89 degree thermostat for lower cooling water temperature / engine temperature and more efficient combustion
The original thermostat opens at 95 degrees.
To further improve engine cooling, we recommend adjusting the fan control in addition to the thermostat.
Without adjustment, the coolant temperature drops while driving due to the airstream, but it drops significantly less when stationary and driving slowly.
By adjusting the fan control, the switch-on temperatures of the electric fans are lowered so that the cooling water temperature remains permanently low even when driving slowly and when stationary.
The adjustment of the fan control is possible, for example, with the Diablosport Trinity and inTune possible.
Alternatively, we can also program the engine control unit in-house without these devices, which is significantly cheaper.
We can also adjust the tolerance threshold for error code P0128 if it is set.
