Your vehicle’s water pump is one of the most important parts of the engine. To stay running, it is crucial to maintain engine temperature. The water pump continuously circulates coolant through your vehicle's engine and back through the radiator, in order to prevent overheating.
We recommend replacing your engine's water pump when the timing belt is serviced, or immediately if a leak or malfunction is detected. Refer to your owner’s manual for timing belt service intervals. When a water pump fails either by leaking coolant or becoming unable to circulate coolant, the result is engine overheating.
Driving a vehicle with an overheated engine will result in engine failure, requiring very costly repairs and even complete engine replacement. From a safety standpoint, a water pump failure won't likely pose a problem for other motorists, but it could leave you stranded with no warning. From an environmental point of view there is significant impact. Leaking engine coolant is poisonous and could be ingested by children, pets and other animals.
