I'm a new (to me) Blazer owner, a 1998 4-door LS. She is rough, but straight with no rust or major damage. In total, all the little fix-its that she will require would be a huge deal breaker for many, and many would consider the little blazer to be a total loss... But there was a little spark in the ride that made me think, "I can fix this..." Not many in my circle would stand back and look at the vehicle as a whole, and say yeah, she could be all that and so much more. Funny, the car has only run twice for me; once to get her home, and a second time to move it where she sits now, next to my tool shop. As bad as she ran, I only pulled two codes: P0102-99 & P0300-B9. Probably two of the worst codes to get, so I have my work cut out for me.

So I gave too much for the Blazer initially, and have already dropped another grand on her from both Rock Auto and Oreilly's. Just the basics: Radiator, plugs, wires, fuel, air and oil filter, door pin rebuild kits etc etc. I picked up both a Hanes and a Chilton, before realizing they are the same manuals...

With 179,000 miles on her, the former owner(s) did little if any maintenance. From this point forward, I have drawn a line on the calendar, and aim to replace every maintainable item, so I can keep a coherent maintenance schedule for myself. I would love to get another 179,000 out of the vehicle.

Any way, off to the technical threads for research, just writing to say hi, and that I am glad to here!

 

Welcome to the forum. I hope that we can help you find the information needed to get your truck running well and it will be an enjoyable ride for you.

 

This is the place to get help to keep your Blazer on the road.

Look for the thread with the common problems and issues as a good start.

Of the possible issues, one sticks out as a possibly causing a catastrophic failure: the lower intake manifold (LIM) gaskets failing and dumping coolant into the lifter valley.

The late 90s 4.3s had this issue. There are reaary good writeups on the forum.
