heres a link to my photo album when i relaced the cp3.

cp3 replacement pictures by 2500heavyduty - Photobucket

you will need an assortment of deep and regular metric sockets, 19mm crows foot. and a 27mm socket iirc for the cp3 gear and puller.

you will have to remove power steering bracket, altinator bracket, thermostat housing, coolant crossover tube, and all fuel lines in around the cp3. the greenish steel return lines can be unbolted and bent out the way for removal of the cp3.

there is 4 bolts holding the cp3 to the front of the engine, you removing it you will have to slowly wedge it out with screw drivers and pick it up and roll it out from the bottom towards you.

this details are in short i can explain better if you have q's

Put it back together today. Took 3 hrs. No extra bolts and its started right up!! Going to test drive tomorrow. Not a hard job, just have to remember where everything goes. Pics really helped.

Whats the best way to bleed the coolant system? I filled it up but want to make sure there isn't any air trapped. Thanks
