Does this have the overflow jug with a radiator cap?

Yes on the overflow tank has a plastic cap the problem is intermittent sometimes it will go for days before it acts up we took the top radiator hose off and filled it up

They make an air bleeder that screws on top of the overflow jug. You can buy these at advance, autozone or harbor freight This is the only way to truly bleed the system.
