I recently had the change done on timing belt and water pump. After that Im losing coolant from the reservoir with every day use. There is no coolant on the floor. I get under the car and find no trace of coolant. Both hoses get real hot when car in operation for 15 min. The car runs smooth and normal. The temperature reading are 203 degrees in idle and 190 running. Why am I losing coolant. Where is it going to?
