What does a weep hole on a water pump mean?
What does a weep hole on a water pump mean?
A coolant leak coming from the weep hole is a sign of water pump bearing or seal failure. This weep hole often resides between seals that separate the oil side from the coolant side.
What causes coolant to leak out of a water pump?
The water pump comprises a number of gaskets that ensure the coolant stays sealed and that the flow of water is uninterrupted. However, with time these gaskets can deteriorate and become completely useless causing the coolant to leak out from under the water pump.
What causes the shaft of a water pump to fail?
Noisy shaft bearings are the second-most common reason for water pump failure. Most shaft bearings fail due to normal wear in the bearing or due to the normal oxidation of lubricant on the bearing surfaces.
Why did my well pump lose its prime?
A pump may lose its prime because of a bad foot valve and/or a leak somewhere in the water system. It is important to turn the electric off when you go to prime your well pump.
What happens to the engine when a water pump fails?
3. Engine is overheating. When the water pump fails completely, it will not be able to circulate coolant through the engine block. This results in an overheating situation and if not repaired or replaced quickly, can cause additional engine damage like cracked cylinder heads, pushed head gaskets, or burnt pistons.
Why is there a weep hole in my water pump?
If this is the case with your vehicle, it is best to have one of YourMechanic’s certified mobile mechanics look over your car for proper diagnosing. Note: Leaks at the weep hole or at the water pump gasket are typically caused by contaminated coolant (or dirty coolant).
What does it mean when your water pump is leaking?
Most water pumps have a “weep” hole, or a bypass hole that lets water flow through it in case the pump bearings and seals have failed. Dripping water or a rusty appearance at this location indicates a pump shaft or seal failure. You can also wiggle the water pump shaft back and forth, noting if it has excessive play.
Why is my outboard motor not pumping water?
If you see a stream of water pouring forth, the impeller is working. Shut the motor down immediately if you do not see a stream of water coming from the lower rear part of your motor’s top cover; the problem lies with the impeller, not clogged intakes or a clogged water stream fitting.
Why does my water pump have a hole in it?
Water pumps all come with a hole in them. They need the weep hole to warn you when seals are about to fail in the pump. The weep hole is intended to allow extra lubricant from the pump bearings to drip out of the water pump housing. Without this hole, the oil would be forced past the water pump seal and get into the engine coolant.
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.

Can a weep hole in a water pump be repaired?
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. “Auto Repair Shams and Scams”; Chris Stevenson; 1990

Where does coolant drop from a water pump?
When this happens, coolant will leak from the water pump and drop to the ground, typically in the front of your car and in the center of the motor’s location.
