My gf's 1999 crv is spilling or spraying coolant. When i open the hood, there's coolant spray on the hood and near the throttle body. I refilled the coolant reservoir to full and proceed to drive her home and whenever I am at a stop, the temp gauge goes up and moves normal when I start driving When I checked the reservoir again, the was 1/2 gone within maybe 10 miles of filling up. Please help me pinpoint the problem. thanks!!
