Im at 84000 miles am i due for any regular maintainace such as fluid flush or regualar problems at this milage such as water pump or hose replacement. i believe my overflow for radiator coolant is low or empty but wanted to check while the car cools off so i can open the cap to see. cant find a leak visable but do smell fluid burning from time to time when it gets hot. could it be a bad cap?
Rather then guessing take it an have it checked ! Most all qualified repair shops have a tool that pressure test's the cap . Know for sure Plus they can pressure test the cooling system .

dont get rid of the dex cool. there made just for gm's and is better than the green. and the water pump should be on the back side of the motor half way down

YOU NEED TO REPLACE THE UPPER INTAKE MANIFOLD. ALSO, YOU WILL NEED TO REPLACE THE LOWER INTAKE MANIFOLD GASKETS. THIS IS A MANUFACTURING FLAW. THE PLASTIC INTAKE CRACKS CAUSING AN INTERNAL COOLANT LEAK. YOU CAN RESEARCH THIS ON LINE.

Are your cooling fans working? that will definately be a problem if not working. if they are working shut car off and feel the radiator is it the same temp all over or is it hot in only top or one smaller area. if you do not have same temp feeling on all of radiator your radiator may be plugged.
