Remove the cylinder head when the engine is cold. Usually the cylinder head is removed to replace the gasket. A defective cylinder head gasket can be recognized by one or more of the following:
- A) loss of engine power;
- b) coolant leak. Exhaust clouds are white when the engine is warm;
- V) oil leak;
- G) coolant getting into the engine oil. In this case, there is not a decrease, but an increase in the oil level. Gray engine oil, foam on dipstick (dipstick), liquid oil;
- d) engine oil getting into the coolant;
- e) the coolant boils strongly;
- and) poor compression in two cylinders located next to each other.
The cylinder head gasket has up to 5 holes depending on the thickness. The thickness of the gasket, in turn, depends on the size of the protrusion of the pistons. On cars with 2.1 liter engines, in particular XUD11BTE and XUD11ATE, starting from serial number 90999999, gaskets are installed with not 3, but with 5 marking holes (see illustration).
5.0v Cylinder head bolt tightening sequence
5.0g Cylinder Head Gasket
A - sealing gasket installed on engines of earlier years of manufacture, with 2-4 holes, depending on the thickness
H - sealing gasket installed on engines starting with serial number 90999999
C - holes (1-5), indicating the thickness of the gasket.
D- this hole is available on all gaskets, regardless of their thickness
5.0d Piston
H - 44.8 mm. Pistons of this size are installed on engines of earlier years of production
H - 44.95mm. Pistons of this size are equipped with engines starting with serial number 90999999
To measure piston protrusion, follow these steps:
1. Install the pointer type indicator on the support 1 as shown in the illustration.
2. Zero the indicator by setting its pointer to 0.
3. Turn the crankshaft of the engine and measure the protrusion D of the corresponding piston when it is at TDC (see illustration 5.1). Repeat this procedure for each piston.
5.1 Install the pointer type indicator on support 1
4. Add up the results, divide by four to get the average piston protrusion.
5. Select the cylinder head gasket of the desired thickness depending on the value of D (see table).
