On a 4.9L follow the upper radiator back to the engine. This should be the thermostat housing. The thermostat should be inside. On a 4.6L the thermostate is in the housing which is near the water pump drivebelts "on the coolant crossover housing". If this is not clean I recommend you buy the Haynes for your DeVille. See page 3-4, illustration 3.14.
locate the thermostate on the lower rad hose as it enters the engine block. Remove the 2 thermostate mounting bolts and remove the circular thermostate. Installation is the reverse of removal. Ensure you obtain a new gasket prior to installing the new thermostate.
They will not be identical but they might fit. The DeVille had minor changes to the interior and exterior in 97. 94 through 96 will work for sure, and 97 through 01 fit each other, then 02 through about 06 are the same but completely different from 01 and earlier.
yes but it depends on the with of the tire a good tire and wheel shop should know how wide you can go
