I just recently purchased a 97 Cadillac catera and the oil cooler for the engine that's located under the intake was not there. Is it a necessary thing to have it if I will be driving it regularly or can I manage without it until I can purchase one.

No, not really. The engine oil cooler lives in the block, under the cover plate between the heads. There's a coolant gallery under there. Notice the oil lines on that plate. It's prone to leaking if the coolant PH leans toward acidic. If it leaks coolant leaks into the oil system, showing as a creamy goo in the coolant reservoir and dipstick. You might see the same residue under the oil filler cap but that may just be condensation that burns off after the engine heats up. Regularly changing the coolant is the best way to prevent this leaking from happening. The oil cooler on the radiator is for the transmission but only on the '99-'01 Cateras if I remember correctly.
Number 18 in the diagram below are the oil cooler and its associated parts. Numbers 1 & 2 are its oil lines.
