OP, go to www.realoem.com and enter the last 7 characters of the carís VIN. Hit enter and bookmark the page. Scroll down to the engine section icon and click on it. Scroll down to the waterpump / thermostat link and click on it. Youíll find the bolts for the both the pump and the thermostat. Youíll be able to see the specs for each bolt. Go to Home Depot and buy what you need.
