Trailblazer

Who in the hell engineered this piece of crap! Or should i say over engineered this thing. Every time i to work on it, all i want to do is punch that s.o.b. right in the nose. Its a 2002. THIS time i have to replace the radiator. I have half the fron end pulled apart and still cant get it out. Looks like there is a plastic bracket that "hooks" under the ac condenser. Unfriggin real. Ford work truck has 4 bolts, 2 trans lines and 2 radiator hoses. Slids right out. I HATE working on this thing!!!!!!!!

Re: Trailblazer

Those vehicles are crap. My neighbor's son has one and it is always having issues. The engines are garbage and the build quality is a joke.

Re: Trailblazer

We had a 2012 we bought new and had no problems with it at all. It was a V-6.

You mean v8? I don't recall trailblazers ever coming with v6s. I5 and I6 engines yes, then the 5.3L made its way in there.

Yes, trailblazers are .............well I wouldn’t own one but I work on all makes every day and I would work on and own a GM long before anything else. Last night an 08 3.5 ford showed up with the water pump shot, 11 hours labor and it filled the crank case with coolant, junk. Try to find a TIPM for any newer Ram, can’t get them and there are only two kinds, those that have failed and the ones are about to. Lift to hood on any Duramax and any Powerstroke and tell me what one you want to work on. We do all of Fed-Ex up here and are forever putting front end parts on the F-250’s. All the manufacturers have built junk over time but when the Chargers loose wheel speed sensors and that puts the trans into limp one really starts to look at who’s building what. And yes, the GM 3.6 with the 6T70 trans will eventually cost every owner a ton of money unless the stars are lined up just for you! 😁

My condolences to you sir. I had to work on those POS trucks when I was at Chevy and GMC and they do suck. Many a time the zone rep and field engineers got an earful from me on that junk.

I have found that to remove the fan clutch assembly, you need to remove the radiator first. If you need to remove the radiator, you need to remove the fan clutch first. Nice piece of engineering. Job justification maybe??

The fan clutch comes off with the fan with the clutch removal tools. Available at Autozone for free rental.

You know you may be right I was thinking of the 2012 Equinox we owned but we did have a Trailblazer too and both my wife and me thought it was one of the nicest SUV's we owned. Never had any problems with that either and to tell you the truth I don't remember what motor that had in it but it definitely wasn't a I5.

Re: Trailblazer

Yeah, the GMT360 trucks are a bitch. My 2003 Ascender has the 5.3.

The fan, fan shroud and radiator are impossible to dismantle.

Changing the rack? Good luck!

Need a starter? Remove a section of chassis and then you can ALMOST see the starter. Of course, the starter covers the crank sensor.

Front diff is bolted TO the oil pan, one shaft goes through the pan.

Mine needed an oil pump. Yep, I did it without dropping the pan. I stripped the front of the truck down enough that my face was an inch from the pan. And I installed the second bolt on the pump tube flange because I ain't doing that job again.

This truck has the original engine & rear, the trans was replaced. It's pushing 360,000 miles. Chassis rot? Sure, I'll weld some plates on it but I'm keeping it!

When a powerstroke needs .........almost anything! 😄😄 In our neck of the woods the trailblazers are forever needing power steering and trans lines. Most people smoke the 3-4 clutches before they notice all the trans fluid running out.

Re: Trailblazer

Im going on 52 ,30 plus years ,and cant wait for my career in this joke of a industry to be over..Every updated model is getting worst to work on and they are still trying to reinvent the wheel.There is a huge shortage of techs everywhere cause young people have smartened up ,young people in the trade leave the first chance they get,the ones that stay can blame it on all the fumes they breath in.My rant for the day ,cheers.

Had to do the exact same thing on my wife's 2006 Envoy Denali! Lots of fun!

Re: Trailblazer

Left the stealership life in 2014. It's all about them making money and not YOU!. I don't miss it one bit. I don't even work on anybody cars or trucks anymore, just do some performance stuff for guys these days as that's what I enjoy doing now.

Was your 2012 Equinox a 4 cyl? If so did it use oil. Ours did, about 3k to a quart (odo read 69k). Sold it this week though.
