Do you have to evacuate the A/C to take out the heating coil? 2000 Chevy Silverado 2 wheel driveThanks!

do you mean heater core? is yours leaking or plugged?

no its removed from under the right side of the dash

Thanks, guys. Yes, I meant "core", and I do have to evacuate the a/c from what I read elsewhere. I appreciate your time.

in answering your question, yes, the ac has to be evacuated. i would get a shop to recover it for you and then return to them to charge it when you are done.

I understand, thanks. I have the proper equipment here to capture and to charge it back up. Thanks.

ive been replacing heater cores 20 years and i never evacuated the a/c.the a/c and heater work off different cores??????
