V02 was a four core radiator and a different fan clutch that came with the towing package.

What is the towing package?

So I have to buy the thermal fan cluch and which kind of fan I have to buy and where?Thanks!

You should not have to buy a different fan if you have the original 7 blade fan. If you decide to buy a thermal fan clutch, the 7 blade fan will bolt onto the new fan clutch.

Are you sure the Olds 403 has 7 instead of 6 blade?

Yes, Olds 403 with a/c has a 7 blade fan.

Old post, incomplete info that matters.

That depends on year and options if it had the 7-blade fan. The 6-blade fan was larger diameter, had deeper pitch and blade size and was for HD cooling with AC. Possibly not available in 79 with all the extras, his was a 78.
