There should be a dome and under that dome is the t-stat. Just make sure to clean off the old gasket before re-installing and burp the cooling system. Any air trapped may cause cavitation, damage to water pump, and overheating. Check for leaks when you are done. Strongly recommend getting a repair manual for instructions on burping the cooling system.
