Frequently asked questions

What does the coolant bypass tube do?
The coolant bypass tube routes coolant through the thermostat bypass path on the 5.0L V8 petrol engine (AJ133), serving the thermostat housing. It helps regulate warm-up and coolant circulation on the Range Rover L405 and Range Rover Sport L494.
Which vehicles and VINs does this bypass tube fit?
This coolant bypass tube fits the 5.0L AJ133 petrol Range Rover L405 (2013-2022) and Range Rover Sport L494 (2014-2022) within VIN range JA000001 to JA999999. Confirm your VIN, as cooling pipework varies across builds and engines.
Why does the coolant bypass tube need replacing?
The coolant bypass tube is usually replaced when it corrodes, splits or leaks coolant near the thermostat housing on the 5.0L V8. A leak here can lead to coolant loss and overheating, so it's renewed once a weep or crack appears.
