Yes mine has the screen

Thanks, I might just order the part and put the screen in so I don't have to take the dash apart.

Visited the Valiant Air Command museum in Titusville, Florida the other day, 230 mile round trip or so, averaged 18.4 mpg on 93 at 71 mph. Lots of torrential rain on the way back.

Awesome place, great representation of aircraft including a couple of MIGs. While I was looking at a Mig-15 and an F-86 Sabre, another Sabre flew over the airfield! That was cool. Many of the aircraft are in flying condition. It's a weird thing, seeing many of those birds brought tears to my eyes, don't know why but they did.

If you love military aviation and you're nearby with a couple hours to spare, go!

Just got the BlackStone Labs report back. 2018 and 2019 were on regular Mobil One oil, the last two reports were using ACDelco full synthetic.

So I just installed the recirc actuator. That was a pain in the wrist…..my left arm feels like it went hands on with an angry feral cat.
Did it through the glove box. Funny thing it still steps when it goes to recirc ?

I did it through the airbag hole, much easier on hands and back! Still waiting for the other one to arrive and will take a reading and video.

The bracket and bolts over the battery is starting to rust. The Hood's rear weatherstrip must've shrunk at least 4 inches and needs replacing. It's been discontinued (15200240) and it does not appear that the aftermarket makes them yet. RockAuto seems to sell the material by the foot but there are so many choices it's confusing to me. The Sierra runs a different part number.

Chris, I remember you replacing yours, was it aftermarket or from one of your junkyard strolls?

Ok, just replaced the passenger side temperature actuator and took a video of the recirculate door in operation for you. It operates smoothly in normal operation and moved in steps when controlled by the Tech-2.

For those that come along later looking to replace an actuator:

It's an easy job with the right tools. Use a 10mm wrench to disconnect the negative cable on your battery. Then use a trim tool to remove the trim panel above the radio stack, it is one long piece, so be gentle and don't bend it under the AC vents! Once loose, flip upside down and disconnect the DIC connector and put it on the rear bumper. Now take a 7mm socket and remove the screw holding the right AC vent in place, there is one clip on this piece, use your trim tool to release it. Plop it over on the driver's seat.

Take a 10mm socket and a long extension and remove the 4 bolts securing the passenger side airbag. Now take your pry tool and gently pop loose the tabs on the airbag's sides first and then the portion in front of you and then gently lift it up and set it down askew on the dash. Pull the orange keeper out of the yellow airbag connector and you might use a small flat blade screw driver to help release the connector. Now you can put the airbag module on the driver's seat.

It's wide open now to replace the Recirculate Actuator or the Passenger Side Temperature Actuator. They both use the same part numbers and both are printed on the same box, 15-72971 or 89018365. I did not remove the red keeper prior to removing the connector from either actuator. Just pried up gently on the tab and lifted the connector away. On the Temperature Actuator, I removed the connector after getting it loose from its position. Take a 5.5 millimeter socket and remove the screws on either side of the actuator.

The doors that the actuator's manipulate are slotted, so keep that in mind when installing the new actuators. Installation is the reverse.

Trim Pry Tool
Pick or Small Flat Blade Screwdriver
10mm wrench
10mm socket - 1/4 inch drive
7mm socket - 1/4 inch drive
5.5mm socket - 1/4 inch drive

On a side note, if you are a thin contortionist with incredible surgeon like dexterity who likes to swear alot and have scratched up wrists and hand cramps.....it can be done through the glove box with just a 9/32 socket and small ratchet.

My kids said, "Hey Dad, you're bleeding!", somehow I cut my left hand and scratched up my right, near both index fingers! LOL

Always good to have alternate ways of getting things done, thanks!

Wow! My wife is now complaining that the AC is too cold! The change was so gradual that I did not notice the degradation in performance of the AC until about a year or so after it began. Now I remember how nice the chill coming out of the vents was and is again now that we have replaced the Recirculate Actuator! I can run the AC at 68 instead of 64 again like when I first bought it. Wow! My wife was driving the truck for a few days before I got some seat time yesterday and today.

Just passed 174K the motor runs like a top and the suspension and tires make the ride feel like we're riding on clouds.

Going to start the 14-bolt axle work soon and make the swap in September or October.

Sounds like a nice winter months project! That said, in Florida, that can be 3 days in late January or a random couple days in February-otherwise, its summer! That place is like having Malaria-hot or cold with no in between! Good luck with the axle swap though-will be a great upgrade!

Took a little drive on the way home from my church tonight. Wife will be using the truck tomorrow so I refueled it so she won't have to. Alcohol content on this Chevron 93 is next to nothing, in fact, it was at zero after 18 miles.

The trims are climbing once again at idle. Over -10, the passenger side is worse. Maybe I should pony up and buy a smoke machine finally? Speaking of, the Torque App says the emissions system is still "not ready" whatever that means. No codes, no recent codes for the engine side in a long while.

Call Guiness Book of World Records, on level ground at 65 mph she was delivering 21.5 mpg and creeping higher until we hit the "hills". The closest the truck came to that with the KO2s was 20.4 mpg, the average was 19.9 mpg back then. She does this regularly now, sometimes more with a tailwind.

Stopped at a light just off the highway, felt a momentary shudder, idle didn't drop, lights were steady, might have been a truck shaking the bridge we were on, just mentioning it in case something pops up in the future and you know how my memory is!

Been thinking about 3.73s, 5 angle valve jobs and camshafts lately...

The USS Orleck is a WWII era Gearing class destroyer that served in Korea and Vietnam and into the 1980s before being retired. She then served with the Turkish Navy and was returned to the United States for use as a museum ship. She was recently overhauled and will soon be open for tours in Jacksonville, Florida.

Since starting the fuel log in late 2017, we've not driven the truck continuously on a tank of gasoline such as when on a road trip. There are always stops involved and long periods of idling. This one wasn't perfect either but it's a start!

Knowing the Orleck was docked right in front of the Hyatt in Jacksonville, I had it in my head to make a midnight run to see her and run the test while my sleep schedule was out of whack again. This allowed me to basically pull right up next to the ship without leaving the truck, which is why this fat man even considered the run!

The truck was refueled earlier in the day and used to pick up groceries and then around 1 AM my youngest daughter and I set off for Jax. Immediately after refueling, the truck was getting 21+ mpg at 66 mph. Early on in the trip she delivered 20 mpg at 65 mph, 18.5 mpg at 70 mph and 17.4 mpg at 75 mph after nine miles for each leg.

We stopped at a rest area then later at Buc-ees in Daytona then on the way back grabbed breakfast at Bojangles in Saint Augustine, all the while never shutting off the engine. The truck was burning Chevron's 93 octane gas with no alcohol detected in it. Fuel trims were zero for the most part at speed but jumped to -13 and -17 when idling, something clearly is amiss again.

That tank of gas lasted about 9 and a half hours for 515.2 miles. We burned 27.2 gallons for 18.9 mpg with an average speed for that tank of 55.4 mph. Could have gone a little further with 4 gallons of gas left aboard! Cruise control was set for 67 mph.

The only other tankful of fuel to average over 55 mph was a run we made on E85 once that delivered 13.7 mpg on the KO2 tires. The truck is now wearing Michelin Defenders.

Curb weight started out at around 6,700 pounds and she never downshifted to cross a bridge and rarely even unlocked the converter to do the same. Good torque!

Jaime and I had a great trip, she was an excellent DJ and even put up with my oddball music requests!

Was she berthed in Lake Charles, LA previously? I’m pretty sure I’ve been aboard her there.

Yes! She was on display or go on display in Texas and had trouble getting a berth, then she broke loose in a hurricane and suffered some damage. Somewhere along the way she was on display for a time in Louisiana and then went back to Texas to be drydocked and overhauled and then was towed to Jacksonville.

She arrived before her permanent berth was ready, just a few hundred yards from in front of the hotel. Looking forward to taking a tour aboard someday.

I forgot about the hurricane. Yep, same ship. I’m glad to see she’s being conserved. There was still a lot of Turkish markings all over below decks when I was aboard.

Based on YouTube's Project Farm channel review of pressure washers, I purchased the Caterpillar 1800 psi electric pressure washer.

Works pretty good, we tested it out on the Sierra and are pleased with it. Looking forward to see how it does on the black Yukon. No leaks at any of the fittings!

It comes with 5 different nozzles, 4 quick disconnect types and one attached to the soap bottle. We tried out the white for most of the wash and then the green. If you get too close it'll lift the paint. I ran the red, the most powerful on some stains on the driveway, some disappeared lickety split, others took more effort.

This will be good to clean the engine bay and maintain the cars with, making quick work of car washes I think. We used our Meguiar's Gold soap.

 

[swathdiver]

Pressure washer working good on the Yukon as well of course. I still pull out the long brush to get the stubborn bug guts off the bumper cover and grill, mirror caps and windshield.

Went into the hospital again on Monday and got out Friday a few days after surgery again on Tuesday. Been to the hospital so often lately the staff is beginning to recognize me and I them! No slackers this time. Some of the newer people were absolutely hilarious.

Tried to buy the Harbor Freight 26" tool chests in Orange. Drove 80 miles to the store that had both in stock only to be told to come back later as they were too busy to get them down off the shelf. By that point my medical condition had deteriorated and I could no longer drive, the kids picked them up in Red for me at the local HF and put them together. Boy is this thing huge! It's deeper than expected even though I knew the specs going in, it will hold a lot more tools than anticipated. I'll get some photos of it soon.

The 9.5" 14-Bolt Saginaw axle mod is well underway now. I ordered new rear brakes for it, parking brake shoes and some other parts which include GM seal and bearing drivers and some pullers. The brakes were the last GM OE available in the country, as were the AAM 3.73 gears. Going to open and inspect the packages tomorrow for damage. In 2017, the Brake Pad Kit, 171-0999 or 19329677 and Brake Rotors, 177-1149 or 22968231 cost $263.45. Today they cost $386.61, what's that, 68% more in 5 years?

I'll try to take more photos while getting the axle ready. Recovery will slow me down as will transferring tools into the new tool chests but that kinda works in my favor, the weather will start cooling soon. The only tough part is going to be making the truck available for downtime. We have a lot of stuff going on now through the holidays. I do not want one axle gear swapped and the other not for more than a week, thinking about buying a spare front and rebuilding that or swapping it out and rebuilding/regearing the original. I prefer the latter option.

With the need to minimize down time, I might also convert the parking brake system to the JNC "Push to Release" option at a later date. Not too late!

 

[swathdiver]

Picked up an Autool SDT-206 smoke machine finally from a pawn shop selling on Ebay. Finally got it cleaned up and tested and put it to work on the Yukon. Disconnected the passenger side PCV hose going into the air plenum before the throttle body and inserted the smoke at about 3 psi. Held it there for a minute or two and nothing, no leaks. Popped the top of the purge solenoid hose on top of the intake right behind the throttle body and inserted the smoke again, nada. So back to square one looking for the source of those high negative fuel trims at idle.

The tensioner or idler pulley started squeaking for the first time so I put in an order at Rock Auto for new GM OE parts. Not bad for 177K miles I guess. I think the driver's valve cover might be leaking too. The manifold bolt broke on #7 but it isn't leaking yet. A new manifold is only about $100 for that side so I think I'll just replace it instead of fooling around with making the flange flat and replace all the studs, nuts and bolts on both sides, plus the gaskets for the Y-Pipe even though they are only about 60K miles old. What say you?
