I have a leak in my 86 roadster's heater core and I wanted to see if you may have done a how to tech article that was published in a past edition. I have a service manual but it is vague.

if you google C4 heater core replacement.. there are a bunch of articles out there on it..  its not impossible to change.. just tucked in and hard to get to..

there were some articles around the 2 corvette web sites here..but i could not find them..

there is a lot of forum talk about this.. and you will probably want to invest in a set of 1/4" extensions with ball ends.. so the socket will swivel when you get it into close places..

from autozone. and some other stores.
