Installation Notes

Drain your cooling system completely before starting and clean the mounting surface thoroughly to ensure proper gasket seal. Have new coolant ready and take time to clean the mounting surface thoroughly – old gasket material or corrosion causes leaks. While you’re in there, inspect your belt tension, radiator hoses, and thermostat.
