1968 Bronco
1970 302 Stock not too sure, rebuilt 30,000 or so
3spd
Stock radiatior and fan I believe, it looks like from 68
When Bronco parked and started runs fine, been doing two mile runs, starts to boilover at mile one, and when I get back theres a thumping noise, sounds like from the bottom of radiator or hose, like pressure needs to get out or something,
sometime sounds like maybe pump is dry or the alternator maybe cant tell
Problem started when changed the T-stat to 180 from the 160 I think
No problems before that besides heat lower than now, radiator had a screw and clamp on the overflow hose and had no aux tank
Have aux tank and new 13lb radiator cap now, seen spill into and sounded like air trying to get out of hose on filler neck and cap
Tried to "burp", let run with cap off and boom seem like a huge air bubble behind antifreeze happened a couple times, not too sure if thats right or something else is the problem, wondering is there equalization to air antifreeze mixture or is the excess air or steam being produced come out the filler neck hose
Have watched the flow take place when T-stat opens, like a drop and fill, with the flow going from driver to passenger direction
Temp right now is about 9 with wind chill below zero for sure, still happening to boilover and stuff, so outside temp shouldnt be a problem would it
Read somewhere on here to fill from heater hose to replace lost antifreeze in manifold could that be my only option or did I turn an ant hill into a mountain
