Gentlemen,

 

Believe it or not, replacing the oil is not the big issue. Changing the filter is the big deal. Clogged filter means instant burn up as the pump starves for oil and clutch pressures drop.

So you would just change the filter on your engine and leave the oil.

 

Heat brakes down oil...period

 

It takes a lot longer without the byproducts of combustion ingressing into the oil, but it still brakes down.

Also, the friction modifiers and additive pack wears away after time.

 

But do what makes you happy...I've seen vehicles go 200K+ km with out an oil change...of any type...ever. Would I do it...not a chance...but its your truck, so do what you want.

:eek: Drop the pan for sure, You'll see the reason in the bottom of the pan . Dark goop metal fileings, and also clean the little magnet attached to the bottom. Most shops will do a flush/pan drop for more $$$$ ,But do it yourself and save! Also check into adding a drain plug in the pan ,makes for a much cleaner job Good luck!

Good question. I do complete BG Flush on all my vehicles about every 2 years (prob about 20K-25K miles). Prob overkill. Curious to see what everyone else does.

I'd drop pan change filter and then do a full fluid exchange with Dexron VI. Then you would be good to go. Otherwise you would have to go back with Dexron III or if you did go with VI then you would have a mix and not get the full benefit of the new fluid.

Gentlemen,

 

I never said clean oil is not good. I only said that the filter is very important and changing the gallon or so of healthy trans oil is entirely adequate. If the trans oil was rotten looking, I would definitely go further. I suppose i was seconding the concept of pan drop with filter change. Engine oil is a completely different concept and just changing the filter is silly.

 

There is nothing wrong with replacing the trans oil completely, I would do it by the cooler line method rather than some crazy machine I know nothing about. I would definitely replace the filter though.

I know it's overkill, but I had some Transynd sitting on the shelf that I didn't want to go to waste...so I ordered some more and will do a "Hoot" style changeout of all of the fluid sometime before Christmas...and I'm just shy of 100K. I like the idea of getting all of the old fluid out of there, especially since I don't know the truck's full history.

      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...
