Very Very simple job. follow the bottom rad hose up to the engine. Thermostat is behind the water neck the hose hooks to. 2 bolts hold it on and there is 1 bolt that grounds wires to it. Is it overheating? These are famous for Headgasket issues (there is a Honda Product Update on the gasket itself) so.... if its been hot it may be too late :/ Good luck bro.
