Check to see whether your vehicle is leaking water when the heater is on or if the air conditioner is running. If the air conditioner is running, you’ll notice a small amount of condensation. A tiny puddle is always present under your vehicle during normal operations.

Does A Water Pump Only Leak When Running?

If the engine is running, a coolant fluid loss can be caused by a faulty water pump. The impeller of the water pump can leak coolant. An engine block gasket seal or weep hole may also be to blame. A weep hole is a common safety feature found in many water pumps. The coolant or oil can escape from the water pump’s inside through this little hole. The internal oil seal will break if the oil seeps out of the hole. Internal water pump failure is indicated by coolant or water spilling from the weep hole.

How Long Will A Water Pump Last After It Starts Leaking?

Water pumps and timing belts both have similar average lifespans. It is typical for a water pump to last between sixty thousand and nine thousand kilometres (90,000 miles).

What Will Stop A Water Pump From Leaking?

A radiator or water pump stop leak product in liquid form must be poured into the radiator of your vehicle. The engine’s radiator is located up front.

Before you add the solution to your radiator, make sure your car is running. To put it another way, the stop leak product is merely a short-term fix. After that, you’ll need to get a new water pump.
