If your LAND ROVER has been running HOTTER THAN NORMAL, showing COOLANT WARNING LIGHTS, or struggling to maintain proper engine temperature, the THERMOSTAT may be one of the most important components to inspect.
The thermostat plays a critical role in your vehicle’s COOLING SYSTEM, helping regulate engine temperature and protect your engine from COSTLY DAMAGE.
At your trusted independent LAND ROVER SERVICE CENTER in GLENDALE, LOS ANGELES, SOUTHERN CALIFORNIA, we specialize in diagnosing and repairing LAND ROVER COOLING SYSTEM ISSUES using high-quality OEM PARTS designed specifically for your vehicle.
What Does the Land Rover Thermostat Do?
The THERMOSTAT controls the flow of coolant between the ENGINE AND RADIATOR. When the engine is cold, the thermostat stays closed to HELP THE ENGINE WARM UP QUICKLY. Once the engine reaches operating temperature, the thermostat opens and allows coolant to circulate properly. A PROPERLY FUNCTIONING THERMOSTAT helps:
MAINTAIN IDEAL ENGINE TEMPERATURE
PREVENT OVERHEATING
IMPROVE FUEL EFFICIENCY
REDUCE ENGINE WEAR
SUPPORT PROPER HEATER PERFORMANCE
PROTECT INTERNAL ENGINE COMPONENTS
When the THERMOSTAT begins to fail, it can stick open or closed, leading to MAJOR COOLING SYSTEM PROBLEMS and potentially EXPENSIVE ENGINE REPAIRS.
Common Symptoms of a Failing Land Rover Thermostat
Land Rover owners may notice several warning signs when the thermostat begins to fail:
ENGINE OVERHEATING
COOLANT LEAKS
TEMPERATURE GAUGE FLUCTUATIONS
POOR CABIN HEATER PERFORMANCE
CHECK ENGINE LIGHT ILLUMINATION
COOLANT WARNING MESSAGES
REDUCED FUEL EFFICIENCY
ENGINE TAKING TOO LONG TO WARM UP
Ignoring these SYMPTOMS can eventually lead to SEVERE ENGINE DAMAGE, warped cylinder heads, HEAD GASKET FAILURE, or complete COOLING SYSTEM FAILURE.
