Leaking water pump

So I noticed a wet spot under the truck, and my 1st thought was "Darn, my fuel filter change caused a leak somehow".
Turns out, it is the water pump leaking coolant.
I looked in the degas, and it is bone dry.

If memory serves me, that tank should have a bunch of coolant in it, right?

I've done waterpumps on cars, so other than the size difference, it should be the same right?

Maybe change over to gold coolant while I'm messing around with coolant anyways?

It really stinks that I just had the coolant flushed and replaced a few months back.

The main difference is the water pump has the thermostat housing and lower radiator hose attached - it is bigger. You also need to rent a tool to get the fan off - remember it has reverse threads - spins off to the right.

I know this will start another coolant war, but here goes - you still have to test the gold coolant regularly and add SCA - International has switched to the extended life coolants - they have life expectancies in the 300,000-750,000 mile range. I personally use Shell Rotella ELC. Fill it and forget it.

I just did the pump on my buddies 02,the threads are standard.The tool I got at autozone,it came in a set,but the one i needed to hold the pulley was about 2 1/8".Ive heard about some fans that are reverse thread,they are labeled on the shroud.Good luck Al

If you use a rental tool, check the dimensions first. IIRC, the fan nut is 1 7/8 and the one I rented from AutoZone was stretched out to 2 1/8 and slipped off of the nut.

That's really strange. My 03 has right handed threads, and the fan clutch is the same part number from 99-03 (Motorcraft F81Z8A616DA)

Mine is also standard threads, when you get the old pump off clean the mating surface real well. The new pump will come with a new O ring, when I did mine i put a small amount of silicone over the O ring when re installing. Also I did the new thermostat and housing, belt, idler pulley, along with new hoses and belt. Just so that I didn't have to go back in after doing the flush and fill with Rotella ELC. Just a tip is to get the upper hose for a dual alternator set up, it goes behind the belt instead of thru it, so if you have a belt problem or other issue youdon't have to pull the hose to work on it. Not wasting the expensive new coolant.

If you loosen the 4 bolts that hold the pulley on just a little,it will give the wrench more to bite.Once I had the wrench holding the pulley from turning in place I used a long pipewrench,1 smack with a hammer and it was loose.

OK - this brings up a greater question. I just checked RockAuto, Autozone, Advance Auto, and NAPA - they all only have one fan clutch assembly from the 99-03 7.3's and it has right handed threads - if some of you have left handed threads - where would you get a fan clutch for them? I haven't called Ford yet, but you would think that if it were somehow an option, that the major parts stores would stock both. Very, very weird.

The F81Z-8A616-DA has right hand threads. Right hand thread IS standard thread. remove fan clutch counter-clockwise. There is No fan clutch that is left hand thread ( clockwise to loosen) in our 99-03 7.3 trucks.If a waterpump pulley has ribs in it or deep V for old style V belt drive it would have reverse threads, But if it is smooth like ours its driven by the back side of the belt so it has to have standard ( right hand ) threads or it would have a chance of spinning off whille engine is running. Our waterpumps ARE reverse rotation so the threads are always tightening.

I've already got dual alternators, so that should save me some loot on the new hose.
I didn't realize that some folks had to pull the hose to change the belt. That stinks.

With picture! Maybe not the pump?

So I ran a dye pack through the coolant system, and so far the only spot I can see a leak is at this junction of the lower radiator hose and the water pump.
There is a gasket there, I wonder if it can be replaced?
I tried to tighten the bolts holding it together, but they didn't seem to move at all.


This next pic is upside down, so the drip looks like it's on top.



So does anybody know if I can swap the gasket, or do I need to buy the whole pump?

Thanks.

Mine was leaking from there as well - I got the o-ring from RockAuto - when I took the old one off, I noticed the ridge where the gasket seated had a groove eroded in it. I cleaned it up, built the ridge up with silly putty (JB Weld) and put it back together with a new o-ring. Worked like a charm. No leaks for over 10,000 miles.

Oh, and I love your kid's drawing - by the time he's six he'll be a real artist.

Now that's funny right there.
