Anti-freeze/Coolant issue???

So the other week, I was checking my oil and realized that anti-freeze level was lower since the last time I did an oil change. It was at the full cold line, but it where it is in the picture. That picture is taken when the car has been sitting over-night.

But question is this normal??

If it were mine, I would have the coolant system pressure tested. That would tell you for sure if there's a leak. Or you can put some coolant dye in it & use a blacklight to see if you can find the leak. Start looking at the water pump weep hole.

At the base of the pump pointing towards the ground.

well if it was the water pump, wouldn't i see some coolant on the floor? I am going to take it to dealer and get them to check it, since I still have warranty left on it. I also noticed where the main belt is, all the way on the bottom it looks like a mount, and it looks kinda greasy.

well update... took it in. For the coolant being a little low. They said its normal, and if it was almost empty and an leak somewhere, then for sure it is a leak. But they didn't find anything leaking for coolant

They also found the crank shaft seal leaking. Which they replaced. So question here.. when replacing crank shaft seal, which fuild do they replace as well? it is the engine oil?

Yea the oil, That seal just keeps all the oil from spewing from the engine where the crankshaft comes out

Well guys.. guess what.. coolant reservoir is almost empty.. heard slosching whenever I would turn the car on first. Looked at it today, and was suprised how low it was.. looked under the car, shows some fluid and same on the ground. Looks like it is coming somewhere on top of where the A/C compressor is.. my guess would be water pump..

Water pump is covered under the powertrain warranty.

Whoever told you that is a serious village idiot (please don't tell me it was a dealer mechanic). Measured when the engine is completely cold & the car is level, you shouldn't ever see a significant reservoir coolant level drop. If you do, there is a leak somewhere. A very simple coolant system pressure test will verify whether a leak exist or not.

I had the same problem. I had to fill my coolant every other day and could see it leaking on the ground. This happened last winter. I put some Oil Stop Leak in with every oil change and i put some of that coolant system stop leak in the coolant and havent had to add coolant for nearly a year now and no issues. I put the Oil Stop Leak in the oil because it helps with the gaskets seal. I was worried my head gasket was going out but everything is fine and never overheated and no leaks.

Good thing it's been running fine... any idea where the leak may have been coming from? Reason I ask is because the water pump has weep hole(s) in it designed to leak coolant when the pump is failing or has failed, But since you're not overheating and I assume no abnormal sound then your water pump is probably fine. I just rarely hear about stop leak actually working for an extended period of time.

No problems yet. Once i put the stop leak in it stopped leaking. Hasnt overheated nor has the temp gauge gone past the normal op position. Yes the leak was coming from the passenger side of the engine compartment. Never really pinpointed it but probably the water pump.

Sounds like more GM head gasket issues to me. Not to mention that crappy Dexron coolant.
