Relatively easy to do. First, get a replacement thermostat at auto parts store (make sure they double check the stock #; they all look similar and you want the right one the 1st time). Get some coolant too, if there's none left from the flush. Follow the radiator hose (large black hose on top of radiator) from the rad. to the engine block; where the hose connects to the block is where the thermo. is...usually 2 bolts to hold it in place. Be sure to look at instructions because the thermo. has to be installed the correct way facing up. Swap thermo, replace hose, add coolant if needed & good to go
