Water Pump Issues...

I have a 1987 302 and I do not have the serpentine set up for it. But I do have all the V-belt pulleys. And from what I understand I can't use my pulleys on this water pump because it is reverse flow. What can I do to make my v-belt pulleys work? The easiest and cheapest way?

Are you building a motor or a koi pond? ;) Your water pump link is off.....

You need to change to a standard rotation pump and also get the correct timing chain cover....they are different.

You have to change your timing cover. Look at the water passages. Also notice the complete lack of a fuel pump mounting boss on the 5.0 cover on the right.

You can make an early pump fit a late timing cover and it will be OK around town. On a long freeway cruise it will run so hot the paint will burn off the engine. Seen it.
You can buy the correct early style timing cover new for less than $100. You might be able to scrounge up a good used one. If you plan on running a mechanical fuel pump you'll also need the fuel pump eccentric for the end of the cam. If you go electric pump then you'll need a block off plate for the cover.

Red66GTcoupe: Lol its a motor haha. I didn't mean for it to even be a link.

GypsyR: The farthest I plan on driving the car is to Charlotte, NC and its about 3hrs highway from my house... Would the electric water pump be a better idea. Or is there something else I can do? Besides serpentine.

GypsyR, sorry I miss read your thread. You said if i put a late water pump on a timing cover it will over heat.. That is understanable. But, if i use both a early water pump and early timing cover will it still have heating problems? Plus i will be using a 3 row aluminum radiator. And I'll probably be using a Holley Red electric fuel pump anyway. Blocking the timing cover isn't a problem.

That v-belt conversion pump might create other problems for him.....the lower radiator hose outlet is on the wrong side....

The easiest and cheapest way for him will be to buy the standard rotation stock pump and the 289 timing chain cover.

Cody many people use a 302 style radiator because cross flow is supposed to cool better and such, rumor has it that Ford went that route for a reason. so you should be able to go that route with the conversion pump, but dont forget to double check your pulley alignment and clearances.

Do you need a new radiator? If not look at your costs involved before you commit down a path, it gets expensive fast, even if you get that radiator and keep your timing cover you will need to deal with the dipstick to go in the timing cover because you cant use the pan that the 5.0 uses, so that means drilling into that cover. You will also need to use an electric fuel pump, no biggie if you are going EFI, but for a carb its overkill.


If you can find a 289 timing cover with a pointer on the drivers side you can use a 289 water pump and keep your current radiator, look period correct and save money.

If the pulleys are off of your 68 you will also have an issue with alignment..The pulley mounting surface on a 5.0 balancer sticks out further than a 68 balancer..Also the 68 pulley will have 3 bolt holes where the 5.0 has 4...You can buy aftermarket balancers that will fix these issues for you..

Jeez, I'M starting to get confused.
OK cody, look at the ports on the picture I put up. The ports accomodate "standard" (vintage) water pumps on the left where the right side cover is for "reverse" rotation or serpentine water pumps. You need to match the pump to the timing cover as the different pumps have matching ports on their backsides. If you have a complete '68 289 or 302 engine, simply grab the timing cover, water pump and all of it and transplant. You just mentioned having pulleys.
Fstbk, as far as I can tell that water pump you linked to is a late style pump that is made to work on a standard rotation, or old style, timing cover. They list the FRP part # for that timing cover. It won't help adapt an early water pump to a late timing cover. I lke it though, I can see myself buying one to get rid at least one hefty old cast iron pump I have in use. Thanks for the link.
Frdnut makes some good points. I too have run into some very annoying pulley alignment issues which required a new balancer to finally sort out. (After trying any number of pulleys and brackets out of my stash and about pulling my hair out.)

GypsyR: I was getting confused too haha. But I do have the original pulleys. And the engine Im putting in the car is a 1987. I do not have the old engine. So, if I buy a early model timing cover and match a water pump to it, will I be fine???
Sorry for the confusion everybody and thank you very much for the help

Cody: using that balancer, did you notice all of the pulley spacers that are available for it? You will have a fun time trying to get all of the pulleys to line up. Water pump, alternator, and crank. Also notice that all of those spacers shown are 4-bolt which means they are for the 5.0 pulleys and not the vintage 3 bolt pulleys. So, with that balancer, if your stock vintage pulley will bolt to it without a spacer, you might be in luck, but you still might need spacers on your water pump pulley and alternator.

There are no 3 bolt spacers because the balancer is designed to the early 289/302 depth so no spacers are necessary if you are using those early 3 bolt pulleys...If you want to use pulleys for later 302/351s or a 5.0 serpentine system you need the spacers to get the required depth....
The problem when using V belt pulleys on a 5.0 motor is that the balancer sticks out further than the older 302s..This means that no matter what early timing cover,water pump and pulleys you use it will never line up with the crank pulley using the stock 5.0 balancer..
Here is a pic of a 5.0 with V pulleys on it..You can see the crank pulley is too far forward with the stock 5.0 balancer.

Red66 is giving good advice too.
Yes. It doesn't have to be "vintage" just a V-belt standard rotation timing cover. Ford used them well into the 1980's. Some of the later ones had the fuel pump boss blocked off or missing entirely. Come to think of it, I think a have one of those somewhere. They were still correct for the rotation though.
Just to confuse things even more, around 1984 the Crown Victorias and Grand Marquis cars used serpentine belts but ran the water pump in standard rotation. THis made their water pump pulleys unique as they were grooved for the inside of the belt to run on versus all the reverse rotation setups where the pulley is flat as it runs off the "back" of the belt. I've seen one of these setups retrofitted to an old F100 pickup and it was a super clean and slick setup. I took some fairly crummy pictures at the time but don't know what all parts he used. I'd love to score that complete setup off a junkyard car. Trying to mix and match is best done with v-belts though, they can tolerate a little misalignment better.

Installing a 5.0 in a early car is a snap. All you need is the stone-stock 65-69 pulleys, brackets, and timing cover. To make this work on your 5.0 get the 5.0 conversion balancer, which is configured the same as the 65-69 balancer, but is balanced for the 5.0. Everything bolts on, and when done looks like stone-stock 65-69, so if stealth is in your plan, no one will know it's an HO engine. Any stock 65-69 stuff you need is available new, too.

I've noticed everyone say to change the timing cover but you shouldn't need to. The 5.0 guys swap to standard rotation pumps and to get the ports to line up they just swap out the back cover of the pump with the cover from the original reverse rotation pump. One of the pumps was from an 83 Thunderbird with a 5.0. I can't help with the pulley issue as they keep the serpentine pulleys, which is what I am doing (only running alt and water pump)

There's no doubt that both pumps will bolt to both covers, however since the covers have the inlet/outlets angled differently, it can create turbulence there and affect the flow of coolant. When I put my new 331 into my 5.0, I had bought a chromed timing cover on ebay that was for a standard rotation pump. I was running a reverse rotation pump. Not knowing the cover wasnt correct, I put it on. And my brand new motor was running hot! Took me weeks to figure that one out. I'm not saying this will happen everytime, but with the combination I had, it didnt work out. I changed it to a reverse rotation cover and my heating issue was solved.
