Thanks. Think I can borrow that if not I'll order it.!!!Pressure test the cooling system, then cool it off and put the gauge on and start...see if the pressure comes up quick.
Just did the head gaskets on a '66 289 ford for this exact issue.

Ain't Local Napa a ol gals dream? Small town AmericaLocal parts stores should have a loaner....for free.
You just have to leave a deposit equal to the price.
Probably not something you will need again.
Not a difficult project, just a pain in the ass.
Thanks I'll grab a new cap when I borrow the guage tomorrow.Could also be as simple as the radiator cap not holding pressure. Each psi raises the boiling point 3 degrees, so a 15 psi cap raises the boiling point 45 degrees.
Omg ,DUh! forgot about that thanks!Didn’t see this mentioned, but check the oil on the dipstick.
Any moisture in the oil will show a milky color on dipstick, sure sign of water leakage internally
Head gasket or cracked head most likely.
Thanks I'll check that!You might take a garden hose or pressure washer and wash the fins of the radiator out. Grass seed dirt and grime would stop air flow thru the radiator to cool.
Bubbles might appear in the coolant if head is cracked in a way that compression is pushing into the water system.
Starting from a cold engine does it go straight into over heating or does it cycle till it overheats.
Thanks I'll check that too!If it has an electric fan be sure that it is working. Old style clutch fans can get weak and free spin not drawing enough air thru the radiator.
ThanksSkillset, Toolset, Mindset-sounds like you got it covered.
