Sorry, I forget what I told who to do :bonkers:.sdpj said:thanks, you guys are awesome. how could i tell if the radiator cap is bad, actually i assume you guys mean the purge tank cap. ranger, i have checked the purge line, that was one of the first things you told me to do, its good to go. also can i flush the radiator out myslef or do i need to take it somewhere. hopefully its something simple. ill see what i can do.
