Please run down this guide and report back.

No it is not boiling over. It is just the gauge. I've replaced the thermostat, and water pump. What can I do?

Test the CTS

How do I do that?

Use a digital volt/ohmmeter-Why don't you just bring her in

I don't have the extra cash to spend. I'm a low income ****** of 2, trying to make it. I bought the Coolant/Temperature sensor today to put on it, so maybe this will fix it! :)

Are the cooling fans coming on?

yes, they are comming on.

Did you replace the CTS -if it continues have it block and pressure tested-Could be the temperature gauge is out of calibration

1997 Chevorlet Venture leaks antifreeze in back of motor and overheats easily.

You need to find the leak and fix it, I can't tell where it is without looking?

As far as overheating does it boil-over? Check the thermostat-- radiator fan--coolant flow-- check for combustion gases in the coolant.

van over heat then when gauges get to red it goes back down. checked for leakes but there are none. oil is fine

check the thermostat as that may have been the issue but now i would also suspect a head gasket from the overheating. have a leak down test done to be sure
