5.0 water pump, alternator, belts and running hot

[afreejack]

I have a 66 convertible with a 5.0 taken from an 82. After doing various other things to correct the sloppy work the previous owner did, it's now a driver. Since I have been driving it around, I noticed that it's running pretty hot. I dont know how many degrees, but the temp gage is over at the 2nd line from the right most of the time.

This is what I have:
The crank has a V pulley and two serpentine pulleys. It uses a serpentine belt driven by the serpentine pulley closest to the engine.
The water pump has the inlet on the passenger side and the pulley on it seems pretty smooth rather than have the ridges like the crank and alernator pulley.

The alternator upper bracket was someone's handmade piece of shi...er...steel that they bolted to the block and had a nut welded the bracket for bolting the alternator to it. As a result the back of alternator was against the block and it was jammed in there with a belt that was too small for it. And you could only move the alternator about 1/4 inch to put the belt on.
I bought an alternator bracket. Due to the fact that I was using the serpentine pulley on the engine to drive it, I had to put shims in the bracket (between the bracket and water pump, and between the alternator and head) to align the pulleys. I have plenty of room to move the alternator and got a new serpentine belt that was the right size.

Now, when I start the car, I get an extremely loud squeal for a few minutes and when I goose the accelerator, it chirps.

Would the cause of the squeal be the water pump pulley? does it need to be replaced since it looks so smooth? is it the correct pulley for that pump? Would this also be a cause of the car running hot?

Is the water pump correct for the engine? Should I get a water pump with the inlet on the drivers side instead? (I know I would have to change the radiator too) Is this what is known as a reverse flow water pump? (the inlet also covers the timing marks) How can I tell the difference?

How hard is it to replace all the pulleys with V-style? Since this is an 82 engine would the 66 289 pulleys bolt to it, or would I have to look for something else?

Oh, God. You're the poster boy now for "why you should never mix Ford FEAD components" . That said, you've got multiple problems here, all stemming from mismatched parts. Based on what you descibed, you've got a pre 70 water pump that's now being spun backwards. That's only part of the problem. If you're still running the 66 style radiator, that's another factor in the overheating. The coolant enters and exits from the same side of the radiator, the driver's side cooling tubes get neglected from the flow pattern as water always takes the shortest route to the exit. A third problem is your depending on a 40+ year old gauge that wasn't always correct to start with when new. And asssuming that where the needle pointing is the correct temperature indication. Easiest way to correct this is to choose a FEAD(Front End Accessory Drive) from a 1970-up 302 and use all the parts together, and install a better radiator with a driver's side outlet. And install a mechanical temperature gauge so that you can accurately see what temperature the coolant actually is.

Thanks for the quick reply.

Luckily (or unluckily), I can't take the credit for all the mixing and matching that was done on the car. That honor goes to the guy who had it before me. This job is just another in a long line of corrections I've had to make to it.

AS for the gage, I know to take what it reads with a grain of salt, but one thing I did figure out is that when the thermostat opens (180) the gage is a little bit to the left of center.

So what I'm looking at here is that I need to replace the water pump and radiator, and find a pulley set for a 1970 or newer 302. Also, alternator brackets and maybe an alternator?

Depending on the casting numbers on the timing cover you may need to replace that too. The early 60 covers don't function with the later 60's to mid 80's (std rotation) waterpumps. Ford used a reverse rotation pump on the 79-85 Mustangs that mated with the std rotation timing covers (but apparently didn't cool too well as they made a complete revision to both the cover and the pump in 86) The Vics, Towncars and Marquis used a std rotation pump (and timing cover)all the way up to the end of the small block in 91. I know all this gets confusing, that's why I recommend using parts from the same application if in doubt. I've somewhat gotten a hands on education in the various application's parts in playing with this stuff over the years. Some application parts can be mixed, if you know what to use The 70's timing covers used a bolt on timing pointer too. I've got a pic of some of this stuff on my photobucket pages http://s125.photobucket.com/albums/p53/baddad457/ The pointer I have pics of in there is painted Ford Blue. I think there's also a pic of a reverse timing cover, next to a std rotation cover. Ford made at least a half dozen (or more) different small block timing covers over the 40+ years of production.

looking at the pics of the timing covers: Which one was the std and which is the reverse?

One other thing I noticed was the fan blades on the alternator. The engine turns clockwise and the way the alternator fan turns it seems it would do a better job of cooling the alternator turning counter clockwise. Or does it make a difference?

The one with the arrow pointing to the dipstick tube boss is the std rotation cover. If I'm not mistaken that particular cover is a 69 casting (casting numbers are in another pic there) There are about a half dozen variations of this cover, but the same basic cover was used from the late 60's to the mid 80's. The other cover came from a late 80's pickup truck, but is the same cover used on the 86-93 Stangs. There's another reverse cover used with the 88-93 T-Bird/Cougar, 94-95 Stang and the 96-01 Explorer/Mountaineer 5.0 that uses a completely different water pump ( 2 actually, a separate pump was used for the Explorer/Mountaineer 5.0's)
