Need help, CM-870 EGR tuneup

[Waterloo]

Helping my buddy out here with his new Volvo with a very nice and healthy CM-870 with 540,000 miles on the odometer.

I told him when things thaw out to bring it over to the house, the neighbors should still be gone...

We need to do an overhead, drain and flush the coolant system, replace some of the metal coolant lines, pull the EGR valve and clean it up, etc... He paid $16,000 for this baby, financed $7000.

   

   

My question, what sensors does this motor have? I know about the altitude sensor, is there an iMap or Exhaust back pressure sensor, etc? Which EPA sensors does he have, and what are they called?

I told him when we have the top off, let's replace the Jake harness, the cam and crank timing sensors, oil pressure/temp, thermostat, go through it and do it once and right.

This guy has had such terrible luck mechanically with trucks that it is not funny. Bad luck just follows him around, and he can wrench and weld, he is not one of those guys, he is McGyver's son if you ask me, welding with battery cables and coat hangers to get his truck back on the road?

I told him to buy this truck, after seeing the photos I posted. He is happy so far, other than the fuel tank issue, still working on that.

Quickserve, my account is loaded with EINs, and it will take who knows how long to clean it out. I know my friend can do this, but I'm just sitting here and volunteered my services to help him out with the part numbers, etc...

And not looking for part numbers, just which sensors regarding the EGR system, nothing off the wall...
