The past couple of nights it has been in the low single-digit temps, and I have had a couple of strange things happen with my bird. First, when I would start it, both the "low washer fluid" and "low coolant" lights would blink for a good minute. After about a minute, they would both go off. I have had them come on and stay on before, but never blink, and never at the same time. The second thing is that whenever I get on the brakes and then on the gas, my parking brake light comes on for a split second. This happens regardless of speed, just whenever I get on the brakes for more than about 5 seconds or so. Both of these things happen only when it is really really cold out (the night before last and tonight were 2*F and 1*F respectively, but last night it was around 10*F and it didn't do it). Should I be concerned with these things?
P.S. I have read up on signs of head gasket failure, and I know one of them is a severely fluctuating temp gauge. My temp gauge noticeably will cycle back and forth a bit, but only just noticeably, not way back and forth like is described in a head gasket failure. This only happens in cold weather, though it doesn't necessarily have to be as cold as it has to be for my previously described problems to occur. Should I be concerned about this fluctuation, or is a little bit of fluctuation normal? This should teach me to pay attention to my temp gauge no matter what the outside temp lol.
