nlz1711 0 Posted October 8, 2018 Hi All, I have recently got a split in my radiator so I purchased a 2nd hand one as Lexus cant get one for a while. The new radiator is out of a GS430 but it has no radiator cap. Is this something I can use? I have looked at some pictures and the expansion tank looks the same. If I do use this where do you top up the coolant? Sorry if this is a stupid question. Thanks, Neil. Share this post Link to post Share on other sites
