How long to wait before opening radiator cap?

How long should I wait after a over heat?

 

[murdocthc]

When it cools down and there is no steam...either that or you can pop it while its still hot to let the pressure out and let it cool down faster

Gloves, wrench and don't look at it when you pop that sob.

Well you can if you look away and have a duty towel, and are protected ha ha!

I remember that same thing happen to me on a snow day. "Oh, boy" I freeze my ass off.

Reminds me of the time I had to pull over and change my tire on the side of Interstate 87 at 3AM in a near fricken blizzard because I had a flat.

Exactly! The key is to use a towel draped over everything to deflect the initial steam burst. Putthe towel over the cap, turn cap enough to open cap to first position and get out of the way!

little trick if your too low on coolant and you don't want to blow hot steam in your face. Take your reservoir take and fill it with cold water. Flip it upside down and squeeze the water into the radiator. will cool of faster so you can pop the cap sooner than later. That it if your reservoir is removable. Mine in on my honda is..It just clips into place.

This is what I always did. The bigger and thicker the towel the better. As long as its doubled or even quadrupled over, and you bunch it around the cap and turn you'll be fine. Gloves are a good idea in addition.

I would think, if it's out of water, put water in the reservoir like you said, and it should suck it up by itself.
Also, if you are near a hose when you're overheated, spray water on the radiator to cool things down so the cap can be removed.

If you can squeez the top hose to the radiator easily
Then you can removed the cap
But still take precautions

This seems like a bad idea. You don't want to cool it off so fast that it cracks the radiator.

I've never tried it, so I don't know if that's a risk. Maybe with all the surface area it's not that big of a deal?
