Second Stallion in the stable. Picked up an used SRT-6 Roadster over the weekend. Has some minor issues but after a 17 hour drive I am still very happy to have the soft top.

First thing I noticed after 6-8 hours of driving was a low coolant light. I could find no leaks or wetness under the car or in the engine bay and the oil was at the correct level and not milky. I filled the tank with 50/50 coolant thinking there may be some air burping from the system after a recent repair. 6-8 hours later same issue, this time I went to straight water. I figuered if the coolant is leaking to the most common place, "the intercooler" it is better to have just water being burned. Have you guys heard of any other missing water leaks other then the intercooler?

Second, I noted that the car acted a little like it had an un-balanced rear wheel, more so when under hard power and has a roaring wobble noise coming from the lower middle to back of the car. I had the balance of the tires checked, no problem. I took comparison rides with my SRT Coupe to be certain and there is much more of a vibration/unbalanced roar noise in the Roadster. I figure the most likely causes could be drive shaft center bearing, wheel bearing or rear end? What do you guys think?

Thanks
