When is it necessary to do a deep cleaning?

How can you tell when your cooling system needs a deep clean? Starting with common problems such as abnormal water temperatures, buildup of impurities, and reduced efficiency, we'll share practical ways of making this determination, helping car owners and users to take timely action to maintain their cooling systems, avoid damage to equipment, and extend its useful life.

are all common manifestations of a cooling system in need of attention.

If the cooling system is not functioning, there are often clear "protest signals.For example, if the temperature gauge on the dashboard is always in the red zone, or if the air conditioner isn't cooling as well as it used to, then you should take note.If, for example, you find that the antifreeze is cloudy, or you can see rust or sediment in it, it's like having sand blocking up your water pipes. If you don't clean it out, it's going to cause problems sooner or later.

The water temperature abnormally rises.

If the water temperature shoots up in the first few minutes of driving, or if the warning light comes on, don't push your luck.This is probably because the cooling pipes have been clogged up with mineral deposits or other impurities, preventing the heat from being dissipated.This is especially true for older cars, whose radiators tend to accumulate rust. A thorough cleaning may well be able to lower the temperature.

The antifreeze has changed color or has impurities.

Normal antifreeze is clear and bright in color (such as green or pink).If the liquid is cloudy, black, or has particles settled on the bottom, the system may have accumulated a lot of filth.At this point, simple fluid replacement is no longer enough, and a thorough washout is necessary.

Under what conditions is it necessary to deep clean?

Some people may think that "if it works, it works," but in the following situations you really shouldn't put off replacing a part:

Failure to change the antifreeze regularly.

Antifreeze should be changed every two or three years.If you don't change it within this period, the preservative will lose its effectiveness, the metal parts will rust and the scale will accumulate.At this point, merely changing the fluid is not enough--the whole system has to be "deep-cleaned.

There are still problems with heat dissipation after maintenance.

For example, if you've just replaced the water pump or thermostat, but the water temperature is still too high, it could be that there are small pieces of debris or glue left in the pipes from the work. A normal flush won't get them out, so you need to use a special cleaner.

Some tips for preliminary self-examination.

You don't have to go to a repair shop. You can make a simple judgment yourself.

1. When the engine is cold, open the water tank (be careful! ) and shine a flashlight into it. If you can see white scale or rust on the sides, it's time to clean it.

2. Feel the temperature difference between the upper and lower water pipes. If the engine has heated up and the upper pipe is hot to the touch, but the lower pipe is still cool, the circulation may be inadequate, and further action may be necessary.

If you discover any of these problems, don't be in a hurry to buy a bottle of cleaner and pour it down the drain.If the cooling system is badly clogged, it may be necessary to take it apart and clean it. It's best to have a professional mechanic do it, to avoid the risk of damaging parts.
