2002 Pathfinder Cooling System Change

Nov 09, 2010 4 Replies

I tried to find a radiator drain c*ck for my 2002 Pathfinder. Finally gave up and inserted a small diameter4' long tube into the radiator cap and snaked it back toward the firewall and got about 3/4 gallon of old antifreeze/water out. Replaced it with a 50-50 mix of new antifreeze and water and put more of the same into the overflow reservoir. never did find anything looking like a drain c*ck or plug, and got tired of scooting around on my backside under the front of the vehicle.



Can anyone tell me the actual factory-recommended method of changing the antifreeze/water mix in the cooling system?

There is no 'drain c*ck'. It is a screw-in plug. Look at the bottom back side of the radiator on the driver's side. There is a white plastic plug with 'butterfly' wings that unscrews. here's a pic of the plug.

The drain c*ck is there (unless you have an aftermarket radiator?). Look on the back side of the radiator near the corner just above a flat metal brace that runs under the radiator. I don't remember which side, but it is obvious once you know to look above the brace.

It does not have a protruding handle, but rather a plastic screw flush with the hole. The less messy way to drain it is to first remove that deftly placed brace.

For future reference - the preferred method of draining this radiator is of course through the drain plug. If you ever are faced with a radiator that does not have a drain (some domestic cars are like that), the preferred method is to remove the bottom radiator hose at the radiator.

Bill,
