What is the torque of connecting rod screw of Jetta engine?

The torque of connecting rod screw of Jetta engine is above150n m.

Generally speaking, it can reach the highest torque index when the engine speed is relatively low, which shows that the engine technology of this car is good and the strength is good. Some cars only reach the highest torque index at the speed of about 5000r/min, which shows that "strength" is not the strength of this car.

It can be said that the driving pleasure we pursue mainly comes from torque, which is the so-called "pushing back feeling". If the maximum torque of a car engine appears in the range of speed that we often use, then such a car can definitely bring you extraordinary driving pleasure. For family cars, the perfect engine maximum torque should appear at a very low speed, while the maximum power appears at a relatively high speed.

Tightening method of cylinder head screw:

1. First, screw it from the middle to both sides, the first time to 50% of the final torque, and then completely loosen it.

2. Then twist 50% from the middle to both sides.

3. Finally, just tighten the cylinder head screws in the middle and then on both sides. But don't screw it too tightly, otherwise the bolt will be stressed too much, which will not only cause the internal thread to slip, but even break directly. Therefore, everyone should determine the torque of the bolt before tightening.
