Womala Oil Cooler Tube Oe LR028136 for Land Rover Discovery 5 Range Rover Sport

Product Overview

The Oil Cooler Inlet Connector LR028136 is an OE-grade cooling system component engineered for 3.0L V6 and 5.0L V8 petrol engines (AJ126 / AJ133) in select for Land Rover and for Jaguar vehicles. This connector joins the water pump to the oil cooler, forming a critical junction in the engine cooling and oil temperature regulation circuit.

LR028136 is the current replacement part, superseding LR011997, AJ812249, and C2Z18658.

⚠️ Important: The factory plastic connector is a known failure point — it becomes brittle and cracks with heat cycling, leading to coolant leaks. Upgraded aluminium versions are available as a permanent fix, offering superior durability and heat resistance compared to the original plastic design.

Key Features

• Critical cooling junction – connects water pump to oil cooler, maintaining proper coolant flow and oil temperature regulation

• Upgraded aluminium option available – replaces failure-prone factory plastic with reinforced metal construction for enhanced durability and heat resistance

• Complete kit options available – some packages include gaskets, seals, and O-rings for a complete repair

• OE-grade quality – available as Genuine Land Rover, Rein, URO Parts, and other quality alternatives

OE Cross-Reference

💡 Note: LR028136 and LR011997 refer to the same oil cooler inlet connector. LR030593 is the oil cooler outlet pipe seal, and LR049370 is the water pump gasket — both are commonly replaced alongside this connector.

Technical Specifications

Vehicle Fitment

Engine compatibility (verify with VIN):

• 3.0L DOHC GDI SC V6 Petrol (AJ126)

• 5.0L OHC SGDI NA/SC V8 Petrol (AJ133)

⚠️ Important: This connector fits 3.0L V6 supercharged and 5.0L V8 petrol engines. Does not fit 5.0L V8 naturally aspirated applications in some listings — confirm your engine type and VIN before ordering.

Signs of Failure

• Coolant leaks – visible drips from the water pump or oil cooler area

• Low coolant warning – recurring need to top up the reservoir

• Engine overheating – coolant loss compromising temperature regulation

• Visible cracks or brittleness – plastic connector degradation from heat cycling

• Coolant residue – pink/white crust around the water pump area

💡 The factory plastic connector is a known failure point on AJ126 and AJ133 engines. It becomes brittle with age and heat cycling, leading to coolant loss and potential engine overheating if not addressed. Upgraded aluminium versions are strongly recommended for enhanced durability and to prevent repeat failure.

Critical – Verify Your VIN Before Ordering

Oil cooler connectors are VIN-, engine-, and model-year-specific. Provide your VIN – our team confirms exact compatibility before dispatch. We cannot accept returns for misordered parts without VIN verification.

💡 Installation Tip: Professional installation recommended. When replacing the connector, inspect all cooling system hoses and connections for wear. It is recommended to replace the water pump gasket (LR049370) and oil cooler outlet seals (LR030593) at the same time for a complete repair. Refill with OEM-specified coolant at the correct mixture ratio and bleed the cooling system thoroughly to remove air pockets.
