Review on Tool for Securing OTC Water Pump during Maintenance by Ricky Brooks

This tool is required when replacing the water pump on Ecotec engines only. Be careful not to overtighten the gear. Important!. It is very important that the tool is tightened so that the gear does not move. Don't overdo it. If it moves even slightly, the timing chain tensioner will come out from under the cover and there will be a howling sound when starting. Unfortunately I must have stumbled across it despite the puff. In this case, it will be necessary to remove the timing cover and readjust or replace the lower timing tensioner. Do not start the car as the chain is too tight and you risk damaging the control system. Be careful with this work. Have a 10mm deep magnet well ready to aid in removing and installing the studs.
