David T. Gould presents: The continuing saga of the thermostat replacement on a 2003 Pontiac Aztec 3.4 liter motor. Issue: Overheating after initial replacement. Thermostat delayed opening. (Saw this water bottle trick on another YouTube posted video and thought I would try it out) It worked. PLEASE DO NOT ATTEMPT. IF YOU MUST... BE SURE YOU HAVE PROPER PROTECTIVE EQUIPMENT TO AVOID HOT FLUIDS / SCOLDING. I am NOT a mechanic... I am mechanical. Be sure to take this video and it's contents as informational, not advise. Professional repair is ALWAYS the recommended option. Enjoy the show!

Note(s): I mention water multiple times, the coolant I am referring to is Dex-Cool anti-freeze recommended for these motors. You will see the orange color.
