What is the weep hole on a water pump for?
A weep hole is a small hole on the bottom of the water pump. Its main purpose is to warn you when the pump’s seals are about to fail. The weep hole sits between the oil and coolant seals. If the oil seals are leaking, extra lubricant from the pump bearings will drip out of the housing through the weep hole.
Why do manufacturers put a tell tale hole at the bottom of the coolant pump?
Water Pump. There it circulates and eventually exits back down through the propeller to help keep it cool from the outboard’s exhaust. A telltale hole emits a small, visible stream of water after it has passed through the powerhead, to help indicate that cooling water is flowing.
Does a water pump use centrifugal force to circulate coolant?
Coolant follows a circulation path that begins with the water pump. The water pump’s impeller uses centrifugal force to draw coolant from the radiator and push it into the engine block. Pumps are usually fan, serpentine timing belt, or timing chain driven.
Where does the coolant leak from a water pump come from?
My leak appears to be coming off the back side of the pump housing, but originating above the area that i can see with a mirror. Surely somebody out there in cyberspace has seem the dark side of the moon behind the water pump and could direct me on this.
What should I do if my water pump is leaking?
Fill with coolant. Start the engine and look for any leakage at the pump housing or hose locations. A “weep” hole leak, or leak underneath the water pump, will indicate a water pump failure. There is no quick fix for this problem. A new water pump replacement must be performed for this symptom, as there will be no remedy to stop this type of leak.
What causes a water pump seal to leak?
Belt tightness has some play in the deal of a water pump failing prematurely so don’t over tighten your belts, that will take it easy on the bearing so it doesn’t wear out and let the shaft wobble, which will make the seal leak to start with. Trying to be helpful, not a bummer.
What to do if your water heater is leaking coolant?
If a small leak appears in this area, you can re-torque the bolts according to manufacturer’s specifications. This can stop a very small leak. As an added precaution, make sure the heater hose and lower radiator hose clamps have been tightened, using the appropriate screwdriver or small socket.
What to do if your water pump is leaking coolant?
Look for any signs of leakage at the edges of the pump housing flange where it connects to the engine block. Make sure all of the water pump mounting bolts appear intact and that none have run out or disappeared. If a small leak appears in this area, you can re-torque the bolts according to manufacturer’s specifications.

What’s the best way to test for coolant leak?
You’re best bet for testing is a coolant pressure tester, pump it up to 15psi or so and check for leaks. Letting it sit and idle, or even a short drive isn’t always enough time for it to build enough pressure to show a leak. Yeah when I said under the cap I meant rad cap.
Why is there a hole in my water pump?
It’s the pump, just like mine. There is a “slight” chance its just a bolt but don’t hold your breath. Belt tightness has some play in the deal of a water pump failing prematurely so don’t over tighten your belts, that will take it easy on the bearing so it doesn’t wear out and let the shaft wobble, which will make the seal leak to start with.
