you have to put the radiator fluid in the overflow. This is the only way.
Brake fluid location in 1992 Mazda mpv
If a Mazda MPV is leaking yellow fluid then it is possible that the fluid is brake fluid. It is best to take the car to a mechanic right away.
I remove the transmission dip stick and insert a funnel to fill it right there.
Follow the lower radiator hose from the radiator to the thermostat.
Between the bottom radiator hose and the radiator. On the engine side of the hose.
You could try soldering
Dexron III
the bottom radiator hose goes right to it
The thermostat on a 1997 Mazda MPV is located on top of the engine, under the upper radiator hose. It controls the flow of coolant through the vehicle.
Mazda MPV was created in 1989.
It stands for Engine Coolant Temperature. I believe it is wired up to your hot/cold gauge in the dashboard of the vehicle. It screws into the side of the engine and monitors the temp of your radiator fluid as it circulates.
In the upper radiator hose, next to the side of the block (look above the alternator).
