I have a 1995 mercury villager and it is running hot. I put a thermostat on and opened the radiater plug and drained the coolant. Added more and i got pressure to my hoses then no pressure and then all the coolant backed up from the radiater into the resovoir and still over heating. What do anyone think?

u need to PRIME TH COOLING-SYST, STEPS ARE very important,,theres th highest point of the
ENGINE,on top of the intake-plenum,big-black-hex-nut and on top is a small-bolt,u need to open
that bolt & or take it off, then SQUEEZE THE TOP RADIAT--HOSE,,and keep squeezing until
COOLANT STARTS coming-out from the hole on TOP-OF,that small-bolt was removed,also
run the HEATER-ON-HIGH,also while ENGINE is ON (RUNNING),,KEEP eye on coolnt-TEMP,
DONT let it get into the RED!!, also make sure FANS-CLICK ON!!! u need to PRIME TH COOLING-SYST, STEPS ARE very important,,theres th highest point of the ENGINE,on top of the intake-plenum,big-black-hex-nut and on top is a small-bolt,u need to open that bolt & or take it off, then SQUEEZE THE TOP RADIAT--HOSE,,and keep squeezing until COOLANT STARTS coming-out from the hole on TOP-OF,that small-bolt was removed,also run the HEATER-ON-HIGH,also while ENGINE is ON (RUNNING),,KEEP eye on coolnt-TEMP, DONT let it get into the RED!!, also make sure FANS-CLICK ON!!!
