What are the common causes of damage to the injector copper sleeve? Let's discuss it together!
Antifreeze is not needed. When the antifreeze is missing, tap water is often used instead. This seems to be no problem in the short term, but after a long time it will cause damage to the injector copper sleeve and sealing ring.
The antifreeze is always used, but the copper sleeve is still broken. Generally speaking, the fake antifreeze is bought when the antifreeze is replaced. The fake antifreeze, like water, will also affect the copper sleeve and sealing ring. Corrosion occurs, and the above failures will occur over time.
When we find that the coolant is lacking for no reason, and there is no leakage from the outside, we should check it in time. It is very simple to judge whether the copper sleeve of the fuel injector is damaged. First, check whether the oil in the fuel tank becomes turbid. If you can’t see clearly in the fuel tank, you can check the water collection cup of the filter, where you can see the antifreeze directly. If there is antifreeze, it can basically be determined that the copper sleeve of your injector is damaged.
Generally speaking, the injector copper sleeve needs to be replaced by lifting the cylinder head down, but the master is in the private sector, and many experts who specialize in electronically controlled diesel engines have homemade tools that can be replaced without lifting the cylinder head. The copper sleeve must be regularly maintained to avoid damage.
