Recently, a cosuin of mine had a crack in his radiator of his 1992 Camry. So he brought it over to my dad to fix it with a new radiator. I was helping out my dad and i noticed that there was a pipe which was going to the radiator which said "Transmissoin Fluid." I did check the pipe inside and indeed it was transmission fluid. My question is why does the fluid goes to the raditaor. This is something new i have seen.
