This kit fits most domestic and import cars, light trucks, and Ford vehicles. Always check compatibility with your specific vehicle model.

Select the adapter that best fits the opening of your radiator or coolant reservoir. The kit includes several adapters; experiment to find the best fit.

No, always let the engine cool down completely before using this kit to avoid burns or injury.

Wash the funnel and adapters with water and mild soap after each use. Ensure all components are completely dry before storing them.

The kit is designed to work with pressure caps. Ensure a good seal between the adapter and the radiator opening.

Air pockets can cause overheating, erratic heater performance, and potential damage to the engine. The kit helps to prevent these issues.

The 45° elbow is used to fit on radiator caps that are placed at an angle, providing a better seal and filling access.

Ensure the correct adapter is used. Reduce the filling speed and monitor the coolant level more closely. Check for blockages in the system.

Double-check for leaks in the cooling system. Verify the thermostat is functioning correctly. Consider a pressure test to check for any leaks that aren't visible.

Try a different adapter. Consult your vehicle's manual for radiator cap type or coolant reservoir opening type.
