Carter forklift 980l warm air is not hot.

The engine is short of coolant. Forklift car air conditioning is different from household air conditioning. The warm air of the car air conditioner circulates in the engine by using the engine coolant, and is connected to the warm air box, and then blown into the car by the blower. If the engine lacks coolant, it will not be able to blow warm air, and it will also cause engine damage, so it should be replenished in time.
