🔧 CFMoto Reservoir Tank Overflow Hose
📦 Part Number: 6AQV-180004-1001
⚙️ Reservoir Tank Overflow Hose · Coolant Drain Hose · OEM Spec
📍 Installation Location: Cooling system / Reservoir (expansion tank) to outside of vehicle
✅ Single unit · Premium heat-resistant rubber hose · Direct fit · Compatible with multiple CFMoto 450cc motorcycle models
This is a CFMoto OEM-spec Reservoir Tank Overflow Hose, part number 6AQV-180004-1001, sold as a single unit. This overflow hose is an important component of the engine cooling system, installed at the overflow port of the reservoir (expansion tank). It safely directs excess coolant — which expands and overflows when the system heats up — to the outside of the vehicle, preventing coolant from spraying onto the engine or body, while maintaining proper system operating pressure.
Over time, the original overflow hose may age, harden, crack, or deform due to high temperatures, vibration, and chemical exposure — potentially causing coolant overflow blockage, leaks, or hose disconnection. Replacing with an OEM-spec overflow hose is essential to restore cooling system overflow function and keep the engine compartment clean.
✅ OEM Quality Assurance: Manufactured strictly to CFMoto original technical standards. Made from premium heat-resistant, coolant-resistant rubber, with inner diameter, length, and connector dimensions identical to the genuine part, ensuring a perfect replacement and reliable overflow function.
This Reservoir Tank Overflow Hose (part number 6AQV-180004-1001, single unit) fits the following CFMoto motorcycle models:
- CF400-12H · 450SR
- CF400-16H · 450SR

• Hose shows aging, hardening, cracking, or deformation (visual inspection).
• Coolant leaks from the reservoir overflow port but does not flow out through the hose.
• Hose is clogged or kinked, preventing proper overflow drainage.
• Hose is disconnected or broken.
• Hose has lost elasticity when inspected during service.
If any of these occur, replace the overflow hose promptly to ensure proper coolant overflow drainage.
1. Confirm the hose is the correct 6AQV-180004-1001 matching the original.
2. Allow the engine to cool completely before working to avoid burns.
3. Remove the old overflow hose from the reservoir overflow port.
4. Clean the reservoir overflow port.
5. Install the new hose onto the overflow port in the correct orientation, ensuring a secure connection.
6. Route the other end of the hose to the designated outside position — ensure no kinks or blockage.
7. Check the hose routing to avoid contact with hot or moving components.
Installation is simple and DIY-friendly, but be cautious of hot coolant to avoid burns.
