HELP!!!!!!!!, one of those overheating problems Options

[Theshanon]

Sorry guys i tried to search but nothing came up!!

ANYWAYS, so my car is infact over heating.

First week i noticed this- K!!! so about a week ago my temp gauge started acting up....it would rise..then when i turn my heater on it would drop. Couple days later my heater would no longer work, so i checked my coolant and barley had anything left so i topped it up. Everything seemed fine for a bit, then a day or two after my temp gauge reach above 'H' and i pulled over and it sounded like my head was boiling a nice pot of soup. I waited a bit and quickly released the rad cap. It steemed for a bit (obviously) and i toped it off with coolant and it ran fine for a day or two. So today on my way to work i ended on heading back home on a flat bed. My temp gauge stayed at above 'H', no warm air....i topped it of with coolant, and i donno where it goes :| its hard for me to tell if theres a leak...and i hope its not my head gasket?

I always try the super simple stuff first - you already tackled the thermostat, so that's taken care of.

How old is your radiator cap? If it's old and doesn't pressurize, you'll overheat. Get a new cap, run the car a few minutes (literally, like 2 or 3 minutes should do it) w/the cap off (to get all the air out of the system), shut it off and put the new cap on. It's a four-dollar fix that won't break the bank if it's the wrong fix.
