Like I said, take a whiff of the exhaust especially at startup, as that can give you an idea.

How does the coolant in your radiator look?
Update..........

The exhaust smells like a car with no cat, nothing more.

I couldn't get the cap off the radiator to look at the coolant........

At this point, I would flush the cooling system and fill with nice clean new coolant to the proper level and keep an eye on it in the future.

That is, as mentioned before, unless you have any other reason to suspect that you are burning coolant. Even then, filling with new will give you a benchmark to know if you're using coolant, IMO.

I agree, what does it usually run to have it flushed??

Oh, you caught me off guard there since I usually do my own, but I believe that a lube joint usually charges somewhere in the $40-60 range for a flush and fill.

It'* not really too hard to flush it yourself. You can even get flush kits from your local parts house that, once installed the first time, make it a snap to do after that. And MUCH less costly. But your call.

Well, since I can't get my cap off I was going to have them mess with it, but I will look into the do it yourself kit.........
