Been seeing issues with water pumps on the car the past few weeks on facebook and other places. Finally got around to opening the hood today on my car and noticed the coolant level in the reservoir was "low" (maybe 2-3 inches below the range lines), but the car hasn't been driven since Thursday afternoon (the car has been sitting the driveway on a slight incline) and my dip stick shows no oil contamination (plus I need to change the oil on it this week)...so should I panic or should I just drive the car and see where the level is after a drive? If I'm little low-what should I add coolant wise? I'm planning on getting the coolant changed out in a couple weeks since the car is about 6 1/2 years old and has about 89K on it.
