How do you replace an 1994 3.1 Oldsmobile Achieva s radiator?
Common hand tools.
It should be the same as a '94 Achieva and it is under the dash by the sterring column. You have to look real good to find it
Most likely your heater core has gone bad.

The four "popular" relays are located on the firewall inside the engine compartment just under the pass wiper blade area. They are located 1-2-3-4 on a bracket. Mark, Raleigh, NC
