In the 1990 model year, Mazda released a new compact vehicle, the Protege, which essentially was a four-door model of the maker’s existing entry-level vehicle, the 323. The 1998 Protege, three years after officially replaced the 323, came standard with a 92-horsepower, 1.5-liter four-cylinder engine. A 50-50 mixture of ethylene glycol-based coolant and water kept the 1.5-liter engine at an acceptable operating temperature. Mazda recommends draining and refilling the coolant on the 1998 Protege every 45,000 miles.
