Water Pump

[Moddedgtp]

I got a 02 GTP and i was wondering how hard it is to put in a new waterpump?? She went out today not bad i cant still drive it and it doesnt get old its just sparying coolant. My buddies dad checked it out hes a GM tech, and he said its for sure the waterpump!! Any tips or anyone got any directions on how to do it. He said its a little more diffucult being thats it's supercharged!! Thanks

It was pretty darn easy on the 3100.. so if the engines are anything alike it shouldn't be too hard. *Get a Haynes manual*

Notice

 

Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

UPDATE: It wasn't the water pump, it was the radiator hose. I guess his Gatorback belt for his supercharger was rubbing against it and cut it like a band saw.
