Chevrolet G20 Temperature Problem. Just replaced the belt as the old one broke and caused the temp to rocket. Now the temp gauge goes to normal then rises to overheat then falls to normal and up again?

It's time to replace the thermostat. The obvious would be lack of coolant----but assuming you have checked that the possibility exists that you have a blown head gasket ---I know that you have a Chevy full size van (G 20) but know nothing about the year or mileage --that being said when the belt broke you may of severly overheated the engine---not good for any vehicle but very bad for old high milage motors
