If you haven’t done it or are unsure how old it is. Believe me, it will save you from some major headaches. A while back I changed the valve cover gaskets on my ‘03 base model. After a few days I went to check the oil level and to see I’d finally stopped the leak. When I opened the hood I found nearly every surface covered in dried pink spray. The overflow tank was empty and it took about a half gallon of antifreeze to fill the rad back up.

Oddly the car never ran hot or indicated any kind of low coolant. After I refilled the radiator it leaked steadily between the plastic tanks and aluminum fins. It took me three aftermarket radiators (NAPA Premium leaked from the upper tank, KOYO trailer towing model was crushed in shipping) to finally get one that didn’t leak. I finally ended up with a Duralast from AZ (Don’t hate. They were the only ones who could get one on a Sunday).

The car car always ran perfectly and the temp gauge never got above the halfway point even on the hottest days (I Iive in the Deep South. Any further south and I’d be standing in the Gulf of Mexico). So it was pretty is to figure out that the radiator cap failed, overpressured the system, and led to massive coolant loss. Which could have led to a massive engine meltdown (thankfully it didn’t) A new radiator cap is incredibly cheap, takes seconds to change, and would’ve saved me from headaches and lost hours. Do yourself a big favor and change yours today.
