Review on OAW Engine Cadillac Corvette Pontiac by James Roper

08 Pontiac G8 GT 6.0L. Always try to use OE or better but need it ASAP and the price was good. Slight differences between OE and this water pump. The only thing to watch out for is the water pump assembly on the top left where it is thicker than the original one. Bolted well just need to be careful with the 3/8 vacuum hose on the top left where that water pump is thicker. The tubing becomes very brittle and will not seat the pump properly until it is moved. It is highly recommended to replace all radiator/heater hoses, thermostat and radiator cap when replacing the water pump.
