Raise the front end and bring it up to temperature with the cap off. Squeeze the upper and lower hoses and see if it burps. The funnel i listed seals to the radiator and gives you another several inches of fill height.ya - Thats what I was thinking. I just use a funnel and squeeze the top hose. DO we think that would cause these Issues? I don't have a special setup but I don't mind getting one if it will help?
