I used to have a 1992 S10 with the 4.3L V6, and I experienced some serious overheating issues. Make sure your cooling system is in good shape! A new thermostat might help.

3

I’ve heard others mention that too! Did you ever get it fixed, or did you just sell it?

4

I’ve got a 1992 S10 as well, and let me tell you, oil leaks are a frequent problem. Check your valve cover gaskets; they often wear out and need replacing.

5

That’s so true! I noticed mine leaking, and it was just the simplest fix once I figured it out.

6

Performance issues can stem from a lot of things. Sometimes, it’s just the fuel filter! Keep an eye on it, and replace it if it’s clogged.

7

Good point! Cleaning the fuel injectors can also do wonders for performance.

Honestly, I love my S10, but it can be a bit finicky. I’ve had to replace the ignition module twice! Just keep an eye on your electrical systems.

I hope you all realize these issues just add character to the truck! It’s like having a pet—sometimes you just gotta deal with their quirks.

11

I like your way of thinking! Helped me to laugh rather than cry over my truck’s problems!

12

I’m curious, what kind of mileage are you guys getting with your S10s? I feel like mine has taken a hit recently.

13

Mine averages about 15 mpg, but it has the original engine, so I suspect that’s part of it.

14

Keep an eye on your spark plugs too! If they’re worn out, they can cause misfires that affect overall performance.

That’s something I totally overlooked! I’ll check them out this weekend.

I love the S10 but wish it had more power sometimes! It’s a bit like a turtle on a race track with the hills around here.

Hey! The 4.3L V6 has great potential for mods. Start by looking into a good performance chip. It can optimize fuel maps and give you a noticeable boost in power.

19

That’s solid advice! I’ve heard that adding a cold air intake can also improve airflow significantly. Anyone have experience with specific brands?

20

Absolutely! A quality cold air intake paired with a cat-back exhaust can really enhance performance. I recommend checking out K&N filters for intake upgrades.
