Timely Brake pad replacement a must.New rotors at 100000. (A DIY issue for the rears but it can be done). Chaining Transmission Fluid and 4x4 Transaxle & front axle Fluid a must.(Change it early, say every 80000). Quality 5w30 syn oil ONLY for the 4.2. Change the oil & Filter every 3 to 4 months or around 3000 miles to give engine long life.(Don't leave the old dirty oil in for a long time, that causes wear.) Firestone Advantage 2 tires are the best tires for this suv at 33 psi. Keep your headlamps cleaned with non abrasive cleaner and put a dab of wax on them and polish. Put in cabin filters even though factory did not. It has a spot for them. The radiator fan clutch and while your at it belt should be changed at 150000. New battery every 3 years. Top off a/c charge every spring. The a/c on these runs COLD. "Perfect". Dexcool radiator fluid every 2 1/2 years. KEEP the undercarriage washed off, even in summer and especially in winter from road salt. Use a fuel cleaning additive every 3rd tankfull. Suggest the leading brand and it will keep the injectors clean. (Replace that air filter every 50000 with fuel filter at 75000 and Spark Plugs around 125000 with top ac brand. This is the best SUV gm ever built and it is on a Frame and not a uni body. The exhaust from catalytic converter back should last about 200000 if you keep it clean. (That is the only NON DIY Replacement parts job). The 4.2 mileage in city will stay around 13-14.5 and straight hwy only pops up to 19-20 mpg. Engine has enough power with the 3.42 axle. Sturdy as a hd truck and comfort as a full size sedan. Replace the back shocks at 175000 and make sure front and rear sway bar links are changed (total of 4) That is a tough job but someone has to do it.... No need for dealer service if your a DIY. Keep the factory wheels clean all year around. (by the way, lube spare tire crank area every year and test it.Buy weather floor mats in the winter. Use winter wiper blades front and the one on the rear The only issue after all these years is the drivers seat should have been more comfortable for extended HWY travel. (Some of the mileage timelines above may seem early but it will make the Trailblazer feel like factory new all the time, that choice is yours, do it early or follow GM time table.

2003 Trailblazer ls 4wd is one of the best ones Chevrolet built. Heavy duty. Easy Service. A DIY will find it a pleasure to maintain. The divers seat is not as comfortable as it could have been. That is the only thing I found at a slight fault. Lots of power very cold AC Fantastic radio. Summer City mpg between 13-13.5 with 3.42 axle. Highway mpg is 18.4 to 19. Winter city lowered to 11 to 11.5 in just city cold winter driving. Why? Not a clue.****Found low mileage issue. One rear inner brake pad was stuck on rear rotor all the time because floating caliper bracket pin was frozen due to rust. Thus half the pad was always pushing on rotor. Replaced "trashed worn out rotor" and caliper bracket and new pins added high temp caliper grease on new pins. Mileage went right up to 14 + mpg. The caliper bracket and rotor are VERY difficult to replace for a DIY. There was no problem with caliper. Still the same one. I should have known there was an issue like that because the left rear was pulsating every time you put the brakes on. Normal driving without foot on brake, there was no pulsating. Used new oem ceramic pads. Had that new SUV feel again.

2003 Chevy Traiblazer

Family bought the 03 EXT LT 4.2 I6 model in 2003 with 30,000 miles on it. We now have 145,000 miles on it. While this thing has very little steering feel and is slow to respond, it rides fantastic, even on fairly rough dirt roads we use to get to Grandma's house. It also tows well (5000 pound boat), though if you do tow a lot, get the V8. While the I6 is fairly powerful, you do have to rev it past 3000 to get more immediate response. Since this is the EXT model, it has more weight than the base model, so mileage is a 16/20 city/highway. It has gotten us everywhere reliability with basic maintenance. 3rd tow will take adults surprisingly well. We believe we can get another 150,000+ out of her

I still love this car! We live in North Idaho and our winters can throw at us great deal of ice and snow. This car has never let me down. I use a good, siped, all season tire and it just goes. I can't say enough. The only add-ons I have done is an after market stereo and remote starter. I have had not had any mechanical issues only regular maintenance; brakes etc. I wish Chevy still made these.
