What is Weephole water pump?

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. Automotive water pumps only have coolant seals, as the bearing is permanently lubricated.

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 does it mean when coolant leaks out of a weep hole?

If the oil seals are leaking, extra lubricant from the pump bearings will drip out of the housing through the weep hole. Without a weep hole, oil would leak into the coolant and/or coolant would be forced past the oil seals and contaminate the engine oil. So what does it mean when coolant or oil leaks out of the weep hole?

How can I tell if my weep hole is 45 degrees?

To check if your weep hole is in fact drilled at 45 degrees, simply stick a thin stick or ideally a straw inside the weep hole, aligning it with the surface of the hole. It will stick out enough so that you can measure / gauge the angle it makes with the pipe itself. Simply measure the angle with a drafting triangle or estimate it on sight.

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.

Why does my water pump have a weep hole?

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.

How big of a weep hole do you need for a sump pump?

The sump pump will not deliver effective results if the weep hole size exceeds or less than 3/16”. The best way of making the right-sized weep hole is to use a power drill. The weep hole is required in a sump pump to prevent air from being locked in the chamber of the impeller.

If the oil seals are leaking, extra lubricant from the pump bearings will drip out of the housing through the weep hole. Without a weep hole, oil would leak into the coolant and/or coolant would be forced past the oil seals and contaminate the engine oil. So what does it mean when coolant or oil leaks out of the weep hole?

What is a failure point on a water pump?

Water Pump Failure Points. Leaks are the most common sign of water pump failure, but what type of seepage are you seeing and what does it 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.
