I was hoping for this to be in chart form - easier on the eyes than a lot of words, but can't find hardly anything online.

I have a 2003 Blazer 4WD automatic that has almost 119K miles and I'd to keep it running for several more years. I also live in the Washington, DC area and drive during the week in stop-and-go traffic.

The oil is changed regularly - every 3-5 months depending on conditions.

My concern is the major repairs on the horizon that I should be planning for - like the timing chain.

Anyone have a handy chart to pass along? Or - if you have details, I could put it in chart form and share!

 

Can you provide your Engine Size , Fuel Injection Type ?
What was the condition of the vehicle when you purchased it ?
Did you put all the 119 K miles on it ?

 

I don't think you have to worry about the timing chain. That is one area these trucks have zero problems with. I've got 256k on my stock chain.

Your best bet would be to google "2003 chevy blazer owners manual".

It would contain the recomended service interals you are looking for.

 

there is a chart in the manual that comes with your vehicle take a look at that

 

I'd be more concerned with upcoming maintenance concerning :
(1) Fuel Injection - MPI spider or other
(2) Fuel Pump replacement
(3) Lower Intake Manifold Gasket
(4) Trans
(5) Regular Maintenance - Brakes , Fluid Changes
(6) Suspension
