Pretty sure, yes. I had a mechanic tell me that around Christmas. I was having problems with it getting really hot on long highway trips (4-6 hours at 70-90mph), and I would have to refill the radiator once in that time interval). I had it checked out while I was out of town and that is what he told me. Decided to wait until I could have my hometown mech give me a more unbiased opinion, and he concurred.

Now it gets really hot after driving around town for 10-15 minutes, but if I only drive back and forth to work (2 miles one way), and keep the coolant full, its runs fine.
