Lake Mead Monster 0 Report post Posted April 11, 2014 I have a 2004 298SC with a Kohler 5.0 KW Generator that is leaking coolant. The coolant seems to be leaking when the generator is not even running. It appears the coolant may be leaking from somewhere near the fuel filter area but I could be off if it is "traveling" from another area. The generator has 490 hours on it. Are there any common seals or areas that are prone to this type of coolant leak? Any help or advice would be appreciated. Share this post Link to post Share on other sites
