1990 Gauges Upgrade?


Recommended Posts

Posted

You could always buy the inlays that go over the face. Of course you will need to tear into your dash and pull the plastic face off. I have not done this on a GM, but helped my son on a few of his hot-rod ricers...

Is there another year of gauges that I could upgrade to, better looking or a regular gauge face??

 

I have read about this on another chevy truck forum ... and in order to get a different set of gauges into your truck you are looking at replacing the entire dash ... and you are looking at a lot of trouble to hack and splice into wiring harnesses to try to make the conversion work... it's been done, but not without lots of grief...

I realize a 95+ cluster would't fit into a pre 95 truck. But I've often thought about putting a 94 gauge cluster into my 89. Its a much nicer looking package. I'd have to hook up the tach but would this not fit in without altering the whole dash?

Mr. Tim, don't hold me to this, but I'm fairly certain that you can swap the cluster up to a 1995 into your truck?

 

I say this, but it would REALLY help to see the rear of your existing cluster. I swapped out the instrument cluster in my 1992 Silverado just a couple years after I got it simply because I wanted a TACH and mine didn't come with one. I never could figure out why mine didn't have one and just thought it looked better in a customised truck. Naturally, I wanted it to go faster too and EVERYBODY knows a TACH does that. LOL!

 

Now, I already had the next year style 'needle' gauges from the ones you have (the sweeping arch type, right?) and mine was a VERY simple plug and play. The TACH worked perfectly even though I didn't have one originally and the only thing I did was change out the odometer from my original cluster to the new one with the TACH, so that my miles wouldn't be off. Simple matter of a couple screws holding it in.

My '91 has the disks instead of needles and that cluster has a different plug on the back than the needle type, The tripometer reset is located in a different place and is round instead of square too.

 

That said, I replaced my dash board and used the cluster that was in the replacement dash. While everything worked fine there was one problem that showed up and it was that the odd right front turn signal and side marker would be on all the time. I put my old cluster back in and no more problem. Could be a defect in the replacement cluster but can't say for sure, just be aware that swapping parts from truck to truck or year to year is no guarantee even if they look nearly identical.

Any 91 tach dash will work. The needle guages debuted in 1991 but had the same plug in the rear as the old moonies did. 92-94 uses a DRAC and has a different dash connector. The swap involves moving 3 wires in your harness and adding the tach reference wire.

Check that out. Or....

That is more work but gives you the more common 92-94 cluster.

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

    • 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. 
    • "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...
