Wiggle in water pump

[IBSTROKIN]

Was helping my neighbor change his serp belt and just reached down and gave the fan a little wiggle back and forth and it moves ever so slightly side to side,up and down cross ways...........again,juts the slightest of movement but there is some movement there,doesnt leak or at least it wasnt leaking and he says he hasnt noticed any and danged if I could find any,should he worry about it? Oh its an 01,still onb factory fill,I think he said.SCAs checked ok on the test strips

There shouldnt be any movement. When I replaced MudHogs waterpump, it was a very firm feeling on the shaft. No movement, and actually took a little effort to turn as the pump seal grabs the shaft pretty hard.

SCA's are part of what destroys a waterpump, hence the reason International uses a filter head integrated into the pump. Ford (in the infinite wisdom) ditched the water pump filter, and now you get water pump failures from the sand and grit in the coolant.

SCA's turn into grit as they are picked away from the cylinder lining. Thats why they are "sacrificial coolant additives". They sacrifice instead of the actual cylinder wall!

FF is right there should be no lateral movement to the water pump shaft.

00-03 F650-750's used the filter boss pump but was the same as Navistars version the inlet neck is on the opposite side.

Replace ASAP! I've got my story and T-shirt. Mine had no symptoms around 100k, until the fam and I went on a camping trip. Sunday returning home there was a racquet so loud it was heard in the cab over everything else. 100 miles later I'm home. Still not a drop of coolant I have no idea what's wrong. Sounds like the tensioner is torpedoing (like the chubby 2.8 v-6 units) Turn engine off, get second opinion from nieghbor who promptly just grabs the fan with belt on and moves it 1/8" all over the place. With belt off it was closeer to 3/8" movement No damage to engine, didn't leak a drop, got me home in 100F weather on Sunday with 10k lbs TT, nagavator ( ) and kids... I wasn't complaining.

Me too!! Just make sure you torque the mounting bolts to 15 ft-lbs, NOT the value found on the other site's directions...

Gentlemen, I had a terrible waterpump failure on a 04. Shaft broke and let the fan climb thru the shroud and wack the hood . WE check waterpump shaft play once a week now.

Negihbor took his truck to dealer Friday to see about the pump,they told him it was the clutch fan and not the pump.Anybody hear of this?
