2003 Chevrolet Silverado 1500 - Oil Cooler Mounting Kit

The engine oil cooler maintains oil temperature to ensure that it does not reach dangerously high levels that could cause it to burn or evaporate. Oil coolers are often mounted in front of the radiator, and may use specialized mounting hardware to keep the heat exchanger in place and prevent looseness or vibrations that could lead to damage or premature wear. Some oil coolers may instead be mounted elsewhere in the engine compartment and require a bracket to remain in place during operation.
