I have a 1999 VW Jetta GLS 4 cylinder 2.0liter SOHC New Body Style. My Alternator died, according to the technician at the VW Dealer. The electrical system diagnostics done by the tech indicated that the alternator was producing only 10amps and should be producing something like 14 amps. Backing up a bit; during the morning of the failure, my battery light went on. Later that night, I noticed that all interior lighting (including instrument dash-board lights) went dim. Additionally, the brake, ABS, airbag, etc. lights went off and a beeping noise occured. Long story short, my car started to sputter and eventually died on the highway. When I tried to start the car, the engine would barely turn over and the instrumentation lights flickered rapidly. I called around and found that PEPBoys or Advanced Auto Parts had Bosch alternators that fit my car for like $250. Bosch alternators at VW Dealer Parts Department costs $500 minimum. I'm not sure if it's the same one, but the VW guy on the phone said "Bosch". You do your own reasearch. Labor is 1.5 hours. Total from VW Dealer was around $750.00. I'd like to hear the experience of others as well.
You should be able to remove the alternator bracket, on your 1995 Jetta, by removing the three retaining bolts. The bracket should easily come off.
Begin by removing the belt from your 1994 VW Jetta alternator. Remove the alternator wiring harness. Remove the alternator retaining bolts.
Remove the 1999 VW Jetta alternator wiring harness. Remove the alternator belt. Remove the alternator retaining bolts. Reverse the process to install your new alternator.
You will need to bolt the alternator into your 2001 VW Jetta engine. Connect the wiring harness to the back of the alternator. Put the serpentine belt on to the alternator. Tighten the belt.
Remove the wiring harness from the back of your 1993 VW Jetta alternator. Remove the three alternator retaining bolts. Remove the alternator belt. Reverse the process to install your new alternator.
You will need to remove the belt from your 2002 VW Jetta alternator. Remove the wiring harness from the back of the alternator. Remove the alternator retaining bolts. Reverse the process to install the new alternator.
You will need to attach the alternator, with the retaining bolts, to your 1999 VW Jetta engine. Attached the wiring harness to the alternator. Put the serpentine belt on to the alternator. Attached the battery cables.
There is no fuse for the alternator.
have you checked the alternator??? that's the first thing that comes to my mind if your battery is being drained
Begin by loosen the tensioner bolt. Slide the alternator to the left and remove the belt. Remove the wiring harness from the back of the alternator. Remove the alternator retaining bolts.
You have to remove the power steering belt and the AC belt to remove the alternator belt.
you might need a new alternator. thas what happend to mine. Did any dash board lights come on and the radio start changing by itself?
Loosen the tensioner pulley. The alternator belt will come loose. Remove the alternator belt. Put the new alternator belt on and tighten the tensioner pulley.
changing the bulb
A 1999 Volkswagen Jetta's alternator is located on the front of the engine. To remove it the mounting bolts, belt, and bracket must be removed. Once taken off the engine the alternator should be directly tested to see if it is indeed the problem.
you need to reprogram your radio when the battery has been disconnected - see owners manual
A rebuilt alternator is around $90-250 USD according to the year of the unit and whether you have A/C or not. Figure 1 hour to r&r the unit and test at $75 /hr.
Yes, a good idea.
front side of engine near the alternator
Hi, if you are still looking. gas engine Jetta: remove negative battery cable. remove positive cable on alternator. remove blue wire on alternator. Loosen and remove mounting bracket (on top of alternator) be careful not to lose any of this bolt (very hard to find replacements). Remove alternator belt. REmove lower mounting bolt. Remove from engine. Reverse to install. All done. diesel Jetta: mounting bracket is on the bottom and engine mount is on the top. that's the only difference. same procedure. have fun!
I replaced mine the other day- it is under/behind the alternator.
Either Your Battery Is Dead or You Have a Bad Alternator
Look at the front of the bracket underneath of you alternator, you will see a bolt that connects to the back of the pulley below the alternator itself. That will dial in/out your alternator and then you can tighten down the nut that holds the pulley in place. WHile it is true the tensioner is located on the top of the alternator with a dial type ratchet system, I have not had an 89-90 Jetta where this works. Usually you have to tension it with a bar of some sort prying against another pce of the engine.
Your battery is bad, your alternator is bad or you have a wiring problem.
You need a 17mm wrench. All you need to do is rotate the tensioner pulley near the alternator and slide the new belt on. It is quite simple. I have a 1994 jetta 2.0l which I have done lots of work on, too much to list.
