I have a 86 TA it had a 5.0 org in it for a motor... someone put a 5.7 and I have the headaches... I'm getting code 15 and 32 I put a diff Coolant temp sensor on the drivers side, I see the one on the passingers side is plugged which I assume is for the fan... I wired the fan so it turns on as soon as the key turns on.... I put a new water pump in last fall seems fine for awhile now it acting up again. I think last year I figure the motor was like from 82 83...
looks like a new rad in it already... any ideas ??
