You probably will want to remove the fans for more room (easy to do), but you don't need to remove the radiator.

A '94 will take a specific year. A Delphi is a good brand. Not cheap, but when you buy a cheap one, it may quit on you in a day or two, if it even starts.

93/94 use an unvented Opti, driven by a splined driveshaft. 95-97 use a vented Opti, driven by the cam dowel pin. They are not interchangeable. Also consider an AC Delco replacement.

Lol I didn't pull the fans out.... no wonder it was a pain in the butt to get the water pump on,but still was able to get it in.

Donkey77 (or anyone), if you find an AC Delco opti for a 94, please let me know where. I can't find one anywhere.

Re: rad removal 94z28

The only AC Delco optis I've seen lately have been rebuilt units. Last time I looked at Rock Auto they had new Delphi units. You might check Amazon as well.
