JAC Ruifeng s7 second warranty project, how many kilometers does Ruifeng s7 have second warranty?

Generally speaking, the second warranty of Ruifeng S7 is 8500 kilometers. After that, it is best to have one warranty every 5000 kilometers, up to 7500 kilometers. Any more will seriously damage the engine. After 5000 kilometers, the friction coefficient will be higher as you go to the rear. Running 1000 kilometers without replacement is equivalent to After replacing it after 2,000 kilometers of wear and tear, it can still run without replacement for another 10,000 kilometers, but the wear will double again until it breaks down directly or burns oil after tens of thousands of kilometers.

JianghuaiThe items that need to be completed for the second warranty of Ruifeng S7 are the following:

1. Replace engine oil, oil filter, and clean air filter;

2. Check the liquid level and freezing point of the antifreeze, and clean the radiator surface;

3. Check the battery condition and horn lighting system;

4. Check whether there is oil leakage in the braking system and whether the friction plate thickness is within the specified thickness.

Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting or replacing certain parts of the car, also known as car maintenance.

Car maintenance mainly includes the maintenance scope of the engine system (engine), transmission system, air conditioning system, cooling system, fuel system, power steering system, etc.

The purpose of car maintenance is to keep the car clean and tidy and in normal technical condition, eliminate hidden dangers, prevent failures, slow down the deterioration process, and extend the service life.

A car is a very complex large machine. During operation, various mechanical components will inevitably wear and tear. Coupled with the influence of external human factors, environment and other factors, the loss of the car will be caused.
