Technical Specifications

1. Product Type: Integrated heater coolant manifold tube with OEM temperature sensor
2. OEM Brand: WAHLER Germany (Original Equipment Manufacturer)
3. Material: High-temperature reinforced engineering plastic (stock OEM); upgraded aluminum version available separately
4. Sensor Spec: 2-pin NTC coolant temperature sensor pre-assembled
5. Working Temperature Range: -40℃ ~ +135℃, resistant to high engine bay heat
6. Sealing: Built-in high-temperature EPDM rubber gaskets at all mounting flanges
7. Factory Inspection: 100% coolant pressure leak test + sensor signal calibration before shipment
8. Quality Standard: IATF16949 automotive OEM production certification

Core Functions

1. Circulate coolant between engine rear heater circuit and chassis crossmember cooling pipeline
2. Built-in temperature sensor feeds real-time coolant temperature data to vehicle ECU
3. Assist ECU to adjust thermostat opening, cooling fan speed and cabin heater output
4. Stabilize rear engine cooling loop pressure to avoid local overheating of cylinder bank

Common Malfunctions Resolved

• Coolant leakage at manifold cracks or flange gaskets leading to low coolant warning
• Broken integrated temperature sensor triggering P0117/P0118 temperature fault codes
• Weak heating output in cabin due to blocked manifold internal passage
• Engine overheating caused by coolant loss from cracked plastic tube
• Erratic cooling fan operation, unstable thermostat control from failed sensor signal

Product Advantages

1. Genuine WAHLER German OEM component, identical material, sensor calibration and dimensional accuracy as factory original spare parts
2. One-piece integrated design with pre-mounted temperature sensor, no separate sensor purchase required
3. High-temperature anti-crack reinforced plastic material, effectively avoid common OEM plastic pipe cracking failures
4. Complete matching OEM mounting gaskets integrated, eliminate extra sealing part procurement
5. Single part covers multiple interchange LR/AJ/C2Z OE numbers, greatly reduce warehouse SKU inventory
6. Plug-and-play installation, no cutting, bending or adapter modification needed

Package Includes

Installation Guidance

1. Fully drain engine coolant before disassembly; disconnect vehicle 12V battery negative terminal
2. Clean mounting flange surfaces to remove old gasket residue to prevent secondary leakage
3. Torque mounting bolts to Land Rover factory specified torque value evenly
4. Refill coolant, perform air bleeding procedure for full cooling circuit
5. After start-up, clear coolant temperature related fault codes with Land Rover dedicated diagnostic scanner
6. Road test to verify normal heater performance and no coolant leakage
