Beck/Arnley 131-2158 High Performance Water Pump Replacement for Ford, Chevy, Dodge - Perfect for Engine Cooling System Repair & Maintenance

This after market water pump fits my 2000 Mazda Protege 1.6 engine perfectly and the impeller appears to be more robust compared to the original water pump. The only reason I did not give this product 5 stars is because the provided literature only talks about replacing a traditional water pump on an old Detroit-made truck or car, which is connected directly to the fan behind the radiator. Also, there is zero info/diagram provided about the included black rubber 'thingie' or the 'o' ring.When you order this replacement part, I strongly recommend that you order a replacement timimg belt, timing belt tensioner, upper and lower radiator hose and thermostat and antifreeze. Get a flush kit and flush _before_ you pull the old water pump. Do not attempt to replace this stuff without a repair guide written specifically for the make/model car.
