Using this transmission cooler is a breeze. First, make sure your truck is turned off and cooled down. Since it's a direct bolt - in replacement, you can simply remove the old cooler and attach this new one in its place. When installing, double - check that all connections are tight to prevent any fluid leaks. During normal use, keep an eye on your truck's transmission temperature. If it starts to rise unusually, it might be a sign of a problem. For maintenance, you don't need to do much. Every few months, visually inspect the cooler for any signs of damage, like dents or cracks. Also, check the fluid level and its color. If the fluid looks dirty or has a burnt smell, it might be time for a fluid change. This cooler is built tough, but gentle driving can help it last even longer. Avoid pushing your truck too hard in extreme conditions whenever possible.
