I've heard a "sloshing" sound at times on those rare occurances that I've been with my Wife in the HHR. What I hear is definitely from the rear and I'm assuming there are no, or not enough, baffles in the gas tank. I live in fear that some of the problems you folks are having might pop up in our HHR and my Wife will never notice it since she's the only one driving it! I had just that happen many years ago with a different Wife, and a different car!! She fried the engine!!

 

As an update... added 12fl. oz. of (RedLine) 'Water Wetter' to the overflow tank 2 days ago and haven't seen temp's in excess of 196 since!!!! Granted, most of my driving is expressway, however, when I stop- it's usually in some conjested traffic (stop-n-go) area. Although the analog needle never moved, the digital reading on the DIC fluctuated quite a bit. The hottest it hit was 196 ... and only on 2 brief occasions at that. Freeway driving neted an average of 186*. Not a bad investment for $8 !
O-yea... almost forgot. For comparisons sake, it was 92* in Detroit yesterday with 76% humidity.

 

Ya I Have The Same Thing With The Heater Thing The Slushing Water Noise Its Been A Month With It And Its Bad What Should I Do

 

Take it to your dealer and start a NEW thread.

 

welcome...

how about some info on the TR 04

 

If you have the same problem my wife's had...your coolant is too low. It caused her car to overheat and messed up the cylinder head at 400 miles. It is fixed and no problems since. Her car now has almost 8k miles.
