Flushing cooling system 2003 Pathfinder

Postby Micallen » Fri May 04, 2018 1:54 pm

I used to flush coolant by running engine with radiator drain open, water hose in top of radiator constantly filling. After several minutes of that all the existing coolant is replaced with tap water. Then I would remove hose, let it run another minute or 2, then turn engine off. Then of course I would close radiator drain and fill with coolant/water mix.



Is that OK with the Pathfinder? Or would I theoretically need to "Flush" it with distilled water??
