N14+ Water pump leaks

I once had a truck that we installed three pumps on before we got a good one. Haldex units. N-14.

 

where r u getting the pump from?

 

well i got one that wasn't from cummins and it last like 4 months. Bought one from cummins and havent had a problem since. I wonder what kind of pump they are using. funny thing about that n14 it seems to like genuine parts for some reason. A lot of the aftermarket cheaper parts have given me headaches.....just my 2 cents

 

There's also a copper tube behind it, when you have the water pump off, best to replace tube or get some o rings from the hardware store.
It is possible to get a defective water pump. You have to figure they are sitting around until someone needs them. Last one I had was close to 800,000 before it came off.

 

I got a remanufactured one from Cummins and it's been good for a year so far, I think it was around $300

 

I was taught that some coolant additives, in excessive amounts, could cause seal failures. If replacing a pump for that reason also always flush the block and use new juice.
With a gauge in the R.R. of the block, max RPM, low flows run about 52 PSI, the old BC about 30-35? and the N-14 is probably about the same. I never heard of high pressure being a problem and thank the seal area would be low pressure anyway, that gives you an idea if you want to test internal pressure.
Did see a man put three Cummins Recons on the same day and they all leaked. Seals were put in wrong. It happens.
