welp they come on at whatever 212-222f or so? varies fans? are there more then one? yes you can get a manual fan switch off ebay plug n play and turn it on whenever, its the engine isn't going over 210 wy turn cooling fan on that's operating temp?

let it idle till temps climbs to no more than 215F or so, of fans dont come on ride it get air through it cool it back down..

in death valley when its 130ish fans never go off, faster you go the hotter it gets, brutal, spring, winter, fall

get yourself a lazer temp gauge,make sure all temps are jiving and sensors/stat are not failing whatever..

you want to gain access to the thermostat housing then then the temp sensor housing.. from cold fire her up and let idle as temp climbs read the thermo and tempo sensor housing tempos, compare with gauge..

then check that your thermo is opening at around 185 f ... then as temp increases pay attention to fan action and the temp sensor readings make sure its all jiving.. lazer sensors make this abreeze anymore, formulate your own curve for determining when the thermostat opens and allows water through, such as hand on hose whatever..

find your manual the cooling system diagram, note direction of coolant flow, so you want to inspect the hose downstream of thermostat right? familiarize yourself with the system.. wont hurt, real simple the bay has like an $11 lazer sensor works very well i have 2 and they are reliable
