van over heats unless ac ison
Do you have a leak? Did you replace the thermostat?
You have a fan issue. Not sure if you're van has 1 or 2 fans. If your van has 2 cooling fans when you turn your ac on it activates the ac fan which help cool the radiator. If you have only 1 fan then you probably have a tempature sensor gone bad. Which the sensor tells the fan OK I'm at 200-220 degrees it time to tell the ecm/pcm that the fan needs to turn on. I hope this helps you.
