Womala Water Tube LR092992 for Land Rover LR4 Discovery Sport

Product Overview

The Coolant Crossover Pipe LR092992 is an OE-grade engine cooling component engineered for select for Land Rover and for Jaguar vehicles equipped with 3.0L V6 and 5.0L V8 supercharged petrol engines (AJ126 / AJ133). Also known as a thermostat top crossover hose or water outlet pipe, this component diverts coolant between the cylinder heads and thermostat housing, playing a critical role in engine temperature regulation.

The factory plastic pipe is prone to cracking and failure due to heat cycling. Upgraded aluminium versions are available as a direct-fit replacement, offering improved durability and resistance to warping compared to the original plastic design.

Key Features

• Coolant crossover function – diverts coolant flow between cylinder banks and thermostat

• OE-grade quality – manufactured to original equipment specifications

• Upgraded aluminium option available – replaces failure-prone plastic with reinforced metal construction

• Direct-fit replacement – drop-in installation with pre-installed gasket on aluminium versions

• For 3.0L V6 & 5.0L V8 supercharged petrol engines – AJ126 / AJ133 engine families

OE Cross-Reference

💡 Note: LR090630 is the upper crossover pipe and LR092992 is the lower crossover pipe in the pair. Some kits include both pipes together.

Vehicle Fitment

⚠️ Important: This coolant pipe is specifically for 3.0L V6 and 5.0L V8 supercharged petrol engines – not for naturally aspirated V8, diesel, or 2.0L variants. Some applications have VIN-specific fitment.

Signs of Failure

• Coolant leaks – visible drips from the crossover pipe area

• Engine overheating – coolant loss causing temperature issues

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

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

💡 The factory plastic crossover pipe is a known failure point on AJ126/AJ133 engines. Upgraded aluminium replacements are recommended for enhanced durability.

Critical – Verify Your VIN Before Ordering

Coolant pipes are VIN‑, engine‑, and model‑year‑specific. Some applications have VIN cut-offs and left/right or upper/lower variations. 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 crossover pipe, inspect all cooling system hoses and connections for wear. Replace coolant with OEM-specified fluid at the correct mixture ratio after installation. Aluminium versions come with pre-installed gaskets for easier installation.
