Changed water pump in trailblazer blowing out cold air
You need to bleed the air out of the system. Open the radiator cap while the engine is cold. I like to put a rag loosely over the opening to catch any splashes. Start the engine and let it run at idle. After it warms up you will start getting some "burps". Let it go until they stop. Be careful, the fluid will get quite hot. You may need to add a little fluid when it is done.

Where do you put starting fluid at on a 2005 Chevy trailblazer to get it to start
spray it right into the air cleaner only spray it for like 6 seconds. then go try and start the car if no start remove the air clearer and spray right down the air inlet port again only for like 6 sec restart the car if it runs allow it to idle then reff it up past 1000 rpm to get the alt working reinstall the air cleaner.

Trailblazer slow excelleration from 1000 - 3000 rpm.
several things on a 4,2 can cause lazy acceleration,but the most common is a plugged catalytic converter,check up stream and down stream o2 sensor for activity,up stream should be swinging low and high and downstream should be fairly steady if cat is good,if down stream is erratic like up stream reading low to high 7 to 10 or more times a minute,suspect faulty cat. you can buy after market cats cut out the old one and weld in new one,much cheaper.

Will a 05 engine fit a 06 trailblazer 4.2
Hello Mark,
As long as your swapping your 4.2L 6 cylinder SFI DOHC 2 wheel drive with the same block all should be compatible.
Check the blocks casting number to make sure all the correct mounting bosses line up with your blocks motor mounts.
