Don't be fooled into thinking that all thermostats from 2004-2010 are the same. Starting in 2009 GM changed the size of the thermostat on all Corvettes. It is only by a minimal size, but using the older style thermostat will not seal in the water pump and will cause a leak. Zip offers this Motorad (OEM) thermostat in 160 degrees. This is a drop in replacement 160 degree thermostat that is the correct size and fits all 2009-2010+ Corvettes.
