A trip in frost -42 - Toyota RAV4, 2.0 L, 1997

I had to go to Yekaterinburg yesterday in the morning, the frost was crushing - 42. It's warm in the cabin, but the suspension is not very comfortable in such frosts. Everything was stiff, the Amorths generally stood up with a stake. And on the way, it also grabbed the breather - squeezed out the dipstick and sprinkled everything with oil - it's a shame. Tell me who was washing the engine of soaps - problems arose later? The general conclusion - nefig in such frosts to rape the car.
