Default Coolant issue/question

Just the other day was the coldest day to date in NE. (Glad I got that heat fixed). I noticed that once I got to work and parked my car ( I usually sit for a few minutes to warm up and drink some coffee) I noticed that my Low Coolant light came on. Hmm how could this be? I have replaced the LIM UIM gaskets not too long ago.

My question is, could the sudden drop in temperature cause the coolant level to drop?

I did all of the usual checking of the oil and what not and everything is A ok there. I did fill the overflow tank to the full cold line after I got out of work and back to my car and am now keeping an eye on it.

Anyone have any ideas where my coolant went?

Air pockets have slowly worked out of the system since you and Boosty did your gasket work.

Have you watched the coolant level regularly since then? Or is it possible it slowly went down over time?

What is collant? Please change title.

On extreme cold snaps like this.. some people experience an issue. I think it'* caused from the thermostat not opening as usual or being momentarily stuck. You lose some coolant through the overflow and find later that you are a little low.

I doubt we had that much air, especially the way you kept burping it.

Bill Wren: I have kept an eye on it since the intake job with no loss. As far as I can tell I havent had any leaks in the system at all, so thats why I was thinking the sudden drop in temperature may have caused it.

Boosty: Title fixed. Thanks!! Yeah I bled the system allot afterwards since I was concerned of the higher temps while driving. But im thinking that the cold snap also may be to blame on this one. I'll be keeping a close eye on it!!

I would do a simple check to make sure your plug into the coolant level sensor is fully inserted.

Did you do a full coolant swap when doing the gaskets?

I'm thinking you may need a stronger mixture of coolant (like 60/40). The blocks on out cars just hold too much water after you flush them to get a strong enough mixture for NE winters. That is if you did flush her with water.

No flush was neccessary when the intake was done. We just topped it off and bled the system. I did have to bleed it a few times afterwards because I would get a 220 reading on my temp gauge, which I thought was because of air in the system, but that has since went away and its running 180-190

cold weather does retrack the coolant and its possible if the overflow was low it could have taken in air. I would keep an eye on the coolant level topping off the overflow and see how it goes.

Have you checked the low coolant sensor in the radiator? Mine did the same thing, showed low coolant, and I found my sensor in the radiator went bad. Just a thought.
