I'm experiencing something srange....When I start the car up my temp indicator(outside, not the coolant) starts off at -40C and as I drive off, it slowly climes up to the correct temperature (takes about a good 15 minutes). When I shut her down It decreases back to -40, not right away though. If she sits for 10 minutes it'll start from around -10C. If she sits for an hour it'll go back to -40C. So it's not like it resets itself to -40C when I turn off the ignition. Has anyone experienced this, ever? What the hell should I look for? [80?]
