Womala Thermostat coolant pipe LR049990 for Land Rover LR4 Discovery 5 Range Rover Sport

Product Overview

The Thermostat Tube LR049990 is a genuine OE-grade cooling system component engineered for 3.0L V6 supercharged and 5.0L V8 supercharged petrol engines (AJ126 / AJ133) in select for Land Rover and for Jaguar vehicles. This rigid coolant pipe runs from the thermostat outlet to the water pump, forming part of the engine cooling circuit that regulates operating temperature . The original plastic connector elbow is a known failure point — upgraded brass connector versions are available to address this .

LR048474 and C2Z28258 are superseded/interchange part numbers for the same tube .

Key Features

• Coolant routing – carries engine coolant between the thermostat housing and water pump 

• Upgraded brass connector option – replaces failure-prone plastic elbow to prevent leaks 

• OE-grade quality – available as Genuine Land Rover and quality aftermarket alternatives (Rein) 

• Direct-fit replacement – matches factory routing and connection points 

OE Cross-Reference

💡 Note: The plastic elbow connector on this tube often breaks, causing coolant loss and overheating. The Rein CHU0638 features an integrated brass connector as a permanent upgrade .

Technical Specifications

Vehicle Fitment

⚠️ Important: This tube fits supercharged 3.0L V6 and 5.0L V8 petrol engines only — it does NOT fit the naturally aspirated 5.0L engine .

Signs of Failure

• Coolant leaks – visible drips at the moulded connector or water pump area 

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

• Engine overheating – coolant loss compromising engine temperature regulation 

• Coolant residue – pink/white crust around the thermostat housing area

💡 The plastic elbow on this tube is a documented failure point — it becomes brittle and cracks, leading to rapid coolant loss and potential engine overheating .

Critical – Verify Your VIN Before Ordering

Coolant tubes are VIN- and engine-specific. Confirm you have the supercharged 3.0L V6 or 5.0L V8 — not the naturally aspirated 5.0L . 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. Consider upgrading to the brass connector version to prevent repeat failure. Inspect all hose connections and clamps during replacement. Refill with OEM-specified coolant and bleed the cooling system to remove air pockets .
