Airtex AW5043 Automotive Cooling System Water Pump

Airtex AW5043 is an OE-replacement water pump for GM’s 2.3L Quad-4 engines, delivering the coolant flow required to keep the engine at an optimal temperature. This direct-fit unit is designed for 2.3-liter four-cylinder Quad-4 applications and lists compatibility with 1988–1995 GM Grand Am and 1992–1995 GM Achieva models, matching original mounting points and belt drive. As part of Airtex’s OE Replacement Series, AW5043 is engineered to the same form, fit, and function as the factory pump, ensuring reliable cooling system performance and compatibility with common radiator, thermostat, and coolant passages. The part serves as a standard maintenance replacement to restore proper circulation in Quad-4–equipped GM passenger cars from that era, preserving engine cooling and helping prevent overheating caused by a failing water pump.
