Coolant Reservoir Expansion Tank 5Q0121407A For VW GOLF MK7 GTI R Audi A3 8V

**When to Replace:**
If you notice coolant loss, a low coolant warning light, coolant residue around the reservoir, or a strong coolant smell near the passenger side or firewall, it may be time to replace the coolant reservoir. Replacing it promptly helps prevent engine overheating and protects engine longevity.

Features:

• 【Connector Upgrade】A 3mm hole is added near the coolant level sensor connector to allow excess pressure to vent, helping prevent potential damage to other electronic components.
  
• 【Installation Instructions】Ensure the car is on level ground and the engine is cool, (wait at least 2-3 hours after driving to avoid burns from hot coolant or components). Slowly open the cap to release any residual pressure. If the system is pressurized or hot, wait longer to avoid burns. Loosen the clamps on both the inlet and outlet hoses using a screwdriver or hose clamp pliers. Install the New Reservoir.
