CAT waterpump diagrams

Hey SHC i dont have diagrams but i can tell you that it's a pretty straight forward job. Draining the coolant is what takes the longest hopefully you have shutoff valves that way its less of a mess. on the single turbo CAT the procedure is much easier than on the acerts. There is two bolts holding a neck on the oil cooler you loosen those and pry on it and depending on your truck you might be able to pull it from the top of the frame rail or through the bottom if not just lay it to the side and wait until you loosen the plate on the back of the pump . Then you remove the short hose on the thermostat housing and then the thermostat housing there's three long bolts that bolt on the head the rest hold the housing together next you remove the plate that's on the water pump and remove your lower hose clamps. Then finally there's six bolts i believe holding the water pump. Hope this helps

 

What he said.....but you don't have to pull the thermostat housing. Just rotate the pump...it'll come out.

 

I went through this problem a few times with the broken bolt. My local welder/fab guy welded a piece of steel angle to the alt bracket so it catches one of the lower thermostat housing bolts. This will stabilize the alt bracket and wont need that bolt into the water pump housing. I did this about 3 years ago.....no problems since.

wrong place, sorry

 

I'd be interested in a pic as well. Have the same problem with a MBN in a Western Star
