1. First, remove the residual glue on the flange surface, and clean the flange surface with a special cleaner to restore the flange surface to a clean, smooth, and oil-free surface;
2. Then make an opening at the silicone mark with a diameter of 3mm, apply the silicone evenly on the flange surface, and the thickness of the sealing strip is 2-3mm to avoid excessive glue overflow;
3. Install within 5 minutes after sizing to prevent the silicone surface from drying out and affecting the assembly;
4. After assembly, use the bolts to tighten, and tighten the bolts in the order of tightening diagonally according to the tightening torque; after the silica gel is dried for 30 minutes, oil can be added.
The function of gasket maker
For the common but can not be ignored fault of oil sump oil leakage:
If the oil leakage is caused by cracks on the outer surface of the oil pan caused by the collision, a new oil pan needs to be replaced;
If it is caused by the uneven contact surface between the oil pan and the cylinder block, or the sealant between the oil pan and the cylinder block is damaged or insufficient, the oil pan needs to be removed and resealed.
Here I have to mention the engine sealant developed for the engine seal. If there is a problem with the engine seal, it basically means that the engine loses its tightness. What will happen?
◆ Engine power drop
◆ The engine burns oil
◆ Engine overheating
◆ Serious engine wear
◆ shortened engine life
◆ Engine scrapped
Although most of these situations are not directly caused by poor sealing, they are all caused by poor sealing. In other words, if you find that your car has poor power recently, blue smoke or black smoke or even white smoke from the exhaust, and the water temperature is overheated If the problem still occurs after the repair, then it is very likely that the cause is the relationship between the deterioration of the engine sealing.
The function of the engine sealant is to make up the gap between the flange surfaces. Due to the limitation of machining, the actual contact area between the two flange surfaces is only about 25%-35%. The use of silicone sealant can realize the two flange surfaces. 100% contact.
A good engine sealant has:
◆ Strong anti-aging ability;
◆ Non-corrosive and will not damage the screws and other parts on the engine;
◆ Prevent the "poisoning" failure of the oxygen sensor and the three-way catalytic system;
◆ High temperature resistance, oil resistance (high temperature resistance is easy to understand, oil resistance means that it can maintain the sealing even in gasoline immersion, so as to prevent the chain reaction after a certain part of the engine is damaged.)
The curing method is to absorb the moisture in the air for curing, gradually become a highly flexible elastomer, seal the flange surface, and absorb the vibration and displacement of the flange surface.
Standard application procedures should be followed when using engine sealant for oil sump sealing:
1. First, remove the residual glue on the flange surface, and clean the flange surface with a special cleaner to restore the flange surface to a clean, smooth, and oil-free surface;
2. Then make an opening at the silicone mark with a diameter of 3mm, apply the silicone evenly on the flange surface, and the thickness of the sealing strip is 2-3mm to avoid excessive glue overflow;
3. Install within 5 minutes after sizing to prevent the silicone surface from drying out and affecting the assembly;
4. After assembly, use the bolts to tighten, and tighten the bolts in the order of tightening diagonally according to the tightening torque; after the silica gel is dried for 30 minutes, oil can be added.
