GM Genuine Parts 25196027 Water Pump and Alternator Belt Tensioner — for Chevrolet Spark

Belt squealing, chirping under the hood, battery charging issues, or a Check Engine light caused by a slipping alternator belt — these are common signs that your belt tensioner is failing. The tensioner maintains correct tension on the water pump and generator belt at all times, ensuring the alternator charges properly and the water pump circulates coolant effectively . A worn tensioner can cause belt slippage, leading to reduced power transfer, overheating, and premature failure of the water pump or alternator .

This is a factory-original GM water pump and alternator belt tensioner (OE part number 25196027), specifically designed for the 2014–2015 Chevrolet Spark.

This is the same part sold at GM dealerships.
