Thread: Frozen Coolant

Silly California and its 60 degree weather. Its rained maybe 4 days since fall here in the northern parts of California. I have the northern west coast mentality....kinda like rain

Negative 20 all day yesterday..today bout 1 degree....not even thinking bout starting my nx...

OP, this is the coldest weather the U.S. has had in TWENTY YEARS. That means there's many of our cars which have never seen such cold, especially those who have B14's (1994 was the winter last winter we had these temps) I'd imagine it will be another 10 years before this happens again. So don't feel too bad, but I'd keep it warmed up as possible. We hit -8 this morning which for our area is absolutely ridiculous, and just about 45 minutes north of me at Mount Pocono, hit -16!!!! Any kind of coolant with water mixed in will freeze up for sure at that temperature. You can get yourself a antifreeze tester at Walmart for like $2 (it's a little tube with a ball in it that goes up and down).

As for my car, since I'm still waiting for parts for the Altima, I've been warming the car up throughout the day and drove it last night to operating temp, because I probably have 15% water still in there and I can't park in my garage because a terrible Nissan parts department keeps saying the gasket I need will come tomorrow, everyday. Otherwise B13 would be in the garage with the heat.

The car started fine and everything is good. I drained a gallon of coolant and put 100% back in. This should get me to 50/50 and it will not get as cold as it has been so it should not freeze again. I have a tester and will go out and test it once it cools down.

Fingers crossed I have the same success when I go get my car. I'm not getting it until Thursday though when I know everything will be melted. I stopped back to check on it, the fluid that did thaw drained back into the rad but I could see remnants of ice crystals at the bottom of the over flow tank so I'm just gonna wait till I know I wont have an issue. Nothing is leaking or anything so i dont think anything cracked. I'm doing the same thing though. Hitting it with 100% to top it off from what spilled out then doing a whole flush and refill.......in fact i'm going to do that to all 4 of my cars when the weather permits cuz now I'm paranoid lol

You guys realize that too much coolant will freeze right? After -45 on the tester is FREEZE POINT.

Yes, but there's a reason that they didn't use threaded plugs versus pressed in plugs and it just happened to be in the coolant jackets. There's no press in plugs in the oil galleys. Hence "freeze plugs." But that's not at all what they're for.

Sure there are. Plenty of them.

Here is one right above Greg's finger on a VE head.

That would be a threaded plug, not a press in.

Never mind, I see it. Much less surface area but your point is made.
