Thanks for the replies guys. My phone died on the way to my buddy’s place so I wasn’t able to read these replies. We used water from his hose to mix with full strength and then tested for the correct blend. I guess we’ll see what happens. If I start seeing anything funny, I’ll just dump it all again and use distilled water.
JTF, is there a test kit I can get that will tell me if there’s been a chemical reaction in the coolant that could lead to some crap eating at my gaskets?
I’m thinking it’s possible I may have had air in my system…but not sure. I had a flush done and the coolant tank was topped off after burping the system. I drove home last night, parked the car, and this morning noticed the coolant in the tank was low – figured just more air or whatever.
I then topped off the level and drove 130 miles to my parent’s place this morning. Before I left a couple hours ago (now home) I had to top off just a little bit more. My car’s cooling off right now so I’ll see if it’s still below the full line in awhile. I haven’t noticed any leaks of any kind though.

The radiator doesn’t have a cap on my car. The overflow tank is where the pressurized cap is located. It’s the LZ9 3.9 engine for the G6 GTP.

It’s the 3.9 engine. The lower intake gasket was replaced last month.
I think the problem may be solved. I noticed a couple drips slowly forming at the overflow tube off the overflow tank after I turned the car off. I thought that was odd so I squeezed the lower tube (off the head I think) and the overflow hose forced out coolant (a couple drops).
I then inspected the cap and noticed the seal was cracked. That’s got to be my problem right?
I ordered a new coolant overflow tank cap…hoping that solves the problem.
Question is: WHY didn’t coolant drip out with 15 pounds of pressure in the system during the pressure test?

Perhaps you could just run a new switch to the fan…then you get to control when and how long it stays on.

Hey guys, thanks for offering ideas and the video too. I did cold pressure test to see if that changed anything and it didnt. The pressure had zero loss and its frustrating. Today when getting on the highway I romped on it and within a couple seconds I smelled coolant. My window was down… I did a thorough inspection of the engine bay and no leaks that I could see. I’m going to replace the over flow tank cap…
I have a 2006 pontiac g6 gtp with just over 80k miles. It drives mint, just has a lingering coolant smell…so annoying.

Thanks for responding guys. I forgot to mention but i did do a pressure test on the cooling system when it was normal operating temp and no loss of pressure resulted…
There is no oil in the coolant.
I’ll check all my hoses for possible leaks and fittings. Hopefully something positive comes up.
