wildebill308 Report post Posted April 11, 2019 That page only talks about draining the coolant if you are removing the engine. Nothing telling where the drain is or how to fill. About all I can offer is call 24/7/365 CUSTOMER SUPPORT United States & Canada:888-GENERAC (888-436-3722) see if they can help. Bill Share this post Link to post Share on other sites
richard5933 Report post Posted April 11, 2019 See page 88, right-hand image. There is also a coolant drain shown on the engine exploded view, page 77, item 24. Share this post Link to post Share on other sites
craigc51 Report post Posted April 11, 2019 Thanks to all who responded. I finally found out there’s a small bleed screw on the bottom of the unit. You don’t have to remove it all the way to drain the coolant . there’s also a petcock right above the engine oil filter to drain coolant out of the motor Share this post Link to post Share on other sites
