I have an 01 Montero ( not sport ) and I found the container for rear washer fluid is in the rear door, under a plastic flap. Actually the rear door has a pocket in it, and this flap was in the pocket area. Maybe the same for the sport - I don't know.
On a Mitsubishi Montero Sport, the front bottle, or tank, for the windshield washer fluid is right behind the passenger headlight in the engine. It is just inside the passenger front bumper.
Follow the hoses from the washer outlet spray heads backward to the washer reservoir.

Behind the front bumper on the passenger side. The pump is attached to the bottom of the tank.
Your washer fluid is low, or the indicator is stuck. The washer bottle would have to be removed and checked.
front-pop hood, its towards the passenger side in the front, by the grill. rear-open latch, its on the passenger side in the space the rear hatch sits. yes it has 2 different tanks on these cars.
It's on the door in the pouch
Manual for 2003 Montero Sport with a 3.5 liter says 10.2 quarts.
How to replace wiper motor on a 1998 montero sport mitsubishi
there's a cap on every fluid of every car. if yours is missing, its no big deal, just put another cap over it, or tinfoil works to, as long as it doesnt get stuck inside the tank. you just don't want dirt and crap getting in there while your using your wipers.
the tank is behind the front bumper passenger side......to fill...open hood and filler is located on the end side of the radiator...open cap of filler...not the radiator cap.
If it's anything like my 1998 Explorer sport here it goes. Of course pop the hood. Stand on the right side of the engine compartment where the washer fluid reservoir is. While looking at the washer fluid reservoir look on the lower left side of the reservoir. There will be a small black item with an electrical connection and two hoses attached to it. That is the washer pump.
