The GM WaterPump Holding Tool, No. 6616, from OTC, an SPX brand, holds the timing chain in place so the water pump on GM 2.2L and 2.4L EcoTech motors -- found in Chevrolet, Oldsmobile, Pontiac and Saturn platforms -- can be removed for service without affecting the timing. The holding tool allows easy application regardless of timing-chain orientation, and services GM vehicles from 2002 to current models.
