What is the use of motorcycle oil radiator?

Understand the knowledge of cars, so that every owner can maintain them well and not waste money. Colu is a classic car that saved GM. Its beautiful design, especially wine red, captured the hearts of many young people at that time. Network 1.6AT Cruze is a car that scares used car dealers. Brother Pang thinks that manual Cruze can still buy used cars, but the small problem is that it can be repaired at a little money. High fuel consumption and poor power, you should be mentally prepared.

Information: Classic Cruze 1.6L manual gearbox, traveling more than 90,000 kilometers.

Vehicle failure: it is preliminarily judged that the oil radiator connector is leaking antifreeze.

Function of the oil radiator: The function of the oil radiator is to forcibly cool the oil, so as to prevent the increase of oil consumption caused by excessive oil temperature and prevent the oil from oxidation and deterioration.

Principle of oil radiator: the oil cooler is placed in the cooling water channel, and the temperature of lubricating oil is controlled by the temperature of cooling water. When the temperature of lubricating oil is high, use cooling water for cooling. When the engine starts, it absorbs heat from the cooling water, which quickly increases the temperature of the lubricating oil.

Maintenance steps:

1. Remove the exhaust pipe heat shield and pull out the front oxygen sensor.

2. The exhaust manifold is commonly known as the banana fan, and you can see the oil radiator when you remove it.

3. The two ends of the oil radiator are respectively connected with a thermostat, a water pump and an oil pipeline. This is the removed waterway pipeline, and the connected rubber sealing ring has been seriously corroded and aged.

3. A complete set of gaskets for oil radiator, a set of dozens of ocean.

This time, Brother Pang found that there was no oil leakage and antifreeze around the radiator, and no oil foam was found in the antifreeze pot. The radiator must be good. The radiator has a simple structure, and the oil path and the water path are insulated from each other by gaskets.

5. All joint sealing rings should be replaced with new ones.

Note that when replacing and installing the sealing ring, if you are not completely sure, you can apply sealant appropriately. But don't overdo it. Excessive sealant may flow into the waterway after installation and extrusion, resulting in poor heat dissipation of the engine.

Summary: If you find oil foam in Cruze kettle, please check the oil radiator first. You can try replacing the sealing ring first. If the radiator itself is corroded, then the waterway and oil circuit of the radiator are connected. When the engine is working, the oil is forced into the water channel because of the high oil pressure, which is why there is oil in the kettle.
