1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
2. Turn the ignition switch to the OFF position.
3. Disconnect the negative battery cable.
4. Place the lock carrier into the service position.
5. Remove or disconnect the following:
* Accessory drive belts
* Engine covers
* Timing belt upper cover
6. Turn the crankshaft, in the direction of rotation (clockwise), until the No. 1 cylinder is at Top Dead Center (TDC).
7. Remove or disconnect the following:
* Timing belt tensioner by loosening it using Torx® wrench T45
* Belt from the camshaft gear by pushing the tensioner downward
* Torx® bolt and swing the tensioner assembly bracket forward
* Valve cover
* Cam gear retaining bolt by loosening it using retainer tool 3036
* Camshaft gear
* Camshaft Position (CMP) housing sensor and shutter wheel
* Hydraulic chain tensioner by securing it with bracket tensioner tool 3366Fig. 2: Do not overtighten the chain tensioner tool 3366, it can be damaged â 1.8L
8. Verify that the camshafts are at TDC for the No. 1 cylinder. Both camshaft markings must align with arrows on the bearing caps.
9. Clean the drive chain and the cam chain gears opposite both arrows on the bearing caps. Matchmark the installed position using paint.
NOTE: The distance between the 2 arrows/paint marks is equivalent to 16 drive chain rollers and the notch on the exhaust camshaft is slightly offset inward toward the drive chain roller.

10. Remove or disconnect the following:
* Bearing caps No. 3 and 5 from the intake and exhaust camshafts
* Double bearing cap
* Both bearing caps from the chain gears on the intake and exhaust camshafts
* Hydraulic chain tensioner retaining bolts
* Intake and exhaust manifold bearing caps No. 2 and 4 by loosening them in an alternating and diagonal sequence
* Camshafts with the hydraulic chain tensioner
To install:
Fig. 5: To ensure a proper seal, be sure to apply sealant to the hatched area â 1.8L
11. Replace the rubber/metal chain tensioner gasket and apply sealant to the hatched area, as shown.
12. Install or connect the following:
* Drive chain on the camshaft
NOTE: If installing the old chain, align the paint marks with the camshaft marks. If installing a new chain, the distance between the notches A and B on the camshafts must equal the distance between 16 drive chain rollers.
* Hydraulic chain tensioner by sliding it between the drive chain
* Camshafts with the chain tensioner lubricated with engine oil into the cylinder head
NOTE: When installing the bearing caps, verify the markings on the caps are readable from the intake side of the cylinder head.
* Intake and exhaust camshafts bearing caps No. 2 and 4. Tighten them in an alternating diagonal sequence to 84 inch lbs. (10 Nm).
* Both the intake and exhaust camshafts bearing caps on the chain sprockets. Tighten the bolts to 84 inch lbs. (10 Nm).
13. Verify the correct positions of the camshafts.
14. Remove the bracket tensioner.
15. Install or connect the following:
* Cylinder head-to-double bearing cap mating surface by lightly coating it with sealant. Tighten the remaining bearing caps to 84 inch lbs. (10 Nm).
* Camshaft gear. Tighten the bolt to 48 ft. lbs. (65 Nm).
* CMP shutter wheel and housing cover
* Valve cover
16. Align the camshaft gear and the vibration damper with the TDC markings.
17. Install or connect the following:
* Timing belt
* Accessory drive belts and the engine cover
* Lock carrier
* Negative battery cable
18. Fully close all power windows to stop, operate all window switches for at least 1 second in the close direction to activate the one-touch opening/closing function
CAUTION
After installing the lifters or the camshaft(s), the engine must NOT be started for at least 30 minutes. Otherwise the valves could strike the pistons. Rotate the engine by hand, at least 2 revolutions, to ensure that the valves do not strike the pistons.
