Alternator interchange
 
Hello, I'm getting conflicting answers to if a earlier D2 (99-02) alternator will fit & work in my 04. Anyone know for positive? And thank y'all ahead of time

abran 08-19-2017 01:24 PM

Yes, direct fit. Positive

kenk 08-19-2017 02:03 PM

thank you

99-02 Range Rover 150AMP out of a Bosch setup is also 100% compatible.

I've never heard that the alternators were not compatible, but AB shows different part numbers for the '99-'02 and the '03-'04. I wonder why. Anybody know?

Good to know. What is the amperage on a stock D2 alternator?

different amps. 03/04 is lower than earlier.

kenk 08-19-2017 08:08 PM

Cool, so buying an '01 would be an upgrade in amperage

That's what was confusing me. AutoZone showed different part numbers, but rockauto.com showed the same. Unfortunately, the only one remotely near me in a wrecking yard is an '01. Well, not unfortunately anymore, lol

99-02 D2/Range Rover used Bosch 130/150amp alternators. While 03-04 D2's used Valeo Alternators which I believe are still 130amp units.

I have had good luck pulling alternators from "wrecked" D2/Range Rovers that appeared to be driving before the accident. Pulling one from a D2/Range Rover that looks clean is more of a 50/50 chance, but 25.00 isn't a very expensive gamble.

I'm 99% sure the 03/04 is 120.

They probably are, I just never find the amp rating on the Valeo units.

Yes,only a small gamble. Even bigger reason is no one could have a new one in for a few days (had to happen on a weekend) Of course, Ft Myers does have a Land Rover dealer. But even if they had one in stock, it'd probably cost more than my cars worth, lol

03-04 as shown above were indeed the Valeo 120 amp model but when mine died on me earlier this year I selected the Bosch 150 amp model from Pep Boys over the 120 Valeo and it was a direct fit and has been running fine ever since.

kenk 08-21-2017 02:48 PM

Well, I scored one off an '00 for $19 and change at a UPull it. The only thing different is the big main cable attachment was not in the same spot. It just required a little cable rerouting and good as new.

We just replaced an alternator on our '04 D2. The one we pulled was a 130amp.

AutoZone told us it was an Voltage Regulator. We pulled it, replaced the VR and still had an idiot light for lack of charge when reinstalled.

I replaced the 130amp with a 150amp after several positive threads were received here on the forums. Thus far, no issues...

This is a great place for the best answers on things LR...without hesitation.:bow:

Cheers mate,
