well aint this some crap if i aint ever seen any. i took the 89 for a little testdrive with the new radiator fans. the other day it idled for over 30 minutes and stayed at 185. now going down the road it gets up to 231. i used fans off of different cars. not sure where one came from but it pulls a lot of air but is not shrouded. the other one came from an 82 subaru wagon and it is shrouded. it too pulls a lot of air. i could not fit the stock shroud over both of them like i wanted too.now i have a little 90 f150's radiator. it is the same width as the stock mustang one but it is longer. i did have a 3 core from an 82 truck but it broke and this is the only one i have for now. the block is bored 0.60 over and i know i asked for it. i have no thermo now since the small radiator install. i know averheating is 270 and i am not that worried but would a 2 core aluminum radiator help me lower the temps. what else can i do. i live in texas and it is very hot today
