how do you drain a coolant system on a toyata camry 1997?

Answer 1

Not sure about that specific model, but most car radiators have a small petcock drain valve down at one or the other end of the very bottom of the radiator, on the inside (that is, from the fan side or engine side, the side that faces you once you look under the hood).

Before you loosen that valve, make sure to get a BIG drain pan that will hold several gallons minimum, in some cases it's just as easy to disconnect the lower radiator hose.

Sometimes the valve is really tight, you'll need small pliers to pry it open but be careful, it's a little valve, looks a bit like a T thingy, most open like a soda bottle (counterclock).

Again, it might be easier to pull the lower radiator hose, also you'll want to loosen the radiator / filler cap(s) and don't forget that drain pan. Dispose of properly, antifreeze is a sweet tasting but poisonous substance that animals can and will drink (and it kills them).

Some cars, you may have to pull the fan and shroud.

Answer 2

The other person is correct but remove the radiator cap before you drain. The coolant drains much faster.

Answer 3

on the bottom of the radiator this is a little screw that you turn it a petcock also take the cap off the top this lets air get into it so that It will drain faster.

Answer 4

there should be a drain plug under the radiator.
