Is a water pump part of the cooling system?
The water pump is the heart of the cooling system. It circulates the coolant through the engine, radiator and heater core. The coolant picks up heat generated in the engine by flowing around the cylinders. It also flows through passages in the cylinder head around the very hot combustion chambers.
What causes a water pump to leak coolant?
Water pumps can leak from 2 different places; the shaft seal or the water pump gasket. If the water pump bearings are starting to wear out they will allow the shaft to wobble and coolant will leak out.
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.
Can a cold water pump cause a head gasket to leak?
This could mimic a head gasket leak. Adding cold coolant to an overheated engine can cause thermal shock and create a seal leak even in a new water pump. Starting an engine during a water pump replacement before adding coolant could have the same effect.
What to look for when replacing a water pump?
Starting an engine during a water pump replacement before adding coolant could have the same effect. Look for a crack across either the seal face or the mating ring as evidence. Allow an overheated engine to sit and cool before adding coolant.
How can you tell if your water pump is leaking?
If it appears to be wet from coolant, you have a leak somewhere, possibly in your water pump, but other sources of leaking coolant could be radiator hoses, heater hoses, freeze plugs, gaskets, or the radiator itself.
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 causes a seal to leak on a water pump?
Adding cold coolant to an overheated engine can cause thermal shock and create a seal leak even in a new water pump. Starting an engine during a water pump replacement before adding coolant could have the same effect. Look for a crack across either the seal face or the mating ring as evidence.

What are the eight main parts to a cooling system?
The major components of the cooling system are the water pump, freeze plugs, the thermostat, the radiator, cooling fans, the heater core, the pressure cap, the overflow tank and the hoses.
Why are the lower coolant hoses so durable?
Note that because lower coolant hoses are exposed to heavy amounts of suction from the engine’s water pump, a resilient spring is wound around the inside of them to ensure the hose does not collapse and block the flow of coolant. Like most components of modern hoses, these springs are quite durable over the long term.
What’s the name of the fifth coolant hose?
Bypass returns are generally short in length and are often considered a “fifth hose”. Although not commonplace, some engines such as this BMW V8 position their coolant bypass pipes internally in difficult-to-reach locations.
