7.3 Water Pump leak?

I am hoping this is just expansion tank overflow maybe?

2004 Brazillian built RH drive model with the 2003 7.3 engine.

At 85000 miles original, I decided to drain and replace the green radiator fluid, because it was losing its color and looking rather tired.

No problem and topped it off with new green stuff.

Recently had occasion to be underneath the vehicle and noticed drops of green rad fluid on the front sway bar after a short 10 mile drive, only a few say 3 - no pool of green fluid on the ground at all.

I have noticed that since replacing the fluid - the expansion tank seems to always bee at min level after a long drive - say 300 miles.

I top it off to max and next long drove its back to min

It isn't a lot of fluid - just a bit!

When underneath I tried to ascertain where the green fluids coming from.

Above the sway bar I could see behind the harmonic balancer on the end of the crank is a series if bolts that presumably hold in the front crank shaft oil seal.

There was a green drop of rad fluid on just one of these bolt heads.

No sign of it actually leaking from there it just appears to drip from there.

So i figure likely it's coming from the water pump above - but I couldn't see any leak from underneath from the water pump.

There's no oil in the radiator fluid and likewise no rad fluid in the engine oil.

Engine temps are normal & car runs fine.

So I am then wondering - is there a radiator expansion tank overflow, for excess fluid to be expelled when it expands with heat after each time I top it off cold before a trip?

Could it be just normal overflow a few drops I am seeing or am I looking at a new water pump some time soon?

Anyone know how frequently the water pump seal is likely to go on these?

It gets driven relatively little miles - had it since christmas 2006 (i.e 5 years) and only added 21000 miles in that time. Usually only use it to tow my boat - it sits for long periods (weeks at a time).

I'm scared to go anywhere long distance if the water pumps about to quit on me.

I don't recall ever seeing any green radiator fluid drips underneath before I recently exchanged the rad fluid for new green stuff.

I don't think the radiator drain tap is directly above where I am seeing the drips... it could be weeping maybe I should check that (my son did it up and being plastic I told him not to overdo it).

So is there some overflow drain pipe from the radiator expansion tank that I'm not seeing which is dripping down past the harmonic balancer onto the front sway bar?

Green fluid drips underneath is not normal - right?

Many thanks in advance.

Green drips are not normal. Sounds like either a water pump or a thermostat housing leaking.

Thanks

Thanks DD - Can anyone point me to where to look for the thermostat housing?

I take it there is no overflow pipe from the expansion tank then?

Again many thanks in advance.

Thermostat housing is part of the water pump.

The thermostat housing is where the upper hose attaches to the top of the water pump.

Thanks guys

Thanks a lot gentlemen!

I shall get in there while the engines cold with a mirror on a stick and see what i can find!

It seems that green fuids a bad sign then and something i need to fix before it gets worse and costs a small fortune.

As another question - whats a water pump and new thermostat likely to cost state4side roughly?

I'll get a quote locally from my ford dealer....but I know from experience they will gouge me.

A F250 that would sell second hand for say$20K stateside will sell for 80,000 here and our dollar is at parity with yours.

Ford stopped importing the f 250s a few years back now and they are in short supply locally and command huge prices in the RH drive format that came out of the Brazil plant.

For that reason the quote for a new water pump and thermostat fitted by my local ford dealer will likely be $5k - $10K.

This will end up being a job where I import the parts and do the work myself probably.

Its a coonazzed crazy damn world we live in let me tell you!

Cheers!

If I remember right I think I can pick up an aftermarket water pump and oem thermostat for between $200 and $300 I'd have to check to be exact.
