2001, 5.9 liter V8, 180,000 mi
It has this tiny coolant leak. Left bank near firewall. Its the coolant leaking to the atmosphere. No evidence of coolant in oil and #7 spark plug looks fine. Not even enough to drip or leave a trail. I can smell it when getting out after driving it, and can just barely see a mist when warmed up and idling. When I drove every day (about 250 miles/week) I would have to add 1-2 liters of fluid every month. Would rather not replace the head gasket if I can avoid it. So:
- Would it help to re-torque the head?
- Any thoughts on the radiator stop-leak products?
