Belts question... ribbed?

Belts question... ribbed?
I got all the belts off my 88' today... lots of swear words found the air! At one point went and bought a set of open ended wrenches that "ratchet". I highly recommend not buying those from menardes. I still might try a craftsman set. These pieces of crap are going back. Anyway, I opened up the boxes I got for my belts and noticed they are all ribbed... the ones I took off only had one that was ribbed(I have no idea if the alternator belt was or not as it was MIA)... does this matter? Are they the correct belts? The ribbed fan belt is the same as the one I bought. Thanks

Nope.
Fit and enjoy.
Technology is a wonderful thing at times.
The "theory" is that the ribbed internal section allows the belt to flex around the smaller pulleys better?, runs quieter?, runs cooler????.
Had them downunder for a very long time, never had issues with them.

After seeing something weird a few years ago, I think the "teeth" (ribs) are actually there to cut costs. A few years ago I was helping a friend replace his waterpump. The waterpump wasn't part of the cambeltsetup but needed a toothed belt to work properly. Don't ask me what car it was but they fanbelt costed more than my belts... The crankpulley had teeth, the waterpump had teeth, the tensioner had none...

Are you talking about a toothed belt, such as are used for cam chain drives, or of the fan belts that have teeth-like indentations?

Yeah, that nomenclature thing.
1. Ancient tech. flat belts. My first car, a 23 T Ford was so equipped.
2. Old tech. smooth V belts.
3. Newer tech: As Grant describes. Tooth like indentations.
4. Newest tech: ribbed. Highs and lows along the long axis. Seen in Serpentine applications.
5. Other uses. Cogged. Precise teeth on the belt to match the drive and driven pulleys. In automobiles, cam timing.
6. My son found them in the drives of the CNC mills he has modernized for procucing his goods.
Yahoo, the last of six spark plugs in my daughter's soon to be gone Passat seated with my use of my DIY tool. Now, merely apply the last tug with a socket and my extra deep thin wall socket. One or mebbe two more hours and it is outta here!!!

944xjs,
I find it interesting that some of your belts were smooth and some ribbed. How many miles on your xjs? Do you think somebody already replaced some (or all) of the belts on your car previously?
I recently replaced all belts on my '86 and they were all ribbed (with teeth). The ones I removed seemed like been there from beginning of times.

Aye, that is classic serpentine. The path is "serpentine". Makes use of the inner surface and the outer to drive the "loads". Very impressive engineering.
My venerable Jeep and the LT1 SBC in my Jaguar are of the same vintage, 1994.
Each performs better than a classic multi belted "V" belt array.
And, tech advise is that, even if the Serpentine appears "battered" it will continue to serve. V's in similar circumstance are "done for".
Caveat: I did have trouble with the idler on the LT1, in relieving the tension, allowing
restringing after a PS pump replacement. The instructions in the factor manual seemed clear, but they did not work !! I overcame the tension and all has been well.
Great tech in my view.

I have used both and they are fine.
I don't know any open ended ratcheting wrenches to work. The angle in which you can tension any given adjuster is such that the ratchet fails to get to the next tooth. You have to do the pain staking flat by flat, wrench flipping, bs.
I'm almost to where I am going to cut most of the tensioners short so a deep well can be used at least on the end. I think the worst is the power steering but for some reason i especially despise the alternator.
Isn't the book time like 0.2 hours for all the belts?

When it rains it pours... I found the alternator belt. It's nicely wrapped around the crank pulley assembly on the inside. I can't even see which direction it's wrapped or anything. Just have half the belt hanging and I cannot get it out. I think I'm going to have to take the crank assembly off. Haha what a nightmare.

Its not that hard.
Mine had starter issues, oil filter housing leaking oil, sandwich plate weeping, engine OUT, did it all, belts, hoses, etc etc. Snowballed as they do, but very satifying.
The Efans made belt changing later on easy as any other car. Only 3 belts, and much more room.
RHD starter is near impossible to get out without lowering the suspension cradle, hahahaha.
