What are the common causes of fuel injector copper sleeve damage? Let's discuss it together!
There is no need for antifreeze. After the lack of antifreeze, tap water is often used instead. It seems that there is no problem in the short term, but after a long time, the copper sleeve and seal ring of the injector will be damaged.
The antifreeze has been used all the time, but the copper sleeve is still broken. Generally speaking, the fake antifreeze is purchased when replacing the antifreeze. The fake antifreeze, like water, will corrode the copper sleeve and sealing ring, and over time, the above faults will also occur.
When we find that there is no reason for the lack of coolant, and there is no leakage outside, we should check it in time. It is very simple to judge whether the copper sleeve of the fuel injector is damaged. First of all, see whether the oil in the fuel tank becomes turbid. If you can't see clearly in the fuel tank, you can check the water collecting cup of the filter, where you can see the antifreeze directly. If you find the antifreeze inside, you can basically judge that your fuel injector copper sleeve is damaged.
Generally speaking, the copper sleeve of fuel injector needs to be replaced by lifting the cylinder head. However, experts are in the civil society. Many experts specializing in electronically controlled diesel engines have self-made tools that can be replaced without lifting the cylinder head. The copper sleeve should be maintained regularly to avoid damage.
