1989 Chevy Caprice Radiator

I don't know that there is a step by step insruction on that that is much help.

Basically, you drain the rad. Remove the top shroud to acces the rad. Remove the cooler lines and hoses. Lift it out and re-install.

The worst part of this one is getting the right rad. These had various systems that included different core sizes and coolers. Try hard to verify you have the right one before you pull it out.
