Serpentine belt/pulley swap.

[Anonymous]

Heya, I was looking at the brackets and accesories on my engine this weekend, and I noticed they're very similar to ones used on SB Ford V8s. This leads me to wonder whether or not its possible to convert from v-belts to serpentine.

There's the question of how to setup the system so the water pump turns the right way, but I think this is doable.

Any thoughts? Has someone already beaten me to this?

Doesn't the water pump run in the opposite direction on a serpentine belt driven engine?

Usually, yes. I can't help but think that there's another way to achieve this goal.

Ideas....why not see if it's possible to modify an existing water pump to reverse flow? The primary modification would have to be to the impeller, but I've done something like it before.

Creative use of tensioner/idler pulleys, and relocation of at least one accessory are another option.

I wish I actually had my engine here in front of me so I could figure it out!

the 2.3 lima used a serptine standard direction pump. some rangers had simple a vbelt setup only with serp belts ( no spring tensionor) this is something I am looking into. maybe a couple welded or cast brackets and an off the shelf new car tensioner.

Good call on the 2.3. I'm thinking that for the most part this can be done with Ford parts I find at the wreckers.

That's what I did this past weekend. I converted a manual steering 1964 Ford F100 to power steering using: crank pulley and P/S pump bracket from a 1970 Galaxie, P/S pump/high pressure hose from 1979 F150, steering gear/column from 1974 F100, and a V belt I dug out of the big box o' belts in the garage.

It took a little work, but it all came together, with the single biggest problem being the engine mount on the driver's side. That was nothing that a little cutting and welding didn't fix.

The 2.3 and 2.5 HSC I4's run offset water pumps and a super thin belt drive. They are not serpentine, but one of the trimest in the business. Plenty of Fords have the cut down Falcon I6. The 250 six could take the 2.5 Taurus gear as a straight bolt in since the deck heights are similar.

Is there an advantage to having a Serpentine belt and pulleys?

I don't think I've seen a Taurus with a 4 banger since sometime in the late 1980s. That same engine was used in other cars though, like the Tempo.

PLP6400: Serpentine drive is more efficient, as well as cooler looking.

the EFI lima motors have a serp setup on them....one with a tensioner at least. the carbed ranger 2.0L had a serp setup that worked similar to a v-belt setup.

also they are just not more effecent but also able to transmit more power for the same tension/pulley size

I am not sure if a bolt on WP pulley will exist but maybe graft the ring from one onto a 200 pulley? if you are gonna run a custom rank pulley anyway offset can be played with to gain clearance of anything in the way

A crank pulley would probably have to be modified to fit. It would essentially be the same process as redrilling a flexplate or brake rotor.

I think there's a turbo 2.3 sitting in the corner of the garage, I'll have to dig it out and see how things work on it. (I had thought about using this engine, but it's a little high strung for street use. The cam's so lumpy it won't idle below 2000 rpm)

I say toss a stock cam in it and run that motor!!!

I was thinking one could turn down the outer ring a bit on the stock crank pulley then have a serp pulley that slips over it and bolts to the balancer. not sure if a setup using a tensionor could be done very easy but worth a shot. the big issue I see is having to make custom accesory brackets.

Naw, we're saving that engine for something special. We were going to toss it into a rusty old ranger pickup. Nobody could suspect a nasty old rattle trap of a truck would have over 400hp.

Talked to a friend last night who happens to be a master tech at Ford, and he thinks the water pumps are pretty close. We'll have to wait and see.

I'll keep you updated.

Correct on the 2.3, that's what I'm using for my 5.0 crank/wp/alt setup, but I am thinking it might have been only the non-ac ones that have it.

:idea: If anybody is going to a j/y check out 79-85 Ltd Crown Vics/Grand Marquis with a carb'd 302, they have a 4 pulley serpentine system with a standard rotation waterpump! I think it uses the alternator as a tensioner. I dont know how well it would adapt but its worth a shot.

a while back there was a thread about reversing the flow of coolant in a big six to help get rid of detonation (as it is, the coolant flows through the block, then the head, if it flows through the head first it cools it down more, thus helping to eliminate detonation)

someone (SR maybe?) brought up the fact that just reversing the way the pump spun wouldn't work because of the actual inlet and outlet ports of the water pump
it has to do with how they are formed, unless you change those ports then making the pump spin backwards would just cause worse cooling because it would just put a lot of turbulence in the coolant flow
