Does anyone know if EA-82's ever came set up with the surpintine bent setup, My dad is looking to change over, If they exist im looking for all the pully's nessasary, power steering pump,waterpump,alternator,and crank.

don't need the AC pully.

 

Tahnks in advance.

MPFI XT's were serpentine.

 

GD

Why? Is there that big an advantage to be worth finding all those new pulleys for everything?

No - it's a disadvantage really - extra tensioner bearings, more difficult to remove and intall, and the belt is more expensive. The two v belts are $11 for BOTH, and are easy to change. Plus if one dies, the other will carry you till you can replace it - if the serpentine goes......

my xt didn't have the serpentine belt, it had 3 belts. i think it was the xt6 that it.

+1.

 

Serp belts suck.

Let me revise that - later 80's MPFI XT's with the spider style intake have the serp belts.

 

XT6 also has them, but so does the XT4 later on in the series.

no you were right the first time... all XTs, weather its an early or late, 6, turbo or NA ALL should have serp belts. Serp belts dont suck, they are just different..... try spilling some coolant on a v and see what happend, serps grip better... if they sucked so much, why do all the new cars use serp belts? onn and on my 6 I have a replacement.. and its really easy to install, more so then a ea series motor belt.. ohh and it was $6.... and I have the same amount of tensioners as my ea cars in my 6... I have no biased either way tho... I have cars with both

I think the 85/86 MPFI (non turbo) was v-belt. At least I know the 85 GL-10 MPFI wagon I saw a while back was V....

 

Good to know the serp's are that cheap.... I still like the twin belts for redundancy, but hey - can't have it all I guess.

 

GD

I'm confused. I thought serp belt meant there was one belt driving the system

 

Okay, now I'm confused. I remember Phil keep saying he liked the XT's serp belt setup. Now I'm thinking he meant the multi ribbed belts.

 

Oh I'm confused. What are you guys talking about?

 

(Pardon me, I spent the last 4 hours in a data network closet tracing cables and finding where they go. I'm a bit fried)

you have the right idea - serpentine means it's a single belt - the "ribbed" style you refer to is basically synonomous.

 

GD

So, the XT has two serpentine belts then.

 

Since that's the case, serp belts rock compared to V-Belts. The two belts on the XT cost about the same as the two belts on the wagon. Plus, the tensioning is the exact same, because the belt setup is the exact same (apart from the pulleys having multiple ribs). Both the XT and Wagon have an inboard A/C pump and power steering. In fact, I'm pretty sure I buy the same diameter belts for the two.

 

One can conclude then, that converting to the serp belts style is simply a swap of pulleys and the A/C belt tensioner. However, it may not be this simple.

No - I think it's just a single belt..... otherwise you couldn't really call it a serpentine belt....

 

GD

I have a 86 MPFI XT Turbo in my possesion thats serpentine belted.

Never had any problems with the serp belts on my 6's, just the stupid crank pulley's:rolleyes:

heres how it is. Xts have 2 serp belts, and the setup is like the wagons and other thingies... one belt runs all, the other runs most. The XT6 only has one small belt... no PS so just water alt and AC... the wagons and the XTs are different, even 85-86... the wagon N/T MPFI will have V belts, the XT will have the SAME engine, just serp belts... Why? I donno. nothing else on the motor has changed.

XT Turbo with mulit ribbed belts:

XT6 you can see the fat 6 rib belt in thhe front, sorry only pic I have with a belt on the motor:confused:

wow thats turbo-gay! i have NEVER seen a car with more than one serpentine belt... it DOES sort of seem to remove the point, but really, thats the best of both worlds. no water slippage, better gripping, but you still have the redundancy.. i never understood why car mnaufacturers didnt just go like that anyhow, with the btter style belts in the same configuration they always used for the multi-v-belts...

 

leave it to subaru, huh??? they ACTUALLY did it the right way, but it was so un anticipated i actually called it "turbo-gay" (and i didnt mean to insult the concept of turbocharging, either abstract or concrete, in the slightest.)

wow thats turbo-gay!

Careful now... thats a pic of mike's car:eek:

wow thats turbo-gay!

Don't make me smack you!

Here is one of my 1985 EA82 N/A (obviously) XTs. 2 belts ran just like my other EA cars. They are just multi-groove belts/pulleys rather than standard V's. NOT serpentine (at no point are the flat sides ran over a smooth pulley like cars of today) . Components are interchangeable (by swapping pulleys). The advantage is less tendancy to slip.

 

 

 

I would consider the term "serpentine belt" to mean that it ran across many pulleys (5+?) and that its backside was run against some of these pulleys. Thus, serpentine would mean more of application than of belt design. Otherwise the belt design is multi-rib.

Yeah - that's how I use it as well. I have always used it to describe engines that have a single belt driving all accesories with usually a single tensioner.

 

I think you could say the XT6 is a serp system, and the XT just uses ribbed belts - which I must say I don't know why they would do this either.

 

GD

heh, the turbo-gay only applied to the odd application that we didnt expect... (those of us that weren't already aware..)

 

no automotive offense intended :- p

 

just being a little indulgent with my choice of werds.....

 

I'll say one last thing about serpentine... at least the defenition of it... its mostly used to describe a single multi ribbed belt that goes around all accessories and runs everything... Thing about it is that you can have one, just take the outer belt off, thats the harry line... I'm not sure that theres any other cars that have a 2 belt system where one of the belts runs everything anyway...

ohh and here:

http://en.wikipedia.org/wiki/Serpentine_belt

My old mans volvo definately fits into the serpentine category, all of the accesories are run from one LONG 3 ribbed belt. Its got one tensioner and runs through so many different pulleys you need a phd to install it.

 

Personally i think the ribbed belt designs are easier to change but they are definately easier to damage. I had an alternator belt snap on my car where a small stone had gotten jammed between the belt and the crank pulley, it just ripped a chunk outta the belt and made me an hour late for work as you have to drop an engine mount to change the belt on my wagon (stupid Hon-duh).

 

Its not worth the effort of swapping IMHO.

Definition: A type of flat rubber drive belt that is used to turn multiple accessories on the front of an engine. It is called a serpentine belt because of the way it snakes around the various pulleys. Many vehicles now have a single serpentine drive belt because it eliminates the need for several separate V-belts. A spring-loaded pulley maintains tension on the serpentine belt. This does away with the need to retension the belt when it is replaced. Serpentine belts generally last 25% to 50% longer than conventional V-belts.
