Most Chevy Silverado radiators have oil and transmission coolers to help prolong life and performance. All have transmission coolers but fewer have oil coolers.
First of all I think you are confused. The engine oil is not cooled directly by a cooler. The engine its self is cooled by a cooling system. Which uses coolant and a radiator. Coolant travels through the radiator and is cooled by a combination of factors. There are air dams or cowls that gather moving air and direct it through the fins on the radiator. ther is a fan that is temperature sensitive that comes on and blows air across the fins. Most always, there are transmission coolers built into the radiator, but kept separate from the coolant to prevent the fluid from getting too hot and damaging the transmission. On some radiators there are oil coolers built into the radiator to help cool the oil much like the transmission coolers serve.
radiators are cold on the bottom and hot on the top?
I do believe all 88 to 98 silverados
Put all the radiators on! SIMPLE!
No, they used to be made from copper or brass.
No

Interchangeable with what? Nearly all of the body and interior parts interchange with a 1971 Chevelle. Most of the body and interior interchanges with a 1970 Chevelle as well. Rear axle interchanges with ANY '68-'72 GM A body. Engine and transmission interchanges with any Chevy from the 1950's up to the 1990s at least. Front suspension also interchanges with ALL GM A bodies. All small block radiators are interchangeable. All big block radiators are interchangeable. It all really depends on what part you are trying to use/replace.
