Oil cooler bushing for several cars including Chevrolet, GMC, and Cadillac. Many owners of these cars have long complained about the effectiveness of constantly changing the cooler. I have received some requests from those who have struggled to fix the problem, asking the mechanic to change the cooler. In reality, the issue requires a mechanical understanding first to determine the cause of the malfunction and the problem. The cooler is essentially a mini-radiator where radiator water enters to cool only the engine oil. The malfunction lies in the bushing losing its rigidity, which prevents the water and oil passages from separating. This allows oil to enter the water, causing the problem and mixing oil with water. The solution only requires flushing the cooler, then replacing the bushing, and everything will return to normal.
