tension the belt and slide it off then undo the tensioner and remove it.
There is a bolt at the bottom which is the equivalent of a tensioning bolt and a big one through the top. That big one is tapered and after slackening, it is withdrawn part way back. My immediate thought was that it would hit the bulkhead and therefor require the engine out but it involves an ingenious solution. The bolt is tapered and only needs pulling back about 50mm. Ofter that. the reduced diameter allows it to come out sideways and the alternator is free. Ok, I’m being kind here and saving you a lot of head scratching because although it lives in quite a big cavity, there is no obvious way to get it out. Well as Yaz would say, the only way is up. It will not come down. The only trouble is, there is quite a lot of clutter and brackets to come off at the top. The intercooler and the engine cover, then there are brackets for the turbo and the A/C pipes.
When they are all off it will come up but there is no room for the oily alternator and a hand so I ended up button string through the mounting hole and hoisting it up. Here is the offending instrument;
They cost in the order of £145 yo £165 from a decent factor. ECP want between 188 and 300 with a Denso coming out at 265.
The alternator can be seen on the attached pdf. There is no point me attaching the removal instructions, I suspect it refers to a removed engine because it just says “remove the alternator”!
