Can anyone please suggest a simple heat shield design/material to stop heat from the header from boiling the coolant at idle? I'd like to stop along a trail for 30 seconds or so at idle without loosing coolant. I also worry about heat damage to the rubber radiator hose that's so close to the header. There's various insulation materials that could be wrapped around the header pipe, but this would look pretty tacky. I'm wondering if there are some other more clever things that others have used. Thanks.
