I was wondering if anyone could help me out. Today I popped the hood in my car and realized that the coolant in the flow reservoir is quite low.

Is it fine to top it off or should I do a full coolant flush?

Live In Minnesota so it is quite cold here.

 

Well if your due to flush the coolant, You should. If not just top it off.

 

I'd look in the radiator too, I bet that's also low. Top off the radiator then bring up the reservoir to the full mark.

Inspect both after driving for a week or two.

 

I'm just stupid! Didn't realize the coolant went so low, its between the MIN and MAX line. I will flush in the spring when its not so cold out!

 

I would just top it off and check it in a few days. If it's low again then check for leaks.

The manual says the top off procedure is to just fill the reservoir.
