Default Thermostat / overheating issues Sort of odd issue

First off, thanks for all the help guys...I don't know what I'd do without you.

Here's the problem. I start my car, and wait for it to get to operating temp. Ill drive to my destination and the moment i'm at a standstill, the car will slowly start to overheat. I've carefully monitored it to find the issue, and it never goes to red.

It's a 2.5T motor w/ roughly 50K.

No leaks at all, i have enough coolant. All hoses appear to be functioning properly.

Is this a thermostat issue?

To determine that you have enough coolant, did you just look at the overflow?

It sounds to me like there is a bubble in your system. Even with a bad Tstat it would take a second to start cooking. With a bubble, it does what you described (mine has done it before).

Thanks, should I just burp the system?

Burp the system. I would do a 30/70 ratio of coolant to distilled water or a 50/50 (if it gets real cold where you are) and one bottle of Redline water wetter to the mix.

I had the same overheating problem when was at at a stop/standstill. I did the 30/70/Redline water wetter and I also put in a Crucial Cool Safe T-stat. I have not had a problem since (also have cooler temps then ever).

I was eyeing the Grimmspeed thermostat...but I will try what you suggested and see where it gets me

Thanks!

I totally forgot to update!

Yes, I fixed it. Just a simple burp of the system. Took me 5 minutes.
