Restore your engine's cooling efficiency with this Precision-Cast Coolant Filler Neck Assembly designed specifically for the Toyota Yaris 1.5L L4 engine platform. Constructed from durable PA66+GF30 polymer reinforced with 30% glass fiber, this component resists the thermal stress and chemical degradation that cause leaks in aging factory units. The assembly features an integrated thermostat housing pipe outlet and a hermetically sealed body to maintain system pressure, preventing air pockets and hot spots that trigger overheating. Engineered to match OEM tolerances, it provides a secure mounting point for your radiator cap without requiring adapter plates or hose modifications. Replace cracked filler necks quickly to stop coolant loss and protect your water pump gaskets from air ingress.

Benefits & Tips

  • Compare Before Buying: Yaris cooling systems frequently undergo revisions between model years. Always photograph your current part and check the embossed code against the OEM numbers provided to ensure a direct swap.
  • Clean Mating Surfaces: Thoroughly remove old silicone sealant and corrosion from the cylinder head and radiator connections. Any debris left behind can compromise the gasket interface and lead to seepage around the new metal-to-plastic joint.
  • Verify Hoses and Clamps: Since removing the filler neck often requires detaching coolant lines, inspect your rubber hoses for hardening or cracks during the exchange. Reusing degraded hoses on a new assembly increases the risk of unexpected leaks after repair.
