Range Rover V8 Turbo Engine Overheating and Burnt Gasket: What to Do Next

Range Rover V8 Turbo Engine

When your Range Rover V8 turbo engine overheats—especially more than once—and the head gasket burns out, it’s a serious red flag that shouldn’t be ignored. Many car owners rush into quick fixes, but in high-performance engines like the Range Rover’s 5.0L V8, taking shortcuts often leads to bigger, more expensive problems down the road.

At Carmedis, we approach this kind of repair with a forward-thinking strategy built on precision diagnostics and long-term reliability.

1. Start with a Complete Engine Assessment

A burnt head gasket after two overheating events means the engine may have sustained internal damage. This can include:

  • Warped or cracked cylinder heads

  • Blown liners or block cracks

  • Oil and coolant mixing inside the engine

Before spending money on gasket replacement, a compression and leak-down test should be performed, followed by an oil analysis to detect coolant contamination. Only when we know the condition of the head and block can we decide if a rebuild makes sense.

2. Ignition Coils and Plugs

In some cases, the eight ignition coils are bad—a clear sign of heat or voltage stress. For stability and balanced performance, all eight coils and spark plugs should be replaced together. We also inspect the harness connectors and ECU wiring for any heat damage that could trigger future misfires.

3. Rebuild or Replace the Engine?

This is the big decision point.

  • Rebuild Option:
    Viable only if the engine block and heads are still structurally sound. This process involves machining the heads, replacing the head gasket, seals, timing chain, and cooling components. It restores engine integrity, but it can be cost-effective, risky, as it is not guaranteed.

  • Replacement Option:
    Installing a remanufactured or certified used engine often proves more reliable; it is expensive, but a good decision in the long run. You get a fresh start without inheriting hidden damage from the overheated unit.

At Carmedis, we evaluate both options for you—based on engine test results, mileage, and cost-benefit ratio.

4. Address the Root Cause of Overheating

Replacing the engine or gasket without fixing the underlying issue is a setup for repeat failure. We recommend:

  • Replacing the water pump, thermostat, and coolant hoses

  • Testing the radiator and cooling fan module

  • Conducting a pressure test and ensuring the cooling system is properly bled

This ensures consistent temperature control and protects your investment.

5. Prevent Future Damage

After repairs, prevention becomes the focus.

  • Use only OEM coolant and full synthetic oil (5W-30 or 5W-40)

  • Run a cooling system diagnostic every 6 months
