Cat Water Pump

Cold water leaks are common at clamp joints, and I have seen water pumps weep when cold but I always took that as the beginning of the end.

 

Run your hand up above the weep hole and feel for wet antifreeze . More than likely its a loose clamp on one of the upper hoses. When that happens it leaks down and drops off the weep hole and makes it look like a bad pump. Good Luck.

 

Take this for what it's worth. I put a reman pump on my 2ws, and for the first 100,000 miles it would do the same thing. Only when cold and only once in a while. Just a small puddle on shop floor come Monday morning. Came from weep hole. I just left it and it appears to fixed itself as it hasn't done it since in 6 months. My understanding is there is two ceramic seals that rub against each other and it just took that long to wear into each other to make a perfect seal. If its just a very small leak, I would keep an eye on it. Chances are it will seal up with some miles on it. Wierd stuff happens when it gets that cold, also if your running the red ELC coolant, it seems to leak more then the green for some reason.

 

I'm same, can't stand any leaks myself. Was almost going to replace it too , but I'm glad I left it alone as it seems fine now.

 

Should be warrantied for a year isn't it?

 

Well bear in mind metal does shrink in the cold. Lot of difference in AR cold and your cold. I know the amount of shrinkage is minute but an inch can be a mile some times. Very possible it will warm up and swell a little as well the teflon seals will soften and expand. I would see what happens for sure. And agreed I run a 1985 359 everyday, I can't stand even a seep drives me crazy.

 

I have a new waterpump for my c 13,for 2 months the pump was leaking,a big screw behind the pump was leaking,after fixing the screwl was ok for 5 weeks,after the same now were fixed again. I hope this time works longer,( THE problem is,to fix the screw better ,no space bewin,turbos,waterpump ,hoses...)
