over heated once then i drove on it more tried blue-devil and it didnto help and it needs new head gaskets which cost 2500 with shop labor to get the car running again it would be faster and easier and better idea to put a 50k crate motor in from japan for 1200 so i sold the car for $400 but i bought it for $900 so no biggy
i replaced the freeze plugs because that's what i was told needed to be fixed but it still.runs hot and leaks my batteries dies..could you what really wrong with it
Radiator leaking out of vertical crack on plastic side area, on passenger side. Plan to have a shop replace radiator, quotes ranging $485-545.
It dumped a large amount of antifreeze when I left work. The engine over heated. I had some in the car. I filled it up and went home, with no more problems. Home was another 15 miles.
I replaced the upper and lower radiator hoses,along with the pump a shorter hose and the thermostat.
It hasn't dumped any water since. I still don't know what happened.
Its been leaking slowly ever since.

Now my fans don't run. I replaced the temperature sensor. It didn't help.
Replaced the radiator and corrected the problem. I attempted to seal the crack in the side of the radiator, but it wouldn't hold.
