my 1999 mazda 626 keeps over heating on me we have changed the radiator cap flushed the radiator put a new upper hose on it and put antifreeze in it.
i just took it for a test drive and now my temp gauge will start to go way up
towards the h then it would go back down to the middle then back up then back
check/replace the temp sender and wire...get the air out of the system....drill thermostate...
