Stop Coolant Leaks Before They Stop Your Engine.
The cooling system is the most critical maintenance point for modern Land Rover 5.0L V8 and 3.0L V6 engines. Over time, the factory plastic cooling pipes become brittle from heat cycles, leading to sudden cracks, "Low Coolant" warnings, and catastrophic engine overheating.
