How do you drain radiator?

7 Answers

if you cannot find the "petcock" at the bottom of the radiator...pull the lower hose OFF...catch all fluids to bring back to the autoparts store for recycling~


I think I see the petcock. How do you open it?

lefty-loosey...rightey-tightey...kind 0 kindy-garten but is true~

you could use a pliers...but if it's a plastic one would go gentle with that~


How do you get to it? Get under the car? From th3e top?

use a long needlenose pliers...honestly HAS to be at the lowest part on your radiator and SHOULD be easy to get to....after all is there so that you CAN flush the coolant~
