Leaking Antifreeze on the Driver's Side of a 1997 Monte Carlo Z-34
- 1). Turn off your Monte Carlo and allow the engine to cool completely. Pop the hood and remove the radiator cap located on top of the passenger side of the radiator in the front of the engine compartment. Unscrew the oil filler cap and extension from the front valve cover and lift the plastic engine cover off the engine. Lay the engine cover aside
- 2). Add coolant dye to the radiator through the opening exposed when you removed the radiator cap. Add water to the radiator until the radiator is full. Then, start the engine. Allow it to run until the coolant is circulating through the engine (the upper hose will get hot to the touch) and then let the engine run for another 10 minutes.
- 3). Screw the cooling system pressure tester to the radiator in place of the radiator cap. Pressurize the system to 16 psi by pushing the knob on the end of the tester in and out. Look for traces of florescent green dye around the intake manifold on top of the engine, on the water pump at the front of the passenger-side of the engine, at rubber hose connections, and around the radiator seams on both sides of the radiator. The dye circulating in the system will make even a small leak easy to detect.
