Alternator almost as expensive as a voltage regulator?! I'd only wish I could buy an alternator for around 10$ . Sign me up. 😆 BTW, good video as always! 🙂

Could you do a full belt breakdown and a how to remove and replace on the mk2s. Been looking for a good video on it but I can’t find any good ones. Great video Oli!

@OlisGarage Жыл бұрын

I don’t have a mk2 (yet), but I definitely need to work on making a belt video. The belts and tensioning systems are all relatively similar between mk1 and mk2

Curious to know what made you choose this alternator over others considering you have to replace the fan and what not to make the belt fit? I don’t have the gun you use to get out the fan, and wondering if you recommend any other alternatives that might fit right off the bat?

@OlisGarage 3 ай бұрын

I thought it was going to fit right out the box. Otherwise I wouldn’t have bought it. I think it depends on who remanufactured it. You can always use a vice to hold the pulley or a large pair of pliers and a helper.

Great, as always. However I have a good alternator, but the belt snapped. Can't seem to find a link/video on how to change this belt. HELP PLEASE

Release ac compressor tension (very similar to alternator) and then remove ac belt. Install alt belt. tension ac compressor. Tension alt. Check out my rebuilding ac system video. I remove the ac compressor there. I haven’t filmed the belt replacement yet.

Hi could you make a video showing how to connect originally the fog light switch like in your mk1, I have the switch but I don't know how to connect all the pins of the switch and there's no info about it, I hope you can help me. New suscribe, keep doing mk1 content I like it soo much :)

Will we have to change the pully's length from the alternator on every alternator or is it just this specific one? If not is there a perfect fitting alternator i could buy?

@OlisGarage Жыл бұрын

I am not sure. I specifically wanted a Bosch alternator, and the two I bought didn’t have the correct pulley. Switching pulleys really isn’t hard if you have someone helping to hold. Just make the bolt that holds the pulley on nice and tight. Your local auto parts store might have an alternator with correct pulley; however I am not certain.

@chrisladouceur4093 Жыл бұрын

Looks like I may need to replace alternator on my mk2 with AC. Do the alternators typically come with the correct pulley? I’m pretty sure my old pulley needs replacing too

@OlisGarage Жыл бұрын

I thought that they did!! Apparently not always though as I found out. What is wrong with your old pulley? Just curious

@chrisladouceur4093 Жыл бұрын

@@OlisGarage I've been going through alternator belts like crazy and after trying a few things I'm pretty confident the alt. pulley is worn in. The belt is sitting pretty deep in it and has some side to side movement. Can't find a replacement pulley for a mk2 diesel with A/C for the life of me either

@OlisGarage Жыл бұрын

@@chrisladouceur4093 aaahhhh ok, sorry didn’t understand that. I *think* someone must’ve made their own replacement then at one point. You could always drill a second hole and then “connect” the holes with a grinder to make a slot to adjust. With V belts you need some adjustment capability since they get worn over time and ride farther down in the grove.

@@OlisGarage been looking more into it. Seems the diesel mk2 had a solid bar. Or at least some of them did. Used a different method for tensioning

@noxikid 4 ай бұрын

I hope you have 13.5 volts with all accessories enabled. Otherwise it is to low. And dielectic grease between contacts, seriously ? That might be the case for to low charging voltage. You may put the grease all around of already tightened contacts if you wish but I wouldn't even mess with that and jsut picked stainless nuts and washers instead.

@@mikewalters8253 I like to go straight to the battery just to eliminate any potentials of other bad grounds from the test. Vanagon is coming! Engine is in and all hooked up. It cranks like a bad from hell but just won’t quite start….so I’m trying to work through that. The engine has never run since it was a crate motor, so I’m not quite sure where the problem lies. More trouble shooting will be happening. I need to get back to editing videos again too. Tons filmed but nothing edited haha
