- Location of bolts to remove alternator or just belts. Aleady took a few bits off to make if easier to get to alternator. .the hidden torx bolt behind a plastic cap which is the belt tensioner
The steps are like this:
1. disconnect the battery negative or positive
2. unbolt the hex nut for positive behind the alternator and move the wire out of the way
3. disconnect the other connector too
4. remove the plastic cap on the the pulley, and then, with a torx bit, rotate counterclockwise to lose it
5. move the belt out of the way, but make sure you take a photo of it so you can put it back the same way
6. remove the plastic cap on the other pulley (it is located next to the previous one, on the right), and with a hex bit rotate counterclockwise. this one is a static pulley so it will just come off with the bolt. this pulley hides behind it one of the bolts that hold the alternator
7. now you can start removing the alternator bolts. most of the times it has 2 bolts, a shorter one at the top and a longer one at the bottom
8. after you manage to remove the 2 bolts that hold the alternator, you need to make some room in order to get it out. the easiest way is by removing the the top end of the EGR hose. just unclamp it and pull it towards you
9. now you can remove the alternator but you should spray some wd40 around the bolts areas because even if you removed it, it will kind of remain stuck in there and this will make your job easier
Legend !! Much appreciated
Ah there's a bloody cap on the tensioner pulley hiding the torx bolt?! Thank you sir for uploading this! 👏
Nice man,you solve my problem
Skipping a lot of steps there mate. Not possible to take it out like that. Not seeing you finish the job and have the thing out of the motor compartment. It's definitely not as simple as you make it appear. Unfortunately. Did you get the car incomplete or do you just drive it incomplete?
Thank you Thank you.
ALTERNATOR is the weakest and most expensive car generator, made only to oppose the high mechanical resistance it takes from the engine, which translates into fuel consumption. The stator winding is made in such a way as to output three-phase current on which a Expensive and bad diode bridge rectifies it by making it direct current. The efficiency of this shift is of maximum 53%. It consumes a lot, it produces little and it has many expensive components that go quickly to make the drivers for sale. This mess was made especially in the purpose of consuming more gasoline and to sell components that you do not find in the old dynamos. On this site you will find videos showing the old dynamos, used now in some countries, which had a dual role: starter and after it started the engine became a generator. The mechanical force it consumes from the engine was small, it was robust, without straightening axles and it burned hard. dynamo if instead of the aluminum housing in which the bendix is located, a bearing cap is mounted in which to enter the rotor shaft. The stator coil must be decoupled from coal and coupled separately to become excitation coils controlled with the load relay. the rotor, the starter spins.If the sprocket of the bendix is fixed on the shaft not to slip, then it will always remain on the crown of the flywheel, and after the engine has started the sprocket takes over the movement of the motor and reverses the rotor that will produce current by charging the battery. some old model cars, this was done with a transmission belt that came on the flywheel and on the starter - generator.With a single good, robust, reliable and high efficiency device, two maneuvers were performed. Now there are two components that do the same. maneuvers but with higher costs. Question: why? I wrote above. You can find other hidden motivations. Success.
Hi Paul need your help for a minute mate could you tell me what was the size of the torx bit that you used on tensioner
the last 16mil bolt, the one the pulley attached too, partnumber on it? mine is missing
cheers .... I'm a 1st timer ,
Ciao la torx da quanto è?
need a better camera man mate
