Timing belt was replaced 20,0000 miles ago. Was charged $800.00 for water pump and thermostat replacement at a Chrysler/Chevrolet dealership. Had been quoted a $500 labor charge just before Christmas 2012. Went back April 2013 after 9am monday morn. They kept car 5 days and then had the nerve to tack on another $9.00 after check had already been written.Had asked for total w/taxes up front before saying do the job. Thanks for your answer.
