Hello everyone

Have you encountered the problem that the heater does not heat the engine (om651) during preheating.

Is it possible to customize it so that the heater heats up the engine during preheating?
I've heard that the cooling system includes a three-way valve so-called comfort valve. Eber controls it.

Do you have any suggestions on how to get the engine warm up.

thank you for
your replies
