i planned to replace the standard d16 sohc vtec thermostat (88 degree celcius) to spoon thermostat (71 degree celcius)..

my concern is:

1-is it any good to use the spoon thermostat to enable the fan radiator to function early than before

2-do i have to replace the fan switch as well?if yes,does 78 degree celcius fan switch ok?

 

Is your car overheating? There is no reason to put in a lower temp t-stat. There is no reason to run the spoon thermostat.

 

yes..i notice that my thermostat only opens at 93celcius..by right that thermostat should open at 86celcius...i have replaced the original thermostat and the fan switch but same problem remains..coolant are good..fan also ok..but it spins late..

 

Is there air in the coolant system? How are you telling the temp?

 

i think it dosen't worth it for a street car. I would put this on a intensive race car.
