Product Description

The Behr Expansion Tank will work with Mercedes 450SLs from 1973, 1974, 1975, 1976, 1977, 1978, 1979 and 1980. The car's Expansion Tank is a pressure vessel that is designed to allow antifreeze and air within a coolant system to expand due to an increase in temperature. The Expansion Tank can fail due to harsh weather or wear and tear; when this happens a new one needs to be installed to maintain the car's cooling systems in the best condition. Without an Expansion Tank on a vehicle, the coolant that is discharged by pressure in the coolant system would leak out of the car which can be harmful for the planet. You should inspect antifreeze levels in the Expansion Tank often because drops in your car's antifreeze level indicate that there is a leak in the car's cooling system. Your Expansion Tank allows the gas in the radiator to swell with the rising temperature and rising pressure. Mercedes 450SLs from 1973, 1974, 1975, 1976, 1977, 1978, 1979 and 1980 will work with this Expansion Tank. Other makes and models probably will not be compatible, and this Expansion Tank is not intended to be installed in those models.
