Incorrect installation may result in damage to the cylinder head.

After removing the cylinder head, place the block on a wooden surface.

Check that the surface between the head of the block and the block is not damaged.

INSTALLATION

Rinse all parts before installation,

Always use a new cylinder head gasket and exhaust manifold gasket.

Always use new bolts capturing the cylinder head.

The cylinder head gasket is metal, be careful not to damage it.

Turn the crankshaft to set the piston of the first cylinder to the TDC position.

 Removing and installing the cylinder head of the G6EA engine

After installing the cylinder block gasket, install the block head.

When installing, specify the dimensions of the left and right cylinder head gaskets.

 Removing and installing the cylinder head of the G6EA engine

Tighten the cylinder head bolts with washer in the following order:

  • - When assembling the washer, the marked surface must be at the top.
  • - When installing the bolts, apply engine oil to the threads of the bolts and the surface of the washers. Tightening torque: 24.5 Nm

 Removing and installing the cylinder head of the G6EA engine

Using the special tool (09221-4А000), tighten the bolts using the angle tightening method.

Left camshaft chain mark

Install the phase shifter assembly and timing chain sprocket with locating pin in the phase shifter mounted on the intake camshaft

Make sure the pin is not in the oil supply hole. Tightening torque: 66.7 - 78.5 Nm.

After installing the phase shifter bolts, turn the phase shifter assembly counterclockwise by hand, place the pin in the appropriate position.

Fix the hex area of the camshaft with a vise, then tighten the bolts. Do not fix the phase shifter or sprocket

Install the camshaft onto the cylinder head assembly.

- Align the marks on the inlet and outlet sprocket of the camshaft chain and timing chain.

Right camshaft chain mark

To assemble, both marks must be at the top

Install the intake and exhaust camshafts on the cylinder head, matching the marks.

 Removing and installing the cylinder head of the G6EA engine

Install the timing chain tensioner.

  • - Install the pin by pressing the chain tensioner.
  • - Install the tensioner (A) on the cylinder head.
  • - Remove the pin from the tensioner after installation.

 Removing and installing the cylinder head of the G6EA engine

Install the camshaft bearing caps. Tightening torque: bolt (A: 6x38): 10.8 - 12.7 Nm, bolt (6: 8x38): 20.6 - 22.5 Nm.

A - left / right; B - inlet / outlet; С - cover number

When installing the bearing caps, check for the marks as shown in the figure and install them in the correct position.

When installing the bearing caps, rotate the crankshaft to place the piston in the middle of the block as there may be a collision between the valve and the piston.

 Removing and installing the cylinder head of the G6EA engine

Using the special tool (09214-21000), install the camshaft oil seal.

Apply engine oil before installation

The camshaft cover must be firmly attached to the cylinder head assembly.

Do not create an off-center load.

Install the camshaft sprocket.

  • - hold the hex area of the camshaft in a vise and screw in the bolts. Tightening torque: 88.3-107.9 Nm
  • - In case of replacing the camshaft with a new one, check the valve clearance, then install the tappet.

To prevent check the collision of the valve and the piston, rotate the crankshaft sprocket 3 turns from TDC of the first cylinder, then measure the valve clearance.

- Remove oil, dust and sealant from the cylinder surface before assembling the cylinder head cover.

Reassemble the cylinder head cover five minutes after applying sealant to the camshaft cover.

Tighten the cylinder head bolts in the correct order (A). Tightening torque: 7.8 - 9.8 Nm

- Do not start the engine within 30 minutes after installing the cylinder head cover.

Do not install an old cylinder head gasket.

Install the timing belt.

Align marks on left and right camshaft sprockets.

To prevent the valve and piston from colliding, rotate the crankshaft sprocket 3 turns from TDC of the first cylinder, then align the marks on the sprockets.

After aligning the marks on the camshaft sprockets, rotate the crankshaft sprocket 3 turns clockwise and align the crankshaft sprocket mark to set the No. 1 cylinder piston to TDC.
