Ok so you guys have helped me out alot and now for the final question.
The weather is -3 degrees celcius outside with snow on the ground. Snow has stopped and I changed the thermostat and flushed out the rad the other day. The rad is sitting empty as we type and I wanna fill it back up to test out the thermostat. Would the temp outside be a problem with this and also what is the best way to get all the air out of the rad without driving it? The blazer is sitting on stands because there is more work I want to do underneath so how would someone go about filling and burping the rad with dexcool?
