The radiator is the central component of your Range Rover’s cooling system. Its fundamental function is to prevent the engine from overheating. Coolant circulates between the radiator and the engine. Through the cycle, it absorbs heat from the engine and dissipates it through the radiator.
When your Range Rover radiator leaks, it will lose coolant and become inefficient for cooling the engine. As a result, your Range Rover engine risks catastrophic damage. In a situation like this, you have only one option: to visit specialists entrusted with Range Rovers to replace or repair your radiator.
The Most Common Causes of a Radiator Leak
Corrosion
Your Range Rover’s radiator is under constant heat and pressure from the engine. As it ages, its parts start to deteriorate. The cracks resulting from corrosion form holes that eventually become large enough for coolant to seep through.
Wear in radiator hoses
Radiator hoses are synthetic rubber tubes that carry the coolant from the radiator to your Range Rover engine and vice versa. The hoses are subjected to the extreme environment within the engine compartment that eventually wears them out and causes them to leak.
Faulty radiator cap
A radiator cap might seem to be a non-issue here. However, it is crucial for the proper pressure within the radiator. If the radiator cap gets jammed, the pressure buildup may cause radiator weak hoses to crack or break. On the other hand, a loose radiator cap can cause the overheated coolant within the radiator to escape in a gaseous state. Additionally, the coolant might seep from underneath the loose radiator cap.
Radiator cap failure is a less common cause of radiator leak and is hardly noticeable. Inexperienced mechanics may not know and may not dare look at the radiator cap as they inspect your Range Rover. It is advisable to get your vehicle checked by our experienced professionals, who will examine every probable cause of your radiator leakage.
Worn Out radiator gasket
The radiator gasket seals the connection between the radiator and the coolant tank and can cause a fluid leak as it wears out. When you visit a repair shop, the mechanic will advise you to replace the gasket or use an alternative sealer to stop the leak.
Water pump failure
This is responsible for pushing the coolant between your Range Rover’s radiator and the engine. If the hoses, clamps, or seals connecting the water pump to the radiator break, they will cause leakage leading to water pump inefficiency.
Warning Signs of an Imminent Radiator Failure
- Engine is overheating: An overheated engine is a clear sign of inefficient cooling that may result from a leaking radiator. When your Range Rover’s engine overheats, the temperature gauge on your dashboard will read higher than normal temperatures. Consider taking your vehicle to a reliable repair shop for proper diagnosis and repair when you notice your Range Rovers engine overheating.
- A drastic drop in coolant level: Coolant levels drop gradually with time. However, a drastic drop indicates a probable coolant leak. If you fill the reservoir without a proper diagnosis, it won’t last long and may lead to engine breakdown.
- Rusty or corroded radiator: Coolant leaking from your radiator may cause its exterior to rust. Usually, you will notice corrosion in a particular area of the radiator. It is crucial to take your Range Rover for an in-depth examination if that is the case.
- Puddle underneath your Range Rover: A puddle of bright green, orange, or yellow fluid under your engine compartment may be coolant. It is best to pay attention since not all fluids under your vehicle are coolants. However, in whichever case, it is crucial to take your Range Rover to a qualified repair as soon as you possibly can.
