You will have to have a special tool made by Kent Moore to remove the connectors. The number of the tool is J-43181. If you do a GOOGLE search, you will see the tool you need. Regards.

Go to the dealer. He'll get it for you. Otherwise you cpuld make something that would work remember its only 20psi's there. i would need a photo of the area affected and I could probablytell you how to fabricate something that will work.

SOURCE: know how to change the oil pump in my 1997 chevrolet SILVERADO?

The oil pump is in the the oil pan so you will need a new oil pan gasket and some form a gasket as well to put the pan back on, because you will have to take it off, you will see the oil pump a soon as you take the pan off, it will have a tube connecting to the pick up screen and to the block, remove bolts from the block and remove oil pump. be prepared the primming rod will probably come out too. itll need to go back of course, make sure seated in correctly because the primming rod runs off the cam. make sure the surface area for the oil pump gasket is clean before reinstalling new oil pump same goes for oil pan. after everything back together refill oil. It is best to test the oil pump before starting for your engine. the best way to do this is to remove the distrubuter if it has one if it has electronic ignition it will have a cap where the distributer went remove that and you will see the top end of the primming rod, fit appropriate socket on the primming rod and use a battery gun to spin, look inside oil fill cap and make sure you see oil flow or oil pressure on your gage if equiped, CAREFULL!!!!!! make sure the socket on battery gun has no way of falling off, or you will have to remove oil pan again to retrieve it.
Another way to prime pump is to disable igniton main power like remove the coil wire, or main power wire for electronic igniton so you can turn the motor over with out it starting, once again turn it over until you know you have oil pressure with the gage or through oil fill cap. put ignition back together start the car and once again confirm oil pressure. If every thing looks good your done Good luck

SOURCE: How to change heater core in a 2000 Chevrolet

I believe on this model 1500/2500 gas w/ac that you have to first evacuate the a/c system and then remove the HVAC module [fancy wording for the entire heater box assembly] then remove the core from it once you have the assembly out of the cab. I also believe its about a 6 - 7 hour job and not one you'd want to try on your own unless you have quite a bit of mechanical experience behind you as it's not an easy one to do. It's also very easy to damage the new core when reinstalling the assembly back in the cab which will truly wreck your day if that happens!
