Hello,

Does anybody have experience with a heat exchanger on a 912?

Translation german to english:

Four-way water thermostat for regulating the coolant temperature with built-in heat exchanger. Significantly shortens the warm-up phase

of the engine, as the cold oil is heated by the cooling water. Saves the oil cooler with hoses and enables a balanced one
Heat balance even under very unfavorable circumstances, such as very high altitude or in winter. Suitable for 80HP and 100HP engines. Whereby the
The flow to the water cooler must work well with the 100PS. Since no additional hoses are necessary for the water return,
a particularly light, compact and reliable assembly is created. The mean temperature difference between water and engine oil is approx. 10 ° C.
This perfectly sets the optimal temperature window for the cooling water with approx. 80 ° to 90 ° C and the engine oil with approx. 90 ° to 100 ° C.
Saves around 0.8kg compared to the previous versions with separate thermostats, T-pieces, heat exchangers and hoses with clamps.
Compared to the classic solution with oil cooler, oil thermostat and hoses, up to 1.8 kg of weight is saved.
