Possible Sources of Leaks:
* Water Pump: The water pump is a common point of failure. If the seal is worn or damaged, it can leak coolant.
* Head Gasket: A blown head gasket can allow coolant to mix with oil and leak into the combustion chamber.
* Radiator: A crack or hole in the radiator can lead to coolant loss.
* Hoses: The hoses that connect to the radiator, water pump, heater core, etc., can crack, become brittle, or develop leaks over time.
* Thermostat Housing: The thermostat housing can leak if the gasket or seal is damaged.
* Heater Core: Leaks in the heater core can cause coolant to leak into the cabin.
* Engine Block: Cracks or corrosion in the engine block can lead to leaks.
* Expansion Tank: Cracks or damage to the expansion tank can cause coolant loss.
How to Narrow Down the Problem:
1. Observe the leak: Where exactly on the back of the engine is the leak coming from? Is it a steady drip, or a more intermittent leak? What color is the fluid?
2. Check the engine oil: Look for any signs of milky or white fluid in the engine oil, which could indicate a head gasket leak.
3. Inspect hoses and connections: Visually check all the hoses and connections for cracks, leaks, or loose clamps.
4. Look for coolant in the cabin: If you see coolant leaking into the cabin, the heater core is likely the culprit.
Important Notes:
* Safety First: When working on a vehicle, always disconnect the battery and wear appropriate safety glasses and gloves.
* Professional Assistance: If you are not comfortable diagnosing or repairing the leak yourself, it's best to take your Range Rover to a qualified mechanic.
