I have a 87 B150 van with a 225.

I'm in the process of making 10 years of repairs that I had never had the time or money for prior. In so doing, I am eliminating all the options I don't need, don't want, and/or are more trouble than they are worth.

At some point I will be eliminating the ESA and reverting to partial '70s spark/engine control technology.

In the meantime I am generally cleaning up the engine, getting the ignition/emissions stuff to 98% for inspection, I replaced the manifold gaskets and had the manifolds machined, I'm replacing the entire exhaust, smog tubes and smog pump, replacing all the vacuum, heater and fuel hoses (I replaced the water pump just to replace that little hose you can't get with the pump attached), restoring the engine wiring harnass, painting some of the rustier engine accesories, etc.

I have eliminated the air conditioning and cruise control.

Today I went to Pep Boys for a bunch of 'tune-up' parts for putting it back together including a non-AC belt for the smog pump. When I got home I realized that not only does the belt they gave me not fit, but it seems that no belt would work with the pulleys and brackets I have. The neck of the water pump is in the way of the belt, and the belt is too long. (The A/C pully had kept the original belt away from the neck, and behind the pulley, of the water pump)

It seems if there was a groove in the water pump pulley for the smog pump, that the belt provided would work just fine.

Is there a 2-groove water pump pulley for /6s with smog pumps but not A/C? Does anyone have any pictures of a 225 with such a configuration? Is there a different smog pump bracket for non-A/C?

Any input would be greatly appreciated.

I've since noticed that the alternator has a second groove that aligns the smog pulley. I ran a belt around the harmonic balancer, alternator and smog pump and found that it almost works (not enough clearance at the front of the head, but shimming the smog pump bracket, alternator and altenator bracket should provide adequate clearance.)

The only problem with this is that any belt anyone lists for my van, my year, my motor w/smog pump and w/out A/C is +/-50", which is way too short to go around those 3 pulleys.

Ed,both my slant vans had smog pumps but no air cond so I'm not sure I can be of much help.Mine are,belt around crank,waterpump,alt.Short belt around crank and pwr steering pump.Short belt around crank and smog pump.Cann't find my FSM so not sure how the air cond changed up the mix of pulleys and belts.I'm thinking you should maybe have 3 pulley set on crank? One on the waterpump? Two groves on the alt isn't a problem just use one that lines up with water/crank.I've got a double grove alt on one of my rigs it just came off a newer v8/air van so just an extra grove.Anyway not much help,maybe Agressive Ted will chime in as he's got a van or two in the family.Good Luck

Duh,just thought about what I posted and I mean Reed not Ted although I'm sure he may have mentioned a van.And on mine front crank pulley is pwr steering,middle grove is water pump/alt,and back pulley was for the smog.In GoodYear belts 15402 is pwr steering and 15561 is alt/waterpump,don't know on smog.I need a beer,I cann't think straight

I need to take another look at running a belt around the crank and smog pump. Maybe in a certain position the belt clears the water pump neck.

I also need to check if what Pep Boys gave me was a 50" belt. If math is to be beleived, a 50" belt would make about a 15" circle. I think the belt they gave me was longer than that.

I too have a 3-groove crank, and the smog is the rear-most one. I kind of need to get this right before I can install the other belts.

Thanks for your help. If you happen to find the # of the smog belt, that would be a great help.

I double checked. There is no way a belt could go around only the crank and smog pump without hitting the the water pump neck.

You are missing the idler pulley used on engines not equipped with an A/C compressor. Here are the relevant pages from the '87 parts manual; I've enlarged the non-A/C idler setup in the pulleys view so you can see exactly how it's supposed to go together (as always, click the image for a larger version):

So,I'm wondering if maybe a little earlier /6 smog bracket might work on Eds van? Both mine set down fairly low with no clearance problems,just wondering,what say you Dan? Living in the northwest we don't worry to much about aircond mostly rely on the 50/50 or 60/40 type air

Thanks for the info. I wish I saw this before I left the house this morning.

I actually walked out of the local Dodge dealer with less informed versions of both of those pages and a hand-written list of the part#s they could get me, which might be everything I need but the spacer.

The blow up of the idler they gave me lacked the key that your page has.

I took a walk around the closest junkyard. I saw not one slant six (or no Dodges old enough to have had one, really) and only one Dodge with a v-belt idler pulley (a double groove one in a 3.9 V6 Dakota). I couldn't find a part # on it.

I went home, poked around the internet and found that I could use washers as spacers.

I ordered the balance of the parts from chryslerdirect.com (My Dodge dealer's parts dept. cant be bothered with truck parts, or old vehicles. They really want nothing to do with my van, or the $60 I might spend there.)

They processed my payment and everything only to send me an email hours later that they couldn't actually fill the order.

I think I'll cancel the order in the morning. I may let the local dealer see what he can get (at least they won't charge me until all the parts are in, so if they can't get them all, I'll know it ahead of time).

Might anyone on this board have hung onto these parts after adding A/C to a formerly non-A/C motor that they'd care to sell me?

Similarly, might anyone be interested in my A/C parts? (anyone with a use for them may have them for the cost of shipping).

Ed,I still think you could just move the smog pump down to the lower location where it mounted on earlier /6 without air.The vans didn't change much over the years and neither did the /6 so if it was mine thats what I'd be trying.I've got a bracket and pump around here someplace,let me do some more mind drawings and work it out in the ole gray matter.It could be that the pump itself changed enough to not fit an earlier bracket plus yours may pump air into the head as well as exh pipe so replumbing might be in order.Think I've still got a pump and bracket from a 90 318 van so if I can find all this stuff I'll get back to you on matching up parts an pieces.I'll dig around tomorrow and get back to you,hang on I don't move as fast as I used to

The pump is pretty small and the bracket is needlessly bigger than the pump, so I'm guessing a newer pump design is not what had precipitated the move.

May have just been a matter of A/C becoming more common, so they made a bracket to accomodate both.

Do you have any photos of the smog pump end of your van motor? (Don't go to the trouble of taking one if you don't.) I'd just be curious to see where they put it, what they had bolted it to, etc.

This is all acedemic anyway since I called the online parts place, and found the only part they couldn't get was the bolt. I told them to cancel the nut as well, just give me the pully and the shields, and I'll get the bolt, nut and spacer(s) form McMaster Carr.

Thanks again for all your help.

The air pumps themselves are very widely interchangeable. For reference, here's the earlier setup:

that totally would've worked. Oh well.

Thanks for the help. (next time I'll let this board do it's thing before I go buying stuff.)

..Actually, it wouldn't work. I don't have the 2-groove water pump pulley, but that pully would've solved the problem by itself.

Ed,mine are all single grove waterpump pulleys also.The blowup Dan posted for earlier car pumps shows it sitting higher than the vans.It's like down above the pwrsteering more with a back set so it lines up with the crank inner pulley.I don't know,the smog belt isn't much different in length than the pwr steering belt.Are you taking the air cond off for weight savings or just because it's toast?You could always just leave it on as an idler with all the belts like they are unless it's froze up.
