1989 K5

I got interested in purchasing something with 4WD after moving to Colorado and falling in love with snowboarding. I've always had an appreciation for older vehicles and loved the idea of buying something that needed work and doing it myself. I was already doing maintenance jobs on my first vehicle (1996 Mitsubishi 3000GT), and was proud of the money I had saved and the knowledge that had come with those experiences.

At first, I was considering a lot of things: Tacoma / 4Runner / Land Cruiser, XJ, even a few vans. Then, I got to talking with my brother in-law. He has a 70-something K5 that has been a project of his for a long, long time. He turned me onto the K5, Bronco, and Ramcharger. Initially I was hesitant to copy him, so I focused on the Bronco and Ramcharger for a while. But as time went on, I couldn't get over the look of the later K5 models. In my humble opinion, they're one of the best looking vehicles ever. Before I knew it I was out chasing down Craigslist ads and driving Blazers all over the Denver metro area. I finally found my truck on a farm outside of town in Elizabeth, CO.

The truck is a mostly stock 1989 (350TBI / 700R4 / NP241) that was worked on by a grandfather and his grandson over the course of 4 years. The idea was that they would work on it together out in the grandfather's barn, and when the time came the grandson would have it as his first vehicle. They rebuilt the engine, patched the floors, put in all new interior, swapped out most of the old fluids, etc. Unfortunately for the grandfather, the grandson's parents were not particularly excited about the K5 being their son's first vehicle. So, the grandfather was selling it and giving the money to the grandson instead. It was a tough conversation to have because the grandfather was clearly sad that their project wouldn't be the kid's first truck. When buying it I did everything I could to ensure him that I'd take great care of it and (hopefully) own it for life.

I am, without a doubt, one of the least experienced members here on CK5. So, most of the updates on this thread will be silly noob questions and run-of-the-mill maintenance updates. Jobs I have tackled pre-build thread are things like greasing zerks, bleeding brake lines, and changing the transmission fluid and filter. In fact, the only add-on that I've installed is an ORD steering box brace. So, you probably get the idea. But, it will be nice to have a trail of history that I can look back on... and it will be...

That's a great story. Makes me sad for the grandpa but I guess there must have been some lack of communication between him and the parents. I hope it pays off for the grandpa in and the long run. Maybe his grandson will find a new project when he's out from under his parents' thumb and they can work on it together.
 
Prior to making this build thread, I took off the camper shell and put on fresh seals from LMC. While the camper was off I sanded down the bed rails and painted them. I put down a layer of primer first and then a couple of layers of basic rusto spray paint. Unfortunately, I didn't get many pics of the process. Looking through my phone I could find only four...




 
Got out there a little bit tonight, and boy did I make a mess of things. Started off by trying to clean up my EGR valve. I hit it with some carb / choke cleaner that I had sitting in the garage. Only after spraying it did I see on the label "NOT RECOMMENDED FOR FUEL INJECTED VEHICLES". Oops. I used it on my Mitsubishi, wish is also EFI... so hopefully that's not too big a deal.


Next, I tried cleaning up the plates that sit between the block and the EGR valve. Man, that was a bad idea. Pieces of the plate flaked off all over the place when I went at it with a wire brush. Probably not my brightest idea.



Then, I thought I would try and get the rest of that air cleaner gasket off. It stuck on like glue, so I had to pick at it piece by piece with my fingernails. Wasn't working too well. I started on it with the wire brush - tried my best to keep dust out of the intake.


After that was the real mess. Some of you might recall that I mentioned having some coolant sitting in my engine grooves in this thread. Well, I tried "reseating" my radiator hose to stop the leak. Of course, coolant came rushing out of the hose once I got it off. And of course, I had forgotten that my air cleaner housing was off. So I got coolant in the intake. Cursed myself for the next hour - such a dumb mistake.


Anyhow, after that I got everything reattached and hosed down the engine bay. My Haynes manual said that coolant should be washed off immediately, so I got after it as soon as I could. Once everything is dry, I'm going to clear the ECM codes by unhooking my battery. Then I'll get behind the wheel and see if the codes come back.

Regarding that coolant in my intake... how screwed am I?
 
The plate you took a pick of the the actual gasket...
 
Might irritate a plug. Once you replace those EGR gaskets, run it
 
LOL man... I was just brushing on the gasket then. No wonder. :ROLFLMAO:
Its ok, we laughed with you

We all start somewhere.


And don't fuss over the carb cleaner, just watch as some of it can eat rubber or paint
The generic stuff from Wally world actually works better. It will strip paint, like the old carb cleaner use to
 
Got back out there tonight and replaced the EGR gasket and the air filter housing gasket too. Took the truck for a drive and everything sounded / felt great. Happy to move on to checking out my u-joints for wear.
 
Wanted to check-in despite not much progress. Figured I'd let you all know I was still alive...
  • Still need to check out my u-joints. Gonna get to that this week hopefully.
  • Got some old shocks from @Justin V. Gonna swap out my old shocks with those.
  • Gotta figure out a solution for my seatbelt. I'm one of those guys that likes to feel it tugging on me at all times. Mine retracts... sometimes.
Pics incoming in the next week or so. Does anybody have a recommendation on aftermarket seatbelts to use? From surfing through old threads, it doesn't look like cleaning my belts will help with retraction because GM designed them to act this way.
 
That's a nice looking blazer. You will have a ton of fun with it. I wanted one really bad when I first got my license but things didn't work out and it took ten years before I bought one then another almost ten years before it was a driveable rig.

I've been pretty lucky with mine. It hasn't given me much trouble at all. There are a couple of trouble codes that are active, but the truck drives just fine. I love it and I love driving it.
 
...Speaking of driving it, I brought it into work today. I've actually been behind the wheel of the Blazer a lot lately. I can't wait to get some time to do the work that I've been promising, lol... work has been brutal lately.

Anyhow, I shot a couple of photos of it in the garage before walking in:

My seatbelt was not quite behaving correctly, I think it was not fully retracting or something. I unbolted the big hex head bolt at the seatbelt retractor housing (lower part) and put in two thick washers between housing and body side. Something to do with the white door button plunger not sitting at the right depth when the door was closed.

Holy cow, thanks for that post. It's worth a shot, especially because my door hinges need to be replaced. The doors don't sit flush as they should.
