The invention relates to the field of engines, in particular to an adjustable cooling system of an engine. The system comprises a cooling main circulating pipeline. The cooling main circulating pipeline comprises a main path thermostat, an engine radiator, a main path water pump, a machine oil cooler, an engine cylinder body and a cylinder cover, which are communicated in sequence; a cooling circulating branch is arranged on the main circulating pipeline; one end of the cooling circulating branch is connected with the main path thermostat, and the other end of the cooling circulating branch is connected with one end of a water outlet of the engine radiator; and the main path thermostat can distribute the flows of cooling water in the cooling main circulating pipeline and the cooling circulating branch in real time according to the temperature of the cooling water. The adjustable cooling system can reasonably distribute the cooling water to precisely perform the real-time heat management for a whole vehicle, and can realize quick vehicle heating in a cold state of the engine when the engine reaches the normal working temperature as quickly as possible, so that the mechanical efficiency of the engine is improved, and the purposes of energy conservation and emission reduction are achieved.
