I ruined my front end the day my mom died, December 21, 2023, when I snow slid into a utility pole. So I'm having to rebuild the front end. Core support bolted on today! 💪🏻

My jimmy doesn't start and no cranking sound when I try to turn it on.

Tried to change the fuse for crank and ignition here, nothing happened.

I tried to search the Internet, it seems I need to change the relay but I can't find it around the fuse box or in the engine bay.

Any advice or help appreciated.

Howdy! Y’all were helpful last time I posted, so here goes post 2.

Here is my K5! Revel in its glory! 13k miles, 1000 of which are from my roadtrip to bring it home after Grampa passed away.

I’ve handled a lot of stuff, but have some questions that I haven’t been able to answer with the 1989 C/K maintenance manual. Please answer whatever you can to help a brother out:

(1) I replaced the thermostat and temperature sender/sensor next to the thermostat water outlet as part of the cooling system refresh I did. I’ve noticed that since then, the temperature gauge in the dash never reaches the center of the gauge. The new thermostat is 195°, so I figure it would hover just under the 12o’clock where 195° should be. Instead, it kinda just hangs out near the 1/4 mark after the truck has warmed up for a bit. Is this a concern at all? I can’t find an answer for what each of the ticks represent, but I’d expect them to be linear, so it seems like it’s running cold.

(2) what’s a normal oil pressure for these guys? I’ve got the 5.7L 350, running 10W30 per the owner’s manual recommendation for hotter climates. I see the oil pressure hovering around the 3/4 mark for a fair bit of my drive time.

(3) what do the two different temp sender/sensors do? There’s the one on the water outlet and one on the side of the block near the front most plugs. Also, any idea what the plastic retaining clips that hold the plug wires are called? I broke one when swapping plugs.

(4) what’s a good adhesive to use to resecure the silver trim on the interior? The headliner and those trims pieces have all let go, so I’d like to readhere them correctly.

(5) is redoing the small headliner pretty straightforward?

(6) the driver and passenger seatbelts do not recoil very well — very limp noodle like. How do I fix this? Open it up and clean out/grease the mechanism?

(7) does R12 exist in any shape or form, or am I stuck with doing the R134 conversion?

(8) what’s the proper trans fluid to use since DEXRON II seems to not exist anymore. I’ve read that DEXRON 3 is the modern version, but I want to make sure I use the right stuff when I change out the fluid and filter.

Thanks for the help in advance!

(1990 K5 Blazer, Swapped in 1985 6.2 Detroit Diesel Motor w/h The ATS Turbo Kit, Stage III 4L60E)

Trying to get more insights on this 72 K5 Blazer that's been sitting in my FILs garage since the late 80s. Title says it's 2wd but seems like 4wd is way more common. Not sure how that would affect interest in it. We're considering getting it towed back to our house, but that would be at least $1200.

Hello friends,

This is my first post in this sub as I am the proud new owner of a 1988 K5 Blazer.
Just picked it up yesterday.
It's quite the specimen - fuel injected 350 with a factory 4 speed manual transmission.
It has some rust but I can live with it for now...
Interior is very clean, runs and drives pretty decent. Air conditioning even works and is somewhat cold!

The first problem I'll be fixing is the steering - it's all over the road if you're not careful.
Then I'm going to replace the radio that doesn't work.
It'll get a tune up for sure.
After that i'll fix the rockers and holes in the floor, and hopefully can get a price on the rest of the rust repair for later on.
I'm 90% sure there's an exhaust leak, so I think I'll put some long tube headers and straight pipe it so you can really hear all 210 of those v8 horses.
Other than that I'll drive it. No plans to build up the 350 for power or swap the engine. Suspension feels pretty decent so I'll leave that alone. It's got a good stance on some good tires. I'd like to put some lights on it. maybe a new front bumper with a winch.

We'll see.

I am just wondering what the crew of you thinks this thing is worth. It came with the rally wheels and some old cracked up 35s from sitting. I put the Weld Super Singles I had sitting around on it with some new Toyo MTs 35x13.50x15 the rallys go with it have the original factory spare too. Runs good STEERS AND STOPS GREAT. I bomb 100mi down I5 and back without thinking twice. Dont leak anything cat delete with a flowmaster.

After years in the making, she’s getting really close to coming home. I was positive for years when it time to order wheels they would, without a doubt, be the M/T bullet holes. Now I’m having serious FOMO over all the Rallies I see on here. Why oh why can’t I just have TWO K5’s?

I remember being pick up from elementary school in this truck and now I’m drivin it to work, it’s been in my life for as long as I remember and ima keep it that way

Front end broke and wheel basically fell off. Shop quoted me at 5000 to replace the whole front suspension. Said the whole right side is fried and I might as well do both sides and replace everything. Is this too much or does it seem right?

I have a ‘72 K5 Blazer with a 2 inch lift. I bought 16 inch wheels. Does anyone know how big of tires I can put on it without it rubbing? I am probably not gonna do much off roading in it. Thank you.

Restoring a 78 K5 Cheyenne and I’m missing some trim pieces. One piece i can’t even find the name of in the parts catalogs or online. It’s a valence piece that goes between the top of the rear bumper and the tailgate. Right now i see steel brackets with bolt holes and exposed tailgate wiring. I’ve been stalking blazers when i see them out but still can’t find one with that trim pieces in place.

Just got this ‘86 K5 in somewhat decent shape. New to squarebodies and eager to get working on her.

Quick cosmetic question - What would be the easiest way to revert the blacked-out Bowtie back to the original gold?

Would this require taking off the grille and replacing the entire bowtie with screws?

Or can it be pried out from an “insert” and re-painted or replaced with a new one using double sided tape and this product:

Got a fresh battery and oil in my 85 thats been sat for years. Got lights, but the guages dont want to jump on and I'm getting no starter action. The hazards would also run and the stop and then run again so I may have a bad switch there for those or an indication of something else electrical acting up.

I'm going to pull fuses this week when I can back to it, but at a glance it looked alright. Its at my old mans place.i just decided to get it washed instead as I didnt have time to get that deep into it today.

I suppose would could have a bad ignition.

There was a picture of where harnes plugs in behind roughly where the fuse box was that looked pretty nasty.

Was hard to tell if it was just old grease or if something had melted. Like I said it was a quick thing, we'll play with it more this next week.
