When the vehicle is running, the water is returned to the water from the water tank of the expansion tank. Gasket damaged parts is a string of hole position. String hole cylinder gasket is connected with the cylinder body and cylinder gasket damage into the waterway, cause the cooling water from the water hole of the expansion tank to return.
After the failure of the water is found, oil can be used to determine the specific location. Baotou North Benz parts release by cylinder injection pump high-pressure tubing connector, fuel door test, cylinder pad without damage, cut off oil, in addition to the engine speed down, return water unchanged; while the cylinder gasket destroyed the cylinder, oil break, return less water, a fuel door, back to the water momentum increase, thus can determine the damaged cylinder gasket. After the cylinder gasket is damaged, the water tank is damaged, the water tank is short of water, and the engine is overheated.
Occurred in the northern part of the Mercedes Benz Baotou cylinder gasket failure should be promptly repaired, 10 million can not continue to operate in order to prevent the northern part of the Mercedes Benz engine parts of Baotou vicious failure. After the cylinder gasket is damaged, repair vehicles should be suspended, regardless of seasons, shall release the cooling fluid, the piston and the cylinder to prevent corrosion and other failures. Replace the cylinder head gasket, cylinder head and cylinder body should pay attention to the plane should not have impurities, and according to the specified tightening torque. The cylinder head bolt tightening torque: auxiliary bolt tightening torque for cylinder head: 100Nm+90 degrees 200Nm+90 degrees
