It fel inside of the coolant reservoir?

Take it out

it doesn't even matter... I probably have a wrench or two floating around my engine compartment- 200k miles strong and keeping on going.

Flip your car

That's good. That means that if the temperature drops down to negative 35, it still won't freeze and damage your car.

@@javaman2883 what dose it mean if the red and blue ball doesn't float at all they just drop to the bottom!!

It’s good means ur engine won’t freeze and possibly crack until it gets to -40°

@@Nicole-dj3jf probably means your antifreeze is not strong enough and needs to be replaced.

It is usually bright green or orange

I would say it probably needs tested and most likely flushed and refilled. Sounds like water in the system causing corrosion.

The color varies by vehicle, but if it's a dark brown then it probably used to be a golden color and is now dirty.

Looks like a pressurized cap, so there may not be a radiator cap to check from. Unless you suggest removing one of the hoses, which means you'll need coolant on hand. Nvm testing it, just spill some and replace the exact amount you spilled or you risk an air pocket in the system.

some vehicles hav only cap at reservoir

2 balls are fine, it's when you're down to 1 ball, that's a problem.

Was that a sexual joke tigerbalm?

1 or 2 balls are fine for some areas, hot climates where freezing temperatures are rare. Remember that at 1 ball, that rare time it gets near 20 degrees F can mean replacing a radiator.

I live in South Carolina and mine has 2 balls... I know it will never get close to 5 degrees so that works for me. If you live in a warmer climate you can use less antifreeze and more water if you want because it will be less corrosive to your car's coolant system.

Actually, it's the opposite. Antifreeze has corrosion inhibitors in it and is LESS corrosive than ordinary water.@@grahammckain4492
