I hope this message finds you well! Guys, I have a Blazer 98 with the famous 4.3V6 with 4l60e gearbox. It's a car that I only use on weekends, the moment has come when I want to check, change and do the proper maintenance on the whole car. I wanted to hear from you, experienced what I should do, the most important thing for you to wait a little longer. Of the entire mechanical assembly as well as suspension, brakes and everything! Could you help me?! Thank you in advance!

 

I created a spread sheet to keep track of when I did and needed to do the regular maintenance. I based it on the recommendations in the owners manual.

Have you replaced the lower intake manifold gaskets? These on the late 90s 4.3L were notorious for leaking catastrophically into the lifter valley and allowing the coolant to mix with the oil and get pumped throughout the engine ruining it in less than a minute. As soon as I learned of this, I replaced mine since I am too cheap to buy a 4Runner. LOL

 

I've already had this problem in mine!! I thought it was a problem with the engine seal. (Which I also had to change) in the cooling part I need to pay attention to the hoses, they have rust inside! Could you tell me which spreadsheet you have? Thank you for the answer!!

 

Regarding the spreadsheet, I had to make it from scratch.

Perhaps there are ones you can download from online that you can customize.
