Does it matter if the car hasn’t been changed for ten years?How often to change car coolant

Under normal circumstances, the replacement cycle of vehicle coolant is 2 to 3 years or when the vehicle travels to 40,000 kilometers, it needs to be replaced once. The impact is very large. Because in this case, if the coolant is not replaced for a long time, the cooling effect inside will be reduced. However, once the cooling effect is reduced, it is impossible to ensure that the engine can maintain a normal temperature during use.

Therefore, the engine will be overheated. Once the engine is overheated, its performance will be greatly reduced, thereby reducing the service life of the engine, which is considered to shorten the service life of the engine. Secondly, if the vehicle has been driven for 10 years and the coolant has not been replaced during the period, then the coolant is actually deteriorating. More chemical deposits will be produced in the deteriorating coolant, which is not conducive to the circulation of the coolant. .

So in general, if the vehicle has been used continuously for 10 years without changing the coolant, it will have a significant impact on the vehicle itself. Therefore, it is recommended that the owner should replace the vehicle's coolant scientifically. After all, the coolant is the main source of heat dissipation for the vehicle. Source, if the vehicle does not have a heat dissipation system, then the performance of the vehicle will definitely be reduced step by step, and eventually the vehicle will be scrapped.

Therefore, the replacement time of the car coolant is as mentioned in the first paragraph. The replacement cycle is every 2 to 3 years or every 40,000 kilometers of the vehicle, but the specific situation depends on the actual use of the vehicle.
