About Engine Cooling
Water pumps, thermostats and housings, coolant hoses, gaskets, block heaters and heater control valves that keep the engine at the right temperature.
A failing water pump weeps coolant from the weep hole or makes a bearing noise, while a stuck thermostat causes overheating or a heater that never gets hot. Replace the thermostat and gasket whenever you replace the water pump.
