Chevy trailblazer Radiator replacement.

This procedure is the same for most GM vehicles with the 4.2 inline 6 cylinder engines.

Good video. I am in the process of replacing my radiator water pump and fanl clutch, I unbolted the fan blade so that the need to cut into fan shroud was not needed.
The video shows exactly what you got to do, I went through all the steps like a pro.
Thank you.
Much respect 🙏

For the life of me, I couldn't get that damn fan clutch off the pump on my 2003 Trailblazer 4x4 LTZ. So I saw someone remove the front fascia and the upper frame (small part on top of the radiator) . So I did that, plus I removed the the lower frame (frame underneath radiator). With those two extra parte and a few extra bolts that are were easy to remove, I lifted the condenser just a bit to remove it from the bottom of the radiator, then I un bolted the fan shroud from the radiator and I was able to get this thing out!

Great video, I wish I would have seen it before I did the job and left the fan and shroud in. Your way is better.

His cracked exactly where mine did, I am having a problem getting the transmission cooler and getting it to disconnect where it's connected on the bottom left and right, I'am trying to get it to separate with out breaking them.

How come my fan didnt magically dissapear too?

Wait wait, did I miss something? No bolts or hidden "anything" holding bottom of radiator in place? If so, this is going to be easier than I thought. Much easier than an impala, I hope.

Mine cracked in the exact same place on 2004 TB

What fluids did you lose, and how much of it?

Just brushed over the process of loosening the fan blade

español: en la base del radiador hay unas válvulas que por allí se puede vacíar mas fácil, en lugar de retirar la manguera gruesa, después el protector de la hélice, la hélice y el fan clutch salen los tres al mismo tiempo, pero debe primero desenroscar el fan clutch, así sale mas fácil, sin estar dañando ninguna pieza

How did you remove the fan? I honestly missed that part ? Lol

Trailblazer is ridiculous to work on, like why the hell did they design those things to be harder to repair? 🤦‍♂️
