Optimized Heavy-Duty Structural Design

1. Multi-layer reinforced EPDM rubber main hose body: Excellent resistance to high-temperature antifreeze corrosion, anti-hardening and anti-cracking under long-time extreme temperature circulation
2. Independent thin metal auxiliary vent branch pipe: High rigidity, anti-vibration friction damage, stable air exhaust performance
3. Built-in integrated fluorine rubber sealing rings at both quick connectors: Long-term stable sealing performance, effectively avoid coolant seepage from joint gaps
4. Pre-positioned fixed buckle limiting grooves: Lock pipeline firmly on engine bay brackets to eliminate pipeline shaking abrasion
5. Complete one-piece pre-assembled hose unit, matched with original style locking clips for direct replacement without extra accessories

Core Engine Cooling Protection Functions

1. Balance coolant liquid volume expansion caused by engine temperature rise, prevent coolant overflow loss from auxiliary water tank
2. Discharge trapped air bubbles inside the whole cooling circuit to eliminate air lock and avoid local engine overheating
3. Buffer pressure fluctuation of cooling pipeline during cold startup and high-load off-road driving
4. Guarantee smooth coolant circulation of heater core to supply stable hot air output for cabin heating in cold winter
5. Reduce excessive pressure impact on auxiliary water tank assembly to extend the service life of expansion tank

Common Solvable Vehicle Faults

• Coolant liquid level drops continuously after regular antifreeze refilling
• Coolant malfunction indicator light repeatedly lights up on instrument panel
• Engine temperature rises abnormally when driving slowly in heavy traffic
• Weak and unstable hot air blown out from vehicle air outlets under low temperature
• Visible wet coolant stains and scaling residue around auxiliary water tank pipeline joints
• Abnormal engine temperature fluctuation caused by air lock in cooling loop

Brief Step-by-Step Installation Guide

Required Tools

1. Park vehicle on flat ground, shut down engine and wait for full cooling to prevent scalding from hot high-temperature coolant.
2. Lift vehicle and locate the overflow hose connected to auxiliary water tank, release quick locking clips on both pipeline ends.
3. Pull down the aged original coolant hose slowly, collect residual antifreeze into sealed container.
4. Wipe clean expansion tank and radiator connecting ports thoroughly, remove aging rubber gasket debris and coolant dirt stains.
5. Coat thin layer of sealing lubricant on the gaskets of new LR014567 water pipe, insert two-end quick connectors until hearing "click" locking sound.
6. Install fixed limiting buckles to fix pipeline on engine bay mounting brackets to avoid vibration friction.
7. Refill fresh matching Land Rover special coolant into auxiliary water tank, start engine and idle for 10 minutes to fully bleed air from cooling circuit.
8. Carefully inspect all pipeline joints for coolant leakage, confirm dashboard coolant fault warning light stays off during test drive.
