Chevrolet Caprice 2013 Automatic Gasoline Peace be upon you I have a Caprice and I faced a problem. Whoever has knowledge, please help me. The temperature rises and when I drive it goes down. The radiator returns water to the reservoir, and the reservoir fills up and spills water on the ground. With the knowledge that: I changed the thermostat. I changed the original factory radiator cap. I changed the hoses. I changed the original water. I changed the original water pump. And until now, I am facing the problem.
