Well , after 205k miles, the radiator on our 1999 LC had developed a small leak in the hard plastic top piece right around the radiator filler neck. There is a hairline crack in the plastic. As a temporary fix last night, i put some JB Weld over the crack. no luck, still leaking. I probably didn't rough up the area around the crack well enough. I priced a replacement radiator with a local radiator shop that has worked on our Land Rovers. $300 installed. The dealer wants about $450, just for the radiator. The radiator shop told me that they can change out just the top plastic section and keep the rest of the radiator. Has anyone done that type of repair? I really don't want to do it if it will just mean that we will be back in there doing another fix in 12 months? I have read that everyone has recommended only using the oem radiator. Why, are they really that much better? . I look forward to your comments and recommendations. Phil
