Water pump is leaking out the weep hole, you need a new water pump/

Customer reply replied 10 months ago
probable cause? -- not a weep but open flow when coolant is poured into radiator--
Technician: Curtis B., Technician replied 10 months ago

Bearing and seal bad in pump, can you move the shaft up and down?

not noticed -- belt still tight no noticed looseness
Technician: Curtis B., Technician replied 10 months ago

Did you remove belt and feel the pump?

Ask Your Own Medium and Heavy Trucks Question
Technician: Curtis B., Technician replied 10 months ago

Is the leak out of the pump. or elsewhere? Not a threaded hole, that plug has fallen out?

on the farm we have "dial up" service and flip phones -- am at McDonalds with the lap top -- best to contact here or on e-mail
Technician: Curtis B., Technician replied 10 months ago

I'm ok with lap top, that is what I use and prefer. It's site throwing out phone call request!

Customer reply replied 10 months ago
not out of threaded plug (which is closer to belt pulley)
Technician: Curtis B., Technician replied 10 months ago

Sounds like where weep hole would be.

Ask Your Own Medium and Heavy Trucks Question
Customer reply replied 10 months ago
weep holes are usually provided to allow atmosphere vent to ensure seals a required pressure drop across them -- does this imply a pump lip seal has failed ?
Customer reply replied 10 months ago
lip seal? quad seal? o-ring?
Technician: Curtis B., Technician replied 10 months ago

I think of weep holes a place for seals to leak and not let the coolant enter crankcase! Usually water pump seal and bearing are all one unit.

Ask Your Own Medium and Heavy Trucks Question
Customer reply replied 10 months ago
oil level as expected but will drain and ck for small amount of coolant -- don't want to stick rings!
Customer reply replied 10 months ago
is the seal/bearing a servicable item ? or complete pump assemble?
Technician: Curtis B., Technician replied 10 months ago

Pump assembly, more than likely for this engine.

It isn't a 3600 for sure -- but still expensive for market / vegetable farming!
Customer reply replied 10 months ago
part available in Morton parts depot
Technician: Curtis B., Technician replied 10 months ago

I assume it has to come from Cat?

Ask Your Own Medium and Heavy Trucks Question
Customer reply replied 10 months ago
serviced manual for torques, seal part numbers. etc? Not required from Cat but feel more comfortable if they ensure correct fit and function
Customer reply replied 10 months ago
Thanks for your understanding -- will take belt off tomorrow AM, ck oil for coolant, check for shaft fit -- possibly pull pump once I can ensure local dealer has gaskets (or I'll cut one myself) -- any point asking for an early hour failure cost adjustment? Where else is possible qualty parts source other than Cat in Morton Illinois ?? phone number?
Technician: Curtis B., Technician replied 10 months ago

Looks to have to come from a Cat dealer.
