Car with no anti-freeze.
My race car does not have anti freeze. Water only.
How cold does it need to be overnight, sustained, to freeze the block or cause damage? Thanks. I heard putting a single light bulb under the hood is enough to keep the temps above freezing. Supposed to drop to as low as 24° this week. KT

Anti freeze is good stuff. Good for the car that is. Don't let the cat or dog near the stuff. Why don't you just put some glycol in and not worry.

At 24 I would be worried.

Too risky to rely on online tips. Put a gallon of plain green peak brand in there. Plus your water pump must be pissed at you for running pure water. Those seals and bushings need the lube provided by the coolant mix.

An incandescent light bulb (assuming it stays lit and doesn't cause a fire) will put out a pile of heat but at 24 degrees, a little wind and no insulation could be enough to freeze it even with the bulb going. Water conducts heat (or cold) very well and radiators make sure that happens.

Thanks for the replies.
I'm not allowed to use antifreeze in the car while on track. Maybe I should just drain it? We are racing this weekend and the car will be outdoors overnight at the track. KT

If it is pure water then yes drain it. Expanding water will push out freeze plugs or crack the block/heads so easily.

Better to be safe. KT

Why not throw some RV antifreeze in for the down season and drain it before next season. Non toxic and easy to dilute and dispose of. Even if you added some of this to the mix and then drain it, it may stop some of the water that doesn't drain from freezing and damaging your block.
Do you use Wetter Water or something that has some rust inhibitors or just straight water?

KT, water wetter is non-glycol and will make the cooling system happier.

What no one has mentioned, at least I don't think no one did, is not the ambient air temp, in this case possibly 24 degrees BUT the temp you hit once the car/truck gets moving air into the radiator and engine area. The chill factor will make it lower. I was surprised to hear there is none in the cooling system?

I just went out and 'pulled the plug'.
I'll fill it again before I load out on Friday. Then drain it again at the track Friday night. I may have a garage to keep it in Saturday night. If not, draining and refilling is not that big of a deal. Also, for those that would like to follow our season ender: Specialty Timing - Lemons Live Timing Arse-Freeze-Apalooza - 2013 - 24 Hours of LeMons KT

John, once he starts the car it's of no concern.. engine heat will take care of that almost instantly.
Oh Trek,, just had a reference point.. after one race last March,, I forgot to drain Sparty and came over the pass.. sure enough the back sensor cover broke in two.. For the two minutes it takes I'd drain it , ,just remember to fill it up before the race.

24 deg. for an hour or two won,t likely freeze anything.
I doubt I could freeze a bucket of water in my freezer that fast. If it stays below freezing all night then maybe. If worried I would drain it .. Tracks probably don,t like glycol antifreeze because it,s slippery if leaked on the track. What about alcohol as antifreeze ? It won,t be slippery and won,t be visable in the coolant water during tech inspection.

LeMons rules do not allow for any additives to the cooling system:
