2002 Cadillac Seville SLS Q&A
2002 Cadillac Seville SLS Question: Where is the Thermostat located and how can I change it please.
It is under the cover that the upper radiator hose attaches to with a clamp. The thermostat will go in the same position the old one came out. Then it all needs to be cleaned and re-sealed and reconnected with no leaks. - ProfessorG
