The performance of the Land Rover vehicle is attributed to its highly sophisticated engine, which is supported by a cooling system that keeps the engine running efficiently. The water pump is a vital component of the cooling system, which circulates coolant throughout the engine to maintain optimal temperature for engine functionality.
The water pump comprises components such as housing, impeller, shaft, bearings, seals, pulley, and weep hole. These components work together to pull and circulate the coolant with a pressure mechanism throughout the engine block and cylinder head. The coolant absorbs all the heat and flows into the radiator, where the heat is dissipated into the outer environment.
Factors Behind The Water Pump Failure in Land Rover
Bearing failure
Traditionally, the water pump is a mechanical component, and in modern Land Rovers, it is an electric and mechanical combination. The water pump features pulleys held by sealed bearings. The constant rotation over time and the strain from the serpentine belt’s activity eventually cause the bearings to wear out. This malfunctions the water pump, sometimes even causing it to seize altogether.
Seal and Gasket damage
The pressure mechanism of the water pump relies heavily upon the sealing ability of the seals and gaskets. If the sealing fails due to damage and degradation to the seals, then the pressure does not form properly. Thus, the water pump fails to work and shows signs of malfunction.
Impeller Damages
The impeller is the wheel that circulates the coolant throughout the engine bay. If the coolant is contaminated with dirt, debris, or metal shavings, then the impeller gets damaged by them. Additionally, degraded coolant that has not been changed promptly can cause corrosion to the impeller, resulting in impaired movement.
Improper Belt Tension
The serpentine belt creates the pump movement, which triggers the pressure to move the coolant. If the serpentine belt is too tight, it causes excessive strain, which breaks the pump. On the other hand, if the belt is too loose, it slips off the pump, halting pump activity.
Upon the malfunction of the water pump, the cooling system in the engine halts, causing overheating and a reduction in performance. However, if the issue is ignored, the overheating progresses to cause corrosion of engine parts, oil burning, internal component melting, and sometimes engine seizing.
Replacement of Land Rover’s Faulty Water Pump
If the water pump in the cooling system of a Land Rover becomes damaged, it is replaced with a new, original equipment manufacturer (OEM) water pump. The procedures for the replacement are as follows;
- Before working on the engine to replace the water pump, several safety precautions were taken. The hot engine was allowed to cool down, and if the engine belongs to a modern Land Rover, then its electric terminals are disconnected.
- Then, the engine is drained of the coolant or antifreeze by opening the radiator hoses.
- Then, the most time-consuming procedure was conducted, where the water pump was removed after disassembling the engine. Depending upon the model, the positioning of the pump could vary.
- The damaged water pump is removed, and the OEM-made water pump is installed in its place.
- Then, the engine bay is reassembled.
- After installing the engine, the cooling system is installed, the coolant is refilled, and the system is bled properly to remove any air bubbles that could disrupt the pressure mechanism.
