Yoohoo belt?
 
Well I'm at the end of rebuilding my NA RX7 and have a few last moment buys I need to make.

One of them being a Yoohoo belt, problem is I cant find a place with Yoohoo belts in stock.

That was the first place I checked and they are out of stock.

I hate that there is no edit button/that its hard to find

Anyways I think what I might end up doing is just gutting the air pump or just fabbing up my own tension pulley

If you do go the gutting route...I'd like to know how it goes, and what you did. I am incredibly happy with my yoohoo, but also curious about gutting the air pump...

Why gut the air pump?(have you seen the inside if one?..its like WTF!?)Drop the air pump.
Run a dual belt pulley on the alternator so the waterpump doesn't slip.2 belts,same size.
It is cheaper than a Yoohoo setup and just as effective.

It's a power steering belt for a chrysler new yorker. Like a 99model. 2 out of 3 places within 5min from my house whrn I needed one. Just google search yoo hoo and new yorker and you will find the part number

@Sevens4me
I'll take some pictures soon once I button everything up. I just fired her up for the first time in 4 months and I'm too full of excitement to get to drive her again.

@Mistersty69
Why not gut it?

It's not that confusing to gut, I wouldn't have to buy/wait for a pulley or another belt and it's easier/cheaper than fabricating your own. Plus it saves me space since I dont have to worry about getting rid of it (without the garbage man whining)

@wankelbug
Thanks I'll keep that in mind

Okay, well the hardest part was getting the back cover off, after unbolting everything I had to take a junk flathead screwdriver and use it as a wedge to pry on it until it let go of two pins.

You have 3 ceramic plates that have bearings attached to them, and are on a fixed shaft. As the airpump rotates there is a drum inside which is responsible for compression of the air and rotation of the ceramic plates (its movement is like that of a rotary engine) The only thing you have to do is remove the ceramic plates and any of its seals. IMO this thing is a simplified rotary powered by an outside source.

Here is a picture of what I had taken out. The seals that butted up against the flat portion of the ceramic plates basically crumbled the moment I removed the plates, so those aren't in the picture and I had yet to put the end ring/bearing back on

It is basically none of the above. Couldn't find it googling yoo hoo new yorker and it isn't a power steering belt, and it isn't a 99 model. Thanks for the bad info.

This is what it is: Cam to Water Pump Belt for a 1986 Dodge Caravan with the 2.6L engine. Must be a 2.6L The belt configuration for the 2.2L was TOTALLY different.

Belt dimensions: 3/8" x 22.125"
Gates P/N: 7215

I stopped eating alternator belts when I stopped using the mini-belt on the water pump.

With the mini-belt and an alternator belt, BOTH belts would wear at a phenomenal rate. Noticeable slop in the belts after 100 miles, and useless/out of adjustment after 1000mi. (One 1000mi alternator belt was so slack that it was able to slice one of the vacuum hoses to the distributor!)

I have 2000mi on an alternator belt, sans minibelt, and it doesn't even need adjusted yet.

I stopped using yoohoo belts years ago and stopped recommending them soon after.

The yahoo belt is a 4L22. It had a (deserved) reputation for eating water pump bearings because it had lots of belt tension. I tried a 4L23 which is one inch longer and it works great for getting rid of pulley squeal and has little tension so no adverse effects. It looks loose as hell when installed but I used it on my 12 A and a friends 13B and it worked for both. I've never seen anyone else try this but I'm 2 for 2 so far. A double belt alt pulley will work too but it's much more money.

Guys I have a question about my yoohoo. 89 S5 front cover. I just installed mine, just a 3L220 from the lawnmower/small engines place in towne. I didn't have to remove the alt belt obviously, and have never had a problem with my AC and PS belts getting them retensioned after snapping WP belts. After installation of the 3L220, it fits real snug to where I don't have much slack at all and turning just the belt turns all the belts and pulleys. I had no problem bumping it on with the starter with help from my awesome little brother. But once I start the car to run it, I get a little chirp from the Alt/WP belt. We tightened it a little, as it had a good bit of slack, and it got significantly worse. After only a few seconds the alt pulley, not the alt itself, was so hot it was untouchable, and the belt began to smoke, so I woofed her and shut it off. It shuts off much faster now since I have the extra belt, so I'm not sure if I should rev it much higher before I turn it off to prevent a flood.
My point is, since I have a yoohoo belt installed, should I run more slack on my alt/WP belt because I don't have to accommodate as much for the WP pulley? I'm worried I won't make it up my very short street to the stop sign before I snap my alt belt and won't make it the 35 miles to Tallahassee for another. Also, is it possible that the snugness of the 3L220 is side-loading my WP?
