Question about Injectors
Question about Injectors
How difficult is it to install a set of injectors in the SS/SC? Is this something I should leave to a professional or is it safe to attempt on my own?
It is a pretty easy install. 3 bolts hold on the fuel rail and it pops out. The clips on the injector harness are easy to unplug as well.
-remember to keep the area clean so no dirt gets into the engine or the fuel rail.
-the fuel will probably still be under some pressure so have a lot of rags handy when you pop off the first injector. just do it slowly. obviously, dont start up the engine if you just spilled fuel all over it.
-lube the o-rings on the injector before pushing them into the fuel rail and engine. Some motor oil would be fine. Nice even pressure when inserting them so the O-ring does not pinch.
-dont over torque the 3 bolts when you put them back in. They insert into the aluminum block so it would be easy to strip them. something like only 10 ftlbs of torque.
-if there is any leaking you'll hear hissing or see fuel. So turn the car on without starting it so that the fuel pump is running and make sure you dont see any fuel.

If the connectors on the harness are the same then you shouldn't need more than a socket wrench and maybe a torque wrench if you want to be perfect about putting the bolts back in.
You may need to loosen the bolt holding the steam line to get the rail out. Nothing special needed for that either. You can leave the fuel rail connected to the fuel lines.
What injectors are you putting in? Do they have the same connectors for the electrical harness?
Here are the torque settings from the ecotec service manual

Like everyone said, it's a pretty easy task. Just take your time and be careful. Getting the plastic clip off the damn stock injector harness beside the motor to install then 60# harness is harder than the actual injector install haha.
very easy. wont take you more than 20 minutes
Here you go. An instructional video I did for the Atom guys last year on changing the injectors. Same engine, different car but it gives you an idea

Thanks for all the help people!! Great video Bolas, now I have a little confidence that I can handle this on my own now.
I do have just one question, I read ina how to that I need a torx socket to get the plastic cover over the fuel rail off.... is that neccessary and what exactly is it?

no if you get the right sized flat head to use that works just don't strip it...thats what i did i didn't feel like looking for that damn thing
its just a certain type of head.. like an allen wrench but more corners kinda...a flathead will work

yea but if you don't have one its not really all that important to go out and buy a simple flathead will do the trick..but yes they are the correct tools and will make the job easier..i'm just saying
