I've got 2 leaks : they are both coming off fittings under the car behind the rr wheel. I tried tightening the fittings but they don't seem to budge. One of the lines is connected to the thermostat and is leaking where the hard line transitions to rubber. The leaks are very minor-they don't drip on the floor, but I'm thinking I might as well replace the whole lines if it's not too hard to do.
