I have to keep adding antifreeze every couple of weeks, no leaks anywhere, has a spell of antifreeze, will spike up to around 230-240 then come back down, Took to the dealer and they says both of my radiators need to be replaced and the small one is on national back order? I guess a lot of people are having this issue. Dealer wants 2100.00 to replace them but can't guarantee me that this is the problem? I've read a lot about a 3 way diverter valve in the cooling system they has been known to fail, anyone else having this issue
