serpentine / pre serpentine ! Whats the difference ?????

[pil2255]

Hi

Sorry if this a silly question, I have a 1995 4.0 Chim. I dont know if its a serpentine or pre serpentine engine (would guess pre serpentine as its an early car)

What is the difference between the 2 types and is one dramatically better that the other ??

If anyone can give me the low down on these engines i would be greatful

Thanks

Mike

The easiest way to tell is to look at the accessory belt(s), if you've got 1 wide one for all accessories then you've got a serpentine, it you have more than one skinny one its a pre-serp.

Thanks for the heads up on telling which one i have in my car, is there any technical / performance / reliability differences between them ???

Cheers

Much of a sameness really Serp as crankshaft driven oil pump(supposed to be more efficient)Pre-Serp as camshaft driven oil pump along with neater wiring loom and better cooling system plumbing there are some more points but that's pretty much it

Gearboxes differ too. 'Serpentine' engines normally have the T5.

And late pre-serps have T5's I thought we was just talking engines though

Rover box reverse is up next to first gear

If its a Borg warner T5 its down alongside fifth

Just to confuse things a bit I have a cross bolted 4.6 but with a pre-serp fan/pulley arrangement!

When I got my first Chimaera, 95, the factory had scribbled a new reverse position in the handbook diagram of the gear knob.

Yep mines a late pre-serp ('94) with T5 box. So door release knob in its own little pod rather than in with the gearknob and handbrake.

[pil2255]

I will have a look at the belt arrangement and gear configuration and update !!
I know the door opener is in its own pod on the tunnel.
