Got my Qoute from shop, they say its a domino effect of problems and want to change my water pump, thermostat and a flush. Total cost after tax is $757!! $245 for water pump which I dont think is the issue, $201 for the flush and $95 for thermostat change and the initial $85 to have tech take a look at it... price seems outragiously high to me. I have had zero issues with car since I bought it in 2006, should I give the go ahead to to the thermostat and flush and say leave water pump alone? knocks $250+tax off total.
