Classification of oil cooler and troubleshooting steps

Oil Cooler This is a device that accelerates the heat dissipation of lubricating oil and keeps it at a lower temperature. It keeps the engine oil temperature within the normal operating range and ensures the oil has the proper viscosity for lubricating engine parts. Below, the editor of Uni-President Engine Oil 7 Series will share with you the types of oil coolers and the replacement steps.

First of all, currently common oil coolers can be divided into: engine oil cooler, transmission oil cooler, retarder oil cooler, exhaust gas recirculation cooler, radiator air cooler.

The function of the engine oil cooler is to cool the engine oil and keep the oil at a reasonable temperature between 90-120 degrees for a long time and maintain normal viscosity; usually its installation position is in the cylinder of the engine, and it is installed with the casing. Install as a whole.

The transmission oil cooler is installed in the lower tank of the engine radiator or outside the transmission case. If the cooler is air-cooled, it is installed on the front side of the radiator.

Retarder oil coolers are generally installed outside the gearbox, and are mostly shell-and-tube or water-oil composite products.

The exhaust gas recirculation cooler is a device used to cool some of the exhaust gas that returns to the engine cylinder. The purpose is to reduce the content of nitrogen oxides in the automobile exhaust.
The heat dissipation cooler module is a device that can cool multiple objects or some objects such as cooling water, lubricating oil, compressed air, etc. at the same time. The cooling module adopts a highly integrated design idea and has full functions, small size, and intelligence. Features.

The air cooler, also known as the intercooler, is a device used to cool the high-temperature and high-pressure air after the engine is supercharged. Through the cooling of the intercooler, the temperature of the supercharged air can be reduced, thereby increasing the density of the air, so that the engine can achieve ideal power and reduce fuel consumption and emissions.

With the understanding of the unified engine oil 7 series package, the material of the oil cooler core is usually required to have strong corrosion resistance and heat dissipation. Currently, it is divided into two types: copper and stainless steel. Of course, the copper one has Strong heat dissipation and corrosion resistance, stainless steel is second. The heat dissipation of stainless steel is not as good as copper materials, but the corrosion resistance is stronger than copper materials.

The editor of Tongyi Motor Oil 7 Series shares the installation steps of the cooler
First, insert the new D-ring into the D-ring installation groove of the oil cooler. The flat part of the D-ring needs to be installed toward the side of the oil cooler.
Secondly, use a scraper to remove the dirt on the joint surface of the cooler and the cylinder block, and then apply the sealant on the cooler. The application must be even and without breaks. After applying the sealant and leaving it for 20 minutes, insert the positioning stud bolts into the mounting threaded holes of the cylinder block, and then install the cooler.

In addition, after temporarily tightening the bolts, remove the positioning stud bolts and tighten the bolts again. (Needs to be tightened together with the alternator ground). Tighten to torque , then install the drain plug.
