ORVietVet 2004 Silverado K2500HD Crew Cab 6.0

[ORVietVet]

On April 9, my shop owner friend, who is the son of the man I bought this truck from, has scheduled me in with the truck to do the oil cooler and transmission cooler lines, the transmission service and replace the solenoids/switches and harnesses and to do the lower steering column bearing. He said he had meant to do all of this work himself, except the transmission solenoids/switches/harnesses, but shop work got in the way and he kept putting his father off. I have all new Genuine GM parts and he said as long as I help, which I will, the shop use fee will be minimal and also allow for military discount. I have very slight seepage at one of the hydro-boost lines and if I can get it here by then, I am gonna add that in too. There will be pics.

Ok, gonna end up doing the "seeping now but sure to leak more later" hydro-boost unit. Looked and could not find a new Genuine GM or new AC Delco unit that listed the correct GVWR. The one I did find is from Bosch who makes several OE manufacturer units and I believe they make them for GM but not 100% sure. Maybe someone here knows.

According to GM Parts Direct, when I look at the OE part # and look at RA, the Bosch crossover for the correct GVWR is 0204777573 for $224.03 at RA, shipped and includes the 5% $10.95 discount. IIRC, all GM ABS units are Bosch, again, I could be wrong.

This morning, I pressure washed the booster/master cylinder area and the lines to the p/s pump assembly and the p/s pump as well. Took it on a long drive that was made longer because I wanted to put miles on in town with more brake applications and steering involved. Gonna be checking the entire system between now and April 9.

The new Bosch hydro-boost arrived today from RA. I have decided to also do the brake pedal pivot bushing and brake light switch while I am doing that hydro-boost replacement. Those parts are ordered from RA and on the way. So, now all in one day, oil cooler lines, transmission cooler lines, transmission service and solenoids/harnesses replacement, lower steering column bearing replacement, new hydro-boost, brake pedal pivot bushing and stop light switch. Between me and my friend, should be doable. Gonna start at 9 am and hope to be done by 6 pm.

 

[ORVietVet]

I had not yet ordered the brake pedal bushing or the brake light switch. They came yesterday. talked to my shop owner friend yesterday and we are good to go. The whole day will be just us two on that truck. I gotta buy lunch too.

 

[DateNight]

your a machine!

 

[ORVietVet]

I could do it all at home by myself but having a whole day at the shop with a lift, is too hard to pass up. Doing the cooler lines are doable but all that time on my back would wear me out. At 72, I need to admit my limitations.

This is on my 2005 Tahoe Z71. Came back from tacos today and coming down my street and my landlord pointed at the d/s front and said my daytime running light was out. Sure enough, it was. Opened it up and the bulb/socket were both charred and slightly melted on one contact. Had to settle for a Dorman part and I replaced old with new and a new bulb and now, all good.

 

[ORVietVet]

If you look close enough, you can see the socket got hot enough, that it is no longer round.

 

[1997]

mine looked almost as bad, was able to salvage the sockets, replaced bulbs with LED's.
i'm surprised there hasn't been a fire related to them.
most of the GMT800's i see have 1 or both of those lights out.

 

[ORVietVet]

On the Tahoe/Yukon Forum I belong to, same forum owners as here, I was told I should put LED's in mine. BUT, I consistently see problems after members doing that. Strange lighting problems.

 

[1997]

thx for the heads up, keep you posted.
GMT800's seem to have "strange lighting problems" from the get go.
not a fan of their auto lights and that sensor in the middle of the dash etc.

 

[ORVietVet]

I have been lucky with just 2 bulbs in 5 years on my 2005 Tahoe Z71.

Strange lighting problems? How so?

The little sensor on the dash is just a "dusk-to-dawn"-type sensor. You can override it. The 99-02 is unique, in that you have to cycle the dome override push button twice, and you get a chime to tell you...oh, I guess that's the DLR I'm thinking about. NVM...

Yeah, those DLR sockets do get damaged from the heat over many years of use. I just changed one I had laying around. Can't remember where I bought it but it was an AC Delco one. Maybe going LED on those will solve the issues?

Front headlights tool-less removal is the best GM has ever produced afaik. We need to find the fellow that designed that system with the little rods and congratulate him! It's friggin' genius!

No removing bumper or whatever on the newer generations. And the rear tail lights are great as well. Nothing like that goofy taillight circuit boards like on the previous generation: what a horrible design.

Hell, on the newer ones, you cannot even replace the bulbs. Has to be whole assembly. Did not pay that close attention as to problem descriptions but lights flickering. Lights only working on one side....etc. All just after replacing bulbs only.

When I had my 2014, I had one turn signal bulb go out. Took me 5 hours of finagling it just to get the damn headlight out. That and a long list of other issues is why I no longer own it

I've had Sealight LEDs in my 03 Yukon for 3 years now, not a single issue (knock on wood).

I did look at a 2012 Tahoe, long ago before I bought my 2002 LT Tahoe and then my 2005 Tahoe Z71, because it was a 1 owner and supposedly well taken care of and a good price. The inside of the coolant reservoir bottle was deep rust color. Rust all over the frame. Right then I know it was not an Oregon vehicle. we do not use salt on roads. It was just waiting to cause a new owner problems.

I love the GMT800 platform. Way less problem prone than other series.

There were some owners that had no problems at all and those may have been on a different series. I did not pay attention to whether GMT400, GMT800, GMT900 or newer series that were prone to problems as a changeover or the new design in there newer trucks. I am just set in my ways.

can't turn headlights off, my switch is pictured, you can move it to the O position, but it snaps back to A. in A lights come on/off randomly with changing brightness etc. Also headlights come on when you start it up anytime for some reason, then go out pending outside brightness.

unless i'm missing something?



agreed the headlights with those rods are a great design.

Understand.

Oh, that's strange. Unless it's a Canadian thing (that's where I recall you live, right?), switching to the circle should override and turn them off. That's basically the OFF switch.

Headlights being ON on startup I think is normal?

But them coming on/off with varying degrees of brightness sounds almost like grounding issue. That's definitely NOT normal.
