I did a search on here and i thought someone said that the hoses didn't quite fit onto the all metal one. They were too big or something like that. The radiator seems very simple to replace. The hardest parts looks like draining the radiator. Was yours hard to replace? My sniffer seemed to point towards the area around the top of the radiator. Why in the hell did Nissan use plastic? Cheap a$$es! I think they skimmped on everything on the b15. I've been looking at Corollas lately but i don't want more and higher payments, plus i think the SE is quiker. Oh, how is the performance on your all aluminum radiator? I'm not looking to gain hp just no leaks! $259 not bad but i gotta sink $600 into a frigin ac compressor!
