sampaula Posted October 26, 2009 Share Posted October 26, 2009 Hello, Did anyone have the same problem with the radiator light stays on after you start the engine. It does turn off after few minutes. What causes that I have coolant in the coolant tank too. Can some answer this for me what do I need to do to solve this issue. Thanks, sam Quote Link to comment Share on other sites More sharing options...
