I have a 85 chevy blazer....new transmission, new radiator and oil filter. That's all I know. Oil, just checked, just put antifreeze and water in reserve, but a white cloud of smoke just started coming from underneath the truck when I stop or slow down. (looks like its coming from behind somewhere)! Also the Gage says its getting hot really fast! Your help is much appreciated!! Thanks a bunch
*** Also looks like its leaking something in front!

The heater does work I used yesterday, Is it possible to do it yourself or is it better to just take it in?
