Another fluid change,,,,,,,,,,,,,,,,,,,,,,,,,

Yeah, 5 years or 100k. Did mine a couple ago and doing the thermo's will top it off again.

your still putting those thermostats off.....along with the pump rub..........?

Can't find the thermos I bought. To pricey for another set. Yeah, guilty on the pump rub, like the lift and gears I have sitting here,,,,,,,,,,,,

Give him a break Nate, he has been building for a few months. Bet he finds stuff he hasn't even known was lost when he starts cleaning up after the build is done.

Let me borrow the thread just for a moment guys...

Yea...

So I changed the coolant out today. There are several techniques to remove the old fluid. I chose to slice through the small 5/8" lower hose and install a nipple and two clamps after I had drained about 3.5ish gallons. I had three good gallons in the bucket, a goodly amount on the ground and of course soaked up in my sweatshirt and hair.

Yea, Nate, the mud is from a mulch bed at the mall!

Here it is without the factory plastic clamp

Hey, someone is on my side. I have been cleaning slowly (another project) but did find I have enough ridge shingles from my garage to finish this room. 

I like that mod Don. Hard to believe they provide no coolant drain on a 50K truck!

Since I was spilling fluid everywhere I decided to spill a little diesel as well. With the Air Dog hummin' this valve houses a schrader that is used to bleed air from the fuel system. I purged it a little just to make things a bit messier.

So here is a couple dollars in parts needed to mod the lower hose to be able to drain fluid there

A double ended 5/8" nipple made for coolant systems and two 3/4" clamps

After installing the nipple, I wrapped the whole assembly with a sectioned radiator hose to provide abrasion protection to the adjacent lower big momma rad hose

Next I topped it up with Dexicool, warmed the engine up and topped it again, and again.

Trucks need to fill up to the "Max" line which is nearly completely full.

I am a bit over 50/50 dexi-H20. At 50/50 I would get protection to -34F which we have not seen here before. We did get down to -29, and some reported -30F, but that is extreme for here (A warm spell for polar bear Sam!)

Thats if your buying GM, ferd wants 80K plus, and they have now claimed the title of having the first 100k truck... We too will be driving our oldies but goodies until they turn to dust!

50/50 works for most.

I think I'm inbetween 70/30 and 60/40.
I shoot for -50 or so, can't go much more than 70/30 or it will congeal.
At -40 100% antifreeze freezes, no beuno, and odd.
I just don't want to wind up missing a digit or limb.  I can sometimes get in a hurry to get results.

I'm getting ready to change out the dog hair in the back seat next.

It was providing a protective cover for the carpet.

Don, It looks like that is just a splice for the hose, why not a ball valve or a T of some type?    Either way far better than getting to the three inch hose on the bottom side of the Rad and the kid pool method.  I?ll look at adding that next time I do mine.
I have changed mine twice since owning the truck in five years. First was 100k and second Cooling stack cleaning

Isn't that like a $200 hose? I should probably replace mine since it is 11+ years old and add a petcock there someplace.

Yup. Although the wife would make me get rid of my old trucks and besides I?m even more stupid than that. I?m about to install a pool.  There goes my truck money.
