In the warm months of summer a cool blast of A/C is always a welcome relief, so it's a good idea to keep your vehicle's cooling system serviced for optimal performance. Two engines were available for the 2003 the Ford Taurus: the 155-hp OHV V6 Vulcan or the 200-hp OHC V6 Duratec. It is suggested that coolant be flushed and replaced once a year. The 2003 Ford Taurus calls specifically for r-134a refrigerant.
