The maintenance and maintenance of car intercooler mainly includes the following aspects :
Regular Inspection and cleaning : The intercooler can build up debris or create clogs inside after a period of use. It is recommended to inspect and clean the intercooler every three months to ensure that it is working properly 1. There are two cleaning methods: one is to use high pressure water gun to clean the surface dirt; The second is to disassemble the intercooler and immerse it in a specific solution for a thorough cleaning 2.
Replace the water and grease in the intercooler : The water quality in the intercooler should be soft, hard water can cause scaling and corrosion of the intercooler, reducing its service life. It is recommended to replace the water and grease in the intercooler regularly, and to clean the pipes and intercooler 1 before replacing them.
Protection against corrosion : Intercoolers are made of metal, which may develop corrosion due to poor water quality or humid climate after long use. Preservatives can be added to extend the life of the intercooler 1.
External and internal cleaning : Since the intercooler is installed in the front of the vehicle, there may be debris such as sludge and leaves blocking the channel of the heat sink, affecting the heat dissipating effect. Therefore, regular external cleaning is required. At the same time, the internal pipes of the intercooler may adhere to sludge and gum, affecting the cooling heat exchange capacity, and regular internal cleaning and inspection 3 is also required.
The role and importance of intercooler :
Reduce intake temperature : The main role of the intercooler is to reduce the intake temperature of the engine, eliminating the adverse effects of air heating after pressurization, thus improving the engine's charging efficiency and power output 34.
Improved engine performance : By lowering intake air temperature, intercoolers can significantly enhance engine power performance, reduce fuel consumption, prevent engine deflagrations, and improve altitude adaptation 5.
Environmental protection : Uncooled pressurized air entering the combustion chamber can lead to excessive combustion temperature of the engine, increasing the risk of knock and NOx content in the exhaust gas. Using an intercooler can effectively reduce these problems and protect the environment!
External cleaning
Use a water gun with low pressure : Hold the water gun perpendicular to the plane of the intercooler and rinse slowly from top to bottom or bottom to avoid slanting to prevent damage to the intercooler.
Alkaline cleaning : When the cooler has oil stains on its exterior, soak it in an alkaline solution and then remove the oil stains with a brush.
Internal cleaning
Use an aqueous solution of 2% soda ash : Inject an aqueous solution of 2% soda ash at 70-80 ° C into the intercooler and wait 15 minutes to check for leaks. If there is leakage, perform welding repair; If there is no leakage, gently shake the intercooler, pour out the sewage, and again inject a clean 2% aqueous soda solution until clean.
Raise the water temperature : Finally, it can be washed with 80-90 ° C hot water until the discharged water is clean.
Notes
Avoid damaging the intercooler by using a high-pressure water gun or using direct water to flush vigorously.
Use the appropriate cleaning agent and avoid overly strong cleaning agents that can cause damage to the intercooler.
Regular Inspection and maintenance : The intercooler should be cleaned and inspected annually or when the engine is overhauled to ensure that it is working properly.
