Question about 1986 Toyota 4Runner
The thermostat is located at the end of the upper radiator hose. Were the hose connects to the top of the engine on the passenger side of the valve cover on the engine. I believe the housing takes a 12mm socket. Don't for get to get a new gasket for the thermostat housing, how thermostats come with the gasket. I also recommend changing your radiator pressure cap 13psi.

Follow the top radiator hose from the radiator to where it attaches onto the engine. The thermostat is inside the housing that the hose attaches to. Remove the radiator hose at thermostat housing. Remove the housing. There are usually two bolts. The thermostat is inside. Scrape off all old gasket material and clean the housing. Install new thermostat and gasket. Be sure not to overtighten the bolts on the housing. The housing is usually cast metal and is easily cracked or broken if the bolts are overtightened. Hope this helps and best wishes.
