I have an 85 7 pass,manual trans that has air bubble problem-the line from fill bottle to resivor worked loose,chopped by fan belt,overheated,I eased it home,replaced the line,put front end up on ramps,filled resivor and refill,ran with rpm@2K,heater on,bled from Kennedy valve on radiator,kept resivor full,got steady flow at first,then as engine heated up,flow stopped.-still have overheat problem,did get some hot coolant out of bleed valve.should I assume it's the thermostst sticking? in theory,by closing resivor and refilling via fill tank,should be able to"recycle" all coolant.(or,I'm way off base) need input on solution to overheat problem.  Thanks everyone, Mike
