Thermostat wont open
My 97 dodge ram was running hotter than it should
so i replaced water pump and thermostat but since
then the thermostat wont open up thought maybe i
got a bum thermostat so went and got another but
its still not opening the pump is pumping but im
getting no pressure out of the upper hose making
me think the thermostats not opening up it keeps
over heating ive had to run it with out a thermostat
so i can get around town without it overheating any
suggestions i flushed the system and bled it but
still over heats
