2005 1500 5.3L 166k miles on it. Have had it since 70k. Done the normal oil changes. Changed all fluids in coolant, front and rear differentials and Transfer case. Replaced spark plugs and wires at 100k. What else should I have done? AC system has not been serviced or fuel system. Should I have that stuff done?

Don't touch the AC system, if it works good don't mess with it.

 

Do brake fluid flush and replace the rubber hoses if original. That is a lot of miles and years on those rubber hoses.

 

There are tons of other things you can do but that is up to your wallet. Like you could go around and replace all the bushings in the controls arms or replace all the parts but that gets expensive quickly. Shocks could be done if original.

 

The fuel system you can't do anything with. There is no fuel filter to change, it's internal on the pump.

normal wear items that will start failing, include undercarriage items such as wheel bearings,  cv axles, u- joints,  brakes, rotors, ball joints and shocks.

Engine components such as both drive belts, alternator,  belt tensioners, water pump, thermostat, both top and bottom hoses, and the hoses that plug into your hvac system. 

 

So there are a lot of items Ive listed that will no doubt fail, some faster and more likely then others. So if I were you and you have a few grand lying around, I would start purchasing items and put them on your shop shelves.  Start with things that will be needed to get your truck running with little effort, such as the Hvac hoses and allows you to do multiple things at once with the same procedure. When doing the Hvac hoses, install a new water pump, thermostat, top and bottom hoses. At this time inspect your fan clutch as this is another wear item. If it spins freely as if there isnt any resistance go ahead and replace it.

 

I noticed you did a coolant change already, and front dif, rear dif, but didnt see you list your tranny.  This is something that should be serviced as well. A new filter, is a must, and you could go with just changing the pan fluid, or you can do the complete system swap, that does not require a factory flush. There is a great informative write up about how to do that, and its highly recommended. 

 

If you want a great ride and a little more out of your trucks performance, I recommend getting the bilstein 5100 shocks, they are every bit worth the extra coin. Inspect your wheels for play or clicking, changing the wheel bearings and cv joints is really easy and will prevent headaches down the road, do both sides at a time, and be sure to replace your brakes and rotors when doing this project. Also inspect your ball joints at this time. Those are more labor intensive, and If they are in good shape I would wait till they start to fail before attempting this one. 

 

Have the u-joints on hand for your front shaft and rear shaft,  and when you do a oil change with the truck in neutral check for play again wait till they start showing signs of wear before changing them.

 

It really comes down to how much time, money and how big your shop is.

The one thing with this truck is replaced almost everything on it [emoji23]. Brakes lines rusted out. Replaced with copper nickel. Radiator went bad and put coolant in to transmission. Rebuild on transmission. Wheel bearings twice in 90k didn’t think was to bad. Knock sensors. Original alternator. New belts 4 years ago. Axel seals in rear differential. 4x4 encoder motor. There was a ton stuff that went bad.

      Evan Williams Bottled in Bond   So pouring the last of a bottle of Evan Williams Black label last night I set off the the state store for a refill only to be denied the by an empty shelf. Rats.    What the did have was a bottle of Evan Williams Bottled in Bond. 100 proof. Hum, a few bucks more but a known distiller. Lets have a swing at it. ( I have before )    Cracked it open and pour a serving over ice. Hum.... more heat, yes. More alcohol naturally. But the barreling not the proof brings the taste and this one came up short.    Oh is was familiar but the heat ran the barrel over like a Peterbilt runs over a squirrel. Could use a heavier toasting of the oak me thinks or perhaps a longer barreling. Who knows. But what I can say is ice or a water back isn't the answer. What kills one kills them both. Sad. It is a pleasant drink....if you have little to compare it to.

      Bridgestone vs Goodyear tires?

      By Grumpy Bear · Posted

      I've had exactly one set of Bridgestone. Lasted five year and 125,000 miles and had I known better 15oK would have been a cake walk. I would have bought a like set had they not tripled in price since the first set. I removed them at said mileage with 5/32" remaining in dead even wear all four. They were fuel efficient, quite, comfortable and predictable.    Early on I got a very good alignment checked at least once a year, sometimes twice; kept the tires properly inflated, balanced and rotated. And I've found that many a tire issue can be avoided with great maintenance practices. Lot's of tire dealers will do rotation and balance (simple) for free for as long as you own the tire they sold you so no excuse not to.    Bead prep, alloy integrity and stem health have a huge impact on inflation stability. There are more mountings done poorly that perfectly. Finding a good tire guy is gold and as important as finding a tire you like.    That 3X price increase now two sets of "other tires' later is starting look like a bargain.      Bad maintenance kills more tires than bad tires.

      Atlas, you kill me As aggravating as a project like this can be you have been unable to hide your fascination with learning and using that angst against this beast like a Ninjitsu Master. It amuses you, admit it now.      BTW, love your writing style. 😉

      I gotta say, I'm enjoying your narration. The troubles you've been having are amusing as you describe them. It's good to see that you're finally getting some satisfaction out the old beast though.

      Declaring victory would upset the demons that possess this Blazer, so I won't. But I did make progress today--after it put up a fight. Always a fight.   I had the day off so I spent the morning cleaning up the shop and I thought I'd get ahead of things by filling the cooling system in prep for the final part I needed to arrive: the driver's side knock sensor. Glug, glug, glug....and then the unmistakable sound of liquid hitting the shop floor. It induces the same chagrin when the sonar and targeting laser temporarily malfunction during a late night bladder evacuation over the toilet with the bathroom light off. D'OH!!! That made a mess...   Oh, hey, that knock sensor I removed? It threads into a wet port. Who knew?! Learn something new every day. Put a pin in that chore, I'll fill it the rest of the way later.   The knock sensor arrived at about 1pm. I threaded it in, connected the wire, filled up the coolant, checked for leaks, and... drumroll.... fingers crossed for a perfect start, excellent timing, model fuel trims, and ...no squeaks... Here goes.....   No, it didn't start. At all. I cranked it a few times and it wasn't sounding good. Furthermore, I heard leaking again. Jesus H Tapdancing Christ, stop leaking all over the dang floor. This time I had accidentally overfilled the coolant reservoir and the churn of the water pump via cranking caused a bit to burp out. Ok, just, breathe... Put the flamethrower down. Dang thing wouldn't burn anyway, leaks too much...   Did you know the rotation of a round crank sensor in a round hole, matters? I do now. Took me about half hour to retrace steps and realize what I had done. Then it started right up.   No squeaks. The squeak was the old balancer.   Once it entered closed loop, fuel trims are dead on, hovering right around zero at idle. No more -30%. I'll credit the injector rebuild on that one.   Timing? I think there's an OBD 1.5 translation error with my Actron scanner. It's anywhere from -20 to -30 at idle, sometimes as high as -40 cruising. Sorry, the engine just isn't running that smoothly at -40 degrees ignition advance. It's just not. It's smooth all through the rev range and has decent power. I'm going to have to trust the seat of my pants on this one.   The new exhaust is very quiet. The old catalytic converter? Not melted, but definitely not healthy. Rains glitter when you turn it on its end...all the precious metal is flaking out. Once the new exhaust system burned in/smoked off a bit, the engine's exhaust smell is normal again. Not that I'd recommend going around huffing car exhaust, but, you know what I mean?   One problem to correct. The new exhaust has the opposite problem of the old spliced up exhaust. It wants to hit the floor where the old one wanted to rest on the cross member. Happy medium, please? Still noodling on that one, need to look at how I can adjust some hangers.   I don't know what's next. On one hand I want to run away from this thing as far and as fast as I can -- there have been a lot of NOT fun moments. On the other, now that it kinda drives nice, maybe drive it around for a little bit?   Shhh... it's not currently dripping oil all over the floor. I can see just a little wet at the bottom of the timing cover where it meets the oil pan seal. It's not dripping multiple drops with every ignition cycle, in fact, after some driving this evening it has yet to even form a drop that could drip off yet. But the weekend is young... I fully expect this could turn into Exxon Valdez by Sunday. Because this Blazer hates me. LOL.
