I bought my van as is about 6 months ago , well about a month ago it got overheated & broke down. It was steaming ect. Well we got it home & ended up replacing the thermostat & it was just fine for awhile. Well it started overheating again so we find out the radiator fans weren't working so we replaced those as well. I was told it was still overheating. Any idea what to do next I can't really afford to take it to the shop atm. But we're down to 0 vehicles & need to get it working properly.
