Question regarding removing #2 injector - LLY

[wilsonck]

To remove the #2 injector on a LLY, do you need to drain the coolant and then remove whatever pipe is above the injector or will it come out without removing this pipe?

 

[schulte]

Yes

The injector is very long and the coolant pipe will be in the way

you dont have to drain the system dry, just enough so that coolant tube drains.

 

[wilsonck]

thanks. I have replaced a couple already, so I know they are fairly long and it didn't appear that it would come out with that pipe there.

 

[dmax711]

good luck, and be very very clean with the new injectors. NO PAPER TOWELS.

I have changed them without touching that coolant pipe.

 

[wilsonck]

I had another guy tell me that too, so maybe I will try that first.

thanks guys.

Just disconnect the hose from the radiator, unbolt the three bolts that secure the coolant pipe down, and rotate the pipe up, still keeping it attached to the thermostat housing.

You don't have to touch that pipe at all or disconnect anything from the radiator. Just use a wrench to get that injector line loose from the top of the injector and a crow foot to get the line loose from the rail then pivot the line around and out from under the upper coolant pipe. Once that is out of the way, there is tons of room to get the injector out. You may have to pop it up a little to get the hold down off then rotate it so the fuel line connector is on the bottom to get it to clear to come out. I'm sure you can figure it out.
