Review on ATD Tools 3310 Thermostat Wrench by Ricardo Stewart

Worse than USELESS for 2005 Buick Rendezvous. Don't buy that for this car. Hours will pass, damage will occur, and the thermostat will still be cozy in its eternal home. (Hint: Remove the throttle body, heater inlet/outlet pipe, attached hoses, air filter and electrical connections. It's ten times faster than trying to get that torture wrench to work.)
