hmmmm, i need to check this bottom pieces that are to keep air going through radiator. i dont have those parts!!! what are they called and where in thr heck do i get some??? i do have the 400 and the fillers are in the top part but nothing below under or beside radiator. it stays cool as long as i keep it moving at around 140 or so, ok maybe 65mph but when i cruise or stay still it gets warmed up so much that if i shut it off it doesnt want to start back up cuz i think its getting my starter too hot.
