Frequently asked questions

What is the PIH100040 coolant hose used for?
The PIH100040 coolant hose carries coolant from the expansion tank to the fuel cooler rail on the Discovery 2. It feeds the circuit that uses engine coolant to regulate fuel temperature in the diesel return system. It's a moulded rubber hose specific to this routing.
Where does this coolant hose fit on the Discovery 2?
This coolant hose runs between the expansion tank and the fuel cooler rail in the engine bay of the Discovery 2 (1998-2004). The fuel cooler rail uses engine coolant to manage fuel temperature in the return circuit, and this hose completes that feed from the tank.
How do I confirm PIH100040 fits my Discovery 2?
PIH100040 fits the Land Rover Discovery 2 (1998-2004) from VIN 3A828206 onwards. Use your chassis number to confirm the build is at or after that VIN break, as earlier cars use a different hose for the expansion-tank-to-fuel-cooler routing.
Why do coolant hoses like this fail?
Coolant hoses typically fail as the rubber ages, hardens and cracks, usually at the tank and rail connections where heat and pressure are highest. Signs include coolant weeping, a sweet smell, or a dropping expansion tank level. A perished hose can split and cause rapid coolant loss.
