Installation Position

Optimized Heavy-Duty Structural Design

1. Reinforced multi-layer composite pipe body: High temperature and coolant resistance, effectively avoid swelling and cracking under long-term 100°C+ working temperature
2. Integrated molded quick-fit plastic connectors: Perfect sealed fit with expansion tank and engine pipe joints, eliminate leakage risk
3. Built-in high-temperature fluorine rubber sealing gaskets at both ends: Anti-aging, anti-corrosion, maintain stable sealing performance for long service life
4. Pre-shaped fixed clip positioning grooves: Firmly lock the pipe to engine bay brackets to prevent pipe vibration friction damage
5. Complete one-piece pre-assembled coolant pipe unit, ready for direct replacement without extra fittings

Core Engine Cooling Protection Functions

1. Transport overflow coolant between expansion tank and engine circuit to stabilize overall coolant liquid level
2. Discharge air bubbles trapped in the cooling system to eliminate air lock and avoid engine local overheating
3. Buffer pressure fluctuation inside cooling pipeline during engine cold start and high-load operation
4. Prevent coolant overflow loss caused by thermal expansion of high-temperature coolant
5. Ensure smooth circulation of heater core coolant to guarantee stable warm air output in winter

Common Solvable Vehicle Faults

• Coolant liquid level drops frequently with invisible leakage points
• Coolant warning light pops up on dashboard repeatedly after refilling fluid
• Engine overheating occurs during high-speed driving or traffic jams
• Weak hot air blowing out from heater vents in cold weather
• Visible coolant stains and wet marks around expansion tank pipeline joints

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 coolant.
2. Locate the original overflow pipe connected to the expansion tank, release the quick-lock clips on both pipe ends.
3. Pull out the old cracked coolant pipe slowly, drain residual coolant into a sealed container.
4. Wipe clean the expansion tank and engine pipe joint ports, remove aging rubber gasket residues.
5. Apply a thin layer of sealing lubricant on the gaskets of new 7P6122447N coolant pipe, align and insert two-end connectors firmly until hearing "click" lock sound.
6. Install fixed clips to lock the pipe on engine bay mounting brackets to avoid vibration shaking.
7. Refill fresh matching coolant into expansion tank, start engine and run idle for 10 minutes to bleed air from cooling circuit.
8. Check all pipe joints carefully for coolant leakage, confirm dashboard coolant warning light stays off.
