Now that the cold weather is here, i've noticed that my car is having a hard time to hold onto warm temperature. Generally it takes at least 5 minutes to reach running temp and that is only if the heat is off. If i turn the heat on, it will float around 1/4 - 3/8 temp indefinitely. Sometimes reaching running temperature. Sometimes occasionally falling back down. I don't think its the thermostat, as i replaced that roughly a 2 years ago. On my ride home today i had to periodically turn the heat off so my motor could return to temp. Very frustrating on a cold day. coolant isn't low, oil needs to be done pretty soon.
Any ideas?
