Default Water Pump 'weep hole' on P/N 23522707

Ron, AAron, Thomas and all; the water pump on our newly acquired 1999 LXi with Series 60 12.7 L engine, shows signs of leaking coolant through the 'weep hole' in the pump housing. I was able to find the 'weep hole' yesterday after carefully cleaning and drying the bottom of the pump. Initially the leak appeared to originate from the lower bypass hose to the coolant filter but now I'm pretty confidant the water pump seal is passing coolant overboard through the 'weep hole'.

Here is a link for the picture of the 'weep hole' for water pump P/N 23522707.

We both decided I need to bite the bullet and get it changed along with the coolant filter hoses. What the heck, I'll just pull it out of the fuel money account. Probably won't even notice it with the price of fuel. ...NOT!

Will update you next week.

Dick,on almost every s60 engine i have ever seen there was a coolant leak,the leak is normally a cold water leak,and its on the drivers side.
the leak is from a hose way up on top of the head normally snugging up the clamp stops the leak.

That's exactly what happened to me a week ago Randy. Looked like it was coming out of the pump, but found it was weeping from the hose above. Really hard to see, but was able to feel enough from underneath to get a socket on the hose clamp.

Rick and Randy; I have good news...yesterday I snugged up every hose clamp above the S-60 water pump and after observing 24 hours later, the coolant leak has disappeared. The entire area that had previously been seeping coolant is now bone dry.

Thanks to the power of WOG, I saved some cash and most importantly, I received a 'spot-on' correct diagnosis.

Thanks Randy and Rick D.

Randy, I confirmed my top hose did weep last year and tightening the clamp was the fix. Would like to refit that small hose. Is it possible to R&R it without removing the pump?

If you’re going to own and drive a Wanderlodge, you need to spend $50 or so and buy a Stant radiator pressure tester off eBay. Nothing can compare. Take off the cap, put the tester on, pump it up, fix the leaks if any. When it holds pressure, your finished. Head on down the road. I check mine before every trip. Takes 10 minutes. Just a suggestion.

Clemb,i have a couple of the Stant pressure testers,and a few adapters to fit most anything,or so i thought.
My Son-in-law was here and hes a mechanic and he was saying he needed to buy one,so i offered to give him one with adapters.
He was so excited! until he saw the adapters (mine are all for big stuff,not hondas and stuff).
Then he was telling me theres a million adapters anymore,that the rad necks are not standard these days.
So i checked the tools out on ebay,sure enough its a special world out there now...

Thanks, however I was never a fan of pumping air in a below temp cooling system and block. I guess if you are careful and dont take pressure over 8 to 9 psi it is ok.On r&r I tend to only tighten bands to snug then bring them up to snug-plus after and during a heat cycle. Like electrical fuses, often leaks are a sign of other issues like, hose material age, motormounts and casting rust. A year ago when a cold temp night proved a leak at this top hose, I never felt comfortable that the band going lose was the issue and that my simple tighten was the best repair.
Theory:This short hose has little length between bands to absorb temp change distortion and now the hose age issues prove a need to r&r.when colder than 35 deg, the hose pulls at both bands ?
For now the best repair is never put my bus in a climate below 45 deg but it is for sale and the N.O. may live north.
