What is the preferred way to remove the radiator on a 300D turbo car? The issue is the oil cooler which is bolted to the radiator with two brackets, and the bottom one is hard to access with the oil cooler in place. The way I see it the easiest way is to disconnect the oil cooler lines and remove the radiator/oil cooler as one unit. Then bolt up the oil cooler to the new radiator and reinstall. Am I correct in this assumption?
