If you had read my reply the first thing I asked was if he put the
thermostat back in... People sometimes amaze me ... when a system is
working as designed don't mess with it... thermostats have been
around for quite sometime and when working properly, function as
designed.. they are however subject to wear and need to be replaced
periodically ... the problem comes when its time to replace them that
all the other system components have been neglected and start to
fail at the same time... now its a game of diagnosis and replacement
by trial and error.... I learned very early that you don't remove a
thermostat...the pressure of the water pump combined with the
pressure by heat buildup overides the cap designed pressure and
usually blows all the coolant out the overflow...if you overfill the
radiator you leave no room for expansion and the same result happens.
I hope all is well with the radiator person and the oletruck is back
on the road!!!
