Hello,

I just thought I would say hello since I found this forum. I just picked up a 1995 GMC Sierra Ext Cab Z71 with the 350...

 

Anything I should look out for? I was told cab corners are known to rust out... The frame is a little rusty, and I had a rear brake line blow on me Saturday but lucky for me GM designed the fluid reservoir to section off rear and front and the failure was in the rear... I fixed that issue...

 

My plan is to replace the following:

Trans fluid and filter (Auto)

oil and filter

O2 sensor (what should I get? Denso?)

plugs and wires

fuel filter

air filter

 

Anything else I should do? The engine has 129k on it... I have never swapped out gear oil from a diff. Anything on here about doing that? Also, I am not sure if I have posi or not yet... If I don't where can I get it from? (Looking for best cost to quality ratio)

Welcome to the forum,

 

Everything you've listed sounds good so far but since it's a 4x4 i'd also replace the fluid in the transfer case aswell make sure you TAKE THE FILL PLUG OUT FIRST cuase you don't want to get it all out then not be able to put any back in, It probably wouldn't hurt to do the diffs and those are simple and the same rule applys for those as the transfer case. I'd personally probably go with Delco 02 sensors and if the frame is rusty spray some rubberized undercoating or rustoleum rust protection spray paint.

I was thinking about pulling the bed off this summer and sand blasting it and fixing the dings and repainting it... So while I did that I was going to sand blast the exposed part of the frame and then paint is with rustoleum... The truck is sitting in my garage so it shouldn't build much more rust from now until then...

One of the first things I do with a used car is to get an alignment.

 

$0.02

 

I was thinking about that myself... I am getting a new set of tires. (any suggestions would be greatly appreciated.) So I was going to get it aligned. I also found out today that my thermostat is stuck open as the truck never fully heats up. I need to add that to my list of things to get. While I am in there I will flush out the green stuff and put new, yellow, high-mileage stuff in... I will also do a can of sea foam before I change the plugs, O2, and oil... Just so I know those CC's are nice and clean.

 

So tires... I was thinking about getting: On/Off Road Destination A/T's

I always replace the shocks on used 4WDs. Sometimes I change the steering stabilizer too.

      I like the idea.  I would pick diesel if I had a choice. I need pictures though.

      Help purchasing a touch screen digitizer

      By newdude · Posted

      I've installed cheap eBay new aftermarket digitizers before.  They work.  Did a bunch of Cadillac CUE (aka Cadillac's MyLink) for someone years ago.  They all worked fine after the repair.    That number 22740886, that is a component part # for GM.  You can use it to search, but its not something that's obtainable at the dealer level.     So pretty much any of these will work - 2015 Colorado Digitizer for sale | eBay

      Exhaust heat while towing!

      By fondupot · Posted

      You can install tailpipes that direct the exhaust sideways vs the OEM one that goes straight back. There are several on the market, do you own research. HOWEVER, you need to make sure the Venturi vents are still intact, otherwise it will throw a engine code. There is a sensor somewhere that detects back pressure on the exhaust. And if it doesn't collect the correct metrics, it will throw the truck into limp mode.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      "Teardown" is complete. Head surfaces are clean and ready, new intake is prepped and ready. Coolant drained and water pump is removed, radiator is removed, new hoses and pump are ready.   The replacement intake is also from a '95 (with I think 260k, the odometer said). Noticeably less pitting where it covers the rear coolant passages. I'm not sure if that's a tribute to more frequent use, more frequent coolant changes/upkeep, or if the intake was machined at some point. But it appears I found a good one.   My coolant hoses were original, and the lower hose still retained the factory spring inside. It's not really rusty, but it's got deposits all over it. Unsure if I should re-install it (will thoroughly clean it first). Someone said hose technology has gotten better since 1995 (has it?) and I don't need the spring. I think modern EPDM is what made those hoses last from 1995-2026, so it's a question of how much suction can the water pump really pull, and will it collapse the hose without a spring?   I'm stopped and waiting for parts, however.   When I first brought the truck home, the fan was intermittently hitting the radiator shroud. I could see someone had monkeyed with the shroud (put a bunch of cardboard as a spacer between the upper/lower shroud halves. Someone said the motor mounts have likely failed and the engine has sagged. I wasn't sure I believed that. The engine is really solid in its mounts: To remove the old intake I *just* nearly permanently welded to the heads with freshly cured RTV and gasket snot two weeks ago, I literally had to use the arms on my lift and a chain with a bolt attached to the intake to pull it loose. It almost picked the front of the truck off the ground before ....scuuuuuuuuuuup.... I could actually hear the gaskets tearing and it broke loose and the whole truck settled back down. Motor barely moved.   SO, those parts I'm waiting on... The lower radiator mounts/bushings had completely failed. The radiator needs to be insulated from the rad support, and the bushings help the rad stand at the correct height. The plastic "baffle" was also destroyed at some point. Someone had attached the shroud to it incorrectly, overlapping a joint that should have been underlapped, creating another suspect issue potentially causing things to hit the fan. Broken tabs, side is busted off, and it's perma-formed/bent where it was jimmied incorrectly.   The baffle? Unobtainum. Long since discontinued from GM, of course. Aftermarket/capa/chinese? Also unobtanium. In GM's infinite wisdom, it appears there are at least two different variations whether the Blazer is 2 or 4 door, and I can't yet tell if they shared the same part with the S-pickups. Plan B, if I can't find a viable used one, will be to create a bracket to re-assemble the critical joint I need to seal a gap with the shroud. But that will bug me, it won't be...perfect.   The water pump bolts appear to have been installed with...plumber's putty. I guess, sure, if it works...? I've found a few "backyard fixes" like that. Someone's been here before....   If I can't find someone to jam bamboo under my fingernails to fill my free time this week I think I'll install the driver's power window motor and replace the rear door speaker that's inop. I've got a genuine GM "9.5" ohm working replacement. Why GM used a non-standard resistance....nevermind. Of course they did, you can get more sound from a cheap factory amp that way.   And the saga goes on...
