Upper Radiator Hose
Direct Fit
Overview
Land Rover Discovery 4 and Range Rover Sport owners running the 5.0L supercharged V8 petrol engine demand cooling components that can handle sustained high-temperature and high-pressure cycles. This radiator top hose (part number LR013681) is the OEM upper hose assembly connecting the engine block to the radiator inlet—a critical junction point under continuous thermal stress.
OEM-specification rubber compound resists degradation from coolant additives, engine oils, and external engine bay heat. The hose features reinforced internal construction to maintain integrity at 22 psi+ operating pressure typical of supercharged TDV8 engines, preventing coolant leaks that compromise temperature control and risk engine damage.
This is a direct fit replacement engineered to identical OEM dimensions and connection points. If your hose shows signs of weeping, cracking, or has failed previously, replacing it now eliminates cooling system reliability concerns before they become costly engine issues.

Installation Notes
Difficulty: Intermediate | Time: 45–60 minutes
-
Safety first: Allow engine to cool fully. Disconnect the negative battery terminal. Open cooling system pressure cap carefully (wear gloves; fluid may be hot).
-
Drain circuit: Position a drain pan under the radiator. Loosen the radiator drain plug and allow 20–30% of coolant to drain. This reduces pressure on hose connections during removal.
-
Remove old hose: Locate the upper radiator hose running from engine block to radiator inlet. Unbolt any hose retaining clips or brackets along the engine bay. Carefully twist and pull the hose free from both connection points. Note the routing path.
-
Clean connections: Inspect the radiator inlet and engine block fitting surfaces. Wipe clean with a lint-free cloth. Remove any scale or residual rubber debris.
-
Install new hose: Align the new hose to match the original routing. Push the hose firmly onto both connection points until fully seated. The hose should not move when pulled moderately.
-
Secure routing: Re-attach all hose clips, brackets, or retainers. Ensure the hose does not contact sharp engine components, high-heat surfaces (turbo, exhaust manifold), or moving parts.
-
Refill coolant: Pour the original or OEM-equivalent coolant back into the expansion tank to its full mark. Run the engine at idle for 3–5 minutes to purge air pockets. Monitor temperature gauge.
-
Final check: Allow engine to cool. Inspect both hose connections for weeping. Top up expansion tank if needed. Reconnect battery terminal.
⚠ Critical: Do not operate the engine with a dry cooling circuit. Always refill with OEM coolant (Pentosin G12 or equivalent) to specification. Failure to refill risks air locks, overheating, and catastrophic engine damage. If you see coolant loss within 48 hours, stop driving immediately and inspect for leaks.
