Hello all:
First time posting, great info here. I'm here for my brother who just picked up a 2005 pathfinder se with 130k miles at a low price ($3k) because it needed smog work. Codes p0430, p1247, p0507 and couple other emissions related I can't remember.
I'm the DIY'r in the family and so far Replaced Drivers side cat conv., a/f sensors, complete intake and exhaust gaskets, plugs, oil and oil filter housing gasket/o-ring, throttle body cleaned, throttle position relearn, air filter, mass sensor clean, and replaced leaking fuel injector O-rings. $1250 later ($800 for cat alone thanks to CA emissions rules), got rid of all emissions codes and passed smog with flying colors. Now sounds quiet and runs strong. Fuel mileage is on par with estimated 15-21 mpg.
My main concern after coming across lots of posts regarding coolant leaking into transmission and causing eventual problems/failure. Should I replace the radiator since I don't have any knowledge of prior service? I also read about a bypass lots have done to reduce/eliminate the possibility of cross contamination from coolant.
Your help and opinions are appreciated.
Thanks
