I have an 04 Suburban with the 8.1l. I want to drain and refill the radiator with new Dexcool......but why did GM do away with the drain. As far as I can tell, it looks as if I have remove the lower radiator hose. The hose is actually a special clip in style(not the normal hose clamp). It looks as if I am going to have to make a big mess to drain the radiator. Just wondering if any body has a better idea, or just pull the hose and let her blow...as neatly as possible.

 

Thanks in advance

Should be a drain cock hidden away on the driverside of the rad. Its in behind some plastic covers, you can really only see it if you have the vehicle on a lift.

Yeah, I had looked where there should be a drain. You can see where the casting is as well as where the drain hose should hook up. The factory left out the drill and insert the plug bit. That would be to simple.

May be an after market rad...I know every one I worked on has one.

 

Bring it to a shop man and get them to do the full flush and fill...much cleaner and less headache for you.

My '96 has a drain on the bottom drivers side, but when I needed to drain some coolant to change my water pump, I just removed the lower hose, and aimed it at a 5 gallon bucket. The petcock was behind all kinds of plastic I didn't want to remove (yes I know I'm lazy :P )

Mine has a thing that looks like where the drain hose should be, and even has the little plastic loop that the hose would be in when stored away. No hose and no logical way to open the plug.

My 2001 2500 4wd did not have one. (replacement radiator did when the trannie cooler started leaking I got a drain plug)

 

But my 1999 2wd does have one.

      I wasn’t commenting on your post. Certainly wasn’t arguing. I was making an observation on my long term experience with supposedly proper length of driving for proper heat cycles. Works for me. Although I have seen water or vapor come out of exhaust when vehicles weren’t run very long and shut off. It’s very humid in the morning. Then hot and humid.

      Not what I said but I can work with it anyway. Complete combustion produces CO2 and H20. When it's cold enough you can 'see' it as water vapor but it is always there and more so the better the tune up. It's physics, not an argument. In a cold motor when the cylinder jacket is below the condensation temperature the water goes to the pan and not the PCV system. Heating the oil moves it from liquid to vapor where it is removed by the PCV system. When and how much depends on temperatures. Of the air, the water and so on. It has little to with the humidity. Water is a combustion product.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      I can only guess as well that something was clicked on that brought you to the half ton choices by accident. By all means try again and chose the 3500 and sort out that its the cab and box configuration you want and choose four wheel drive ( rather obvious to have a transfer case ) and to make sure the dually isn't chosen. I find or at least did a couple of years ago when I was sifting through the options that it would sometimes jump ahead after choosing the series of truck and in this case 3500 and skip some of the other initial configuration choices and have to watch the heading bar and sometimes back up by choosing the first in the series of option break downs. I think sometimes the computer will remember items that were last chosen and skip over the first part. Anyway go through it all and depending on the trim level chosen and I think the LT is one that may fall into that where the option of having the 4 high auto transfer case can be chosen, where as a High Country doesn't show that option as it just comes with the fancier ( not necessarily better though in terms of potential problems ) transfer case but for sure both transfer case choices are equipped with high and low range in the HD truck segment. Like Newdude said who works at a dealership, its the half tons that are the ones that will come with the single speed unless certain options or trim levels are chosen that add the two speed transfer case but as your looking at an HD, you don't have to worry about that hot mess.    One item that at least didn't show up and not sure if it does yet or not in the HD options on the manufactures pubic website is the upfitter in cab switch option if one is desiring that. Unfortunately its not wired in at the factory but the panel with the switches is on the dash but the wiring harness to be installed gets tossed under the rear seat to be installed by whomever after the fact to complete the installation.

      Yesterday we brought home a 6yr  old Havanese dog from a nearby SPCA.  We've had her for 24 hours and we are delighted with how well she is adjusting to her new home.  It  was a huge decision to adopt a dog at this stage in our lives but we believe we made the right choice!   it was reported that her first 6 years were ones of neglect.  I think she's already realizing her life is going to get a whole lot better...  so is ours!
