LT4 intake R and R question.
I need to replace intake gaskets on my LT4. I have a service manual that says I should drain the coolant. It doesn't appear that coolant runs through the intake. Do I really need to drain it? If so I'll do a coolant replacement that wasn't scheduled until this fall.
Thanks,
Thanks,

I'm sure it's because the coolant passing through the TB that they say this. With a suitable clamp these small lines could be pinched off. All of the manuals I've seen, including my factory one I believe, would have you remove the fuel rails, injectors, etc. Why? To simply R&R the intakes on these engines, that's totally unneccesary. Relieve the pressure in the fuel system, remove the two braided hoses, throttle and transmission cable, (if equipped) hoses, piping and wiring as needed. Then unbolt it and remove it. It's really very easy on these cars. Also the TB can remain in place bolted to the intake.
