Motorcycles emitting white smoke is caused by the engine burning oil. Here are specific explanations about oil burning: 1. Hazards: Long-term oil burning will reduce engine oil volume, deteriorate the lubrication system, increase wear, and decrease cooling effectiveness, making the engine prone to overheating. The cleaning effect of oil on the engine will also worsen. 2. Inspection: Regularly check the engine oil level. After the vehicle has been stopped for a while, pull out the oil dipstick, wipe it clean with a tissue, reinsert it, then pull it out again. The level should be between MIN and MAX to be normal; after starting, observe whether the exhaust emits blue smoke and check if there is any blue oil residue in the exhaust pipe.

Where is the engine radiator located in a van?

The radiator of a van is located at the front of the vehicle. The radiator must be placed at the front to utilize airflow for cooling. Here is some related information: 1. Automobiles use water-cooled engines, which rely on coolant circulating inside the engine to dissipate heat. The coolant also needs to be cooled, and the radiator is responsible for cooling the coolant. 2. The coolant has two circulation paths inside the engine: a major cycle and a minor cycle. When the engine is first started and has not yet reached normal operating temperature, the coolant circulates in the minor cycle, which helps the engine warm up quickly. During the minor cycle, the coolant does not pass through the radiator. Once the engine reaches normal operating temperature, the coolant begins the major cycle. During the major cycle, the coolant passes through the radiator, ensuring the coolant temperature remains within a reasonable range. 3. The coolant needs to be replaced regularly; otherwise, its boiling point may decrease and freezing point may rise. Generally, the coolant should be replaced every two years.
