Thread: V Belt to Serpentine

You will have to change loads of smaller things like the air cond hoses, oil cooler hoses, power steering pump connections, alternator wiring, injection temp sensor plugs etc. You'll save yourself a lot of headaches by just using the front housings and inlet manifold off the 3.5 at the cost of a couple of gaskets.

Thanks Bee Utey, i knew it would not be simple, all good ill just change it all over, thanks

Heres another Stupid question, so i cant use the Inlet Manifold and EFI from the 3.9 and just plug My MAF into it?? the engine if from a 96 D1 btw..

Look, as I said before, either mod your wiring to reach the sensors etc in different positions on the 3.9 or just swap the entire manifold. In any case, inlet gaskets don't last forever and are worth changing, and you can fit the 3.9 injectors to the 3.5 manifold if you choose.

Just trying to get my head around things I have limited knowledge about, thats all.

I converted my 3.5 flapper EFI v belt Rangie to Disco serpentine belt 3.9. I used all the Disco EFI as well. No big deal. There is some mucking around with A/C regas and oil cooler hoses, but I think it is worth the effort. The Rover v belt set up is atrocious.

Ok so if I get the oil cooler hoses from the doner vehicle will they work or do they need to be made up, bare in mind im probably going to use the trans that was mated to the 3.9 as well as im getting it all in one package. Basically, when its done it will be a 93 pre update witk a complete 96 drivetrain, I would like to use the serpentine setup but happy to keep it v belt if thats easier, also I will be getting the ECU as well, will that plug straight in or are the looms different?

I agree with BigJon, the V-belts system is terrible. It'd be worth changing to serpentine, it is so much better.
