A new type of bolts, to be tightened in plastic area, is currently used in some parts of the engine. The tightening method for the bolts is different from the conventional one. Be sure to observe the method described in the text when tightening the bolts.
Service limits are provided for the bolts. Make sure that the service limits described in the text are strictly observed.
JAreas where the bolts are in use:
(1)Cylinder head bolts
(2)Main bearing cap bolts
(3)Connecting rod cap bolts
JTightening Method
After tightening the bolts to the specified torque, tighten them another 90è to 100è, or 240è (twice 120è). The tightening method varies on different areas. Observe the tightening method described in the text.

*: parts sealed by foam-in-place gasket (FIPG)
K Mitsubishi Motors Corporation |

6A1 ENGINE (E-W) - Specifications |
The engine has several areas where the form-in-place gasket (FIPG) is in use. To ensure that the gasket fully serves its purpose, it is necessary to observe some precautions when applying the gasket. Bead size, continuity and location are of paramount importance. Too thin a bead could cause leaks. Too thick a bead, on the other hand, could be squeezed out of location, causing blocking or narrowing of the fluid feed line. To eliminate the possibility of leaks from a joint, therefore, it is absolutely necessary to apply the gasket evenly without a break, while observing the correct bead size.
The FIPG used in the engine is a room temperature vulcanisation (RTV) type and is supplied in a 100-gram tube (Part No. MD970389 or MD997110). Since the RTV hardens as it reacts with the moisture in the atmospheric air, it is normally used in the metallic flange areas. The FIPG, Part No. MD970389, can be used for sealing both engine oil and coolant, while Part No. MD997110 can only be used for engine oil sealing.
Disassembly
The parts assembled with the FIPG can be easily disassembled without use of a special method. In some cases, however, the sealant between the joined surfaces may have to be broken by lightly striking with a mallet or similar tool. A flat and thin gasket scraper may be lightly hammered in between the joined surfaces. In this case, however, care must be taken to prevent damage to the joined surfaces. For removal of the oil pan, the special tool “Oil Pan Remover” (MD998727) is available. Be sure to use the special tool to remove the oil pan.
Surface Preparation
Thoroughly remove all substances deposited on the gasket application surfaces, using a gasket scraper or wire brush. Check to ensure that the surfaces to which the FIPG is to be applied is flat. Make sure that there are no oils, greases and foreign substances deposited on the application surfaces. Do not forget to remove the old sealant remained in the bolt holes.
Form-in-Place Gasket Application
When assembling parts with the FIPG, you must observe some precautions, but the procedures is very simple as in the case of a conventional precut gasket.
Applied FIPG bead should be of the specified size and without breaks. Also be sure to encircle the bolt hole circumference with a completely continuous bead. The FIPG can be wiped away unless it is hardened. While the FIPG is still moist (in less than 15 minutes), mount the parts in position. When the parts are mounted, make sure that the gasket is applied to the required area only. In addition, do not apply any oil or water to the sealing locations or start the engine until a sufficient amount of time (about one hour) has passed after installation is completed.
The FIPG application procedure may vary on different areas. Observe the procedure described in the text when applying the FIPG.

+BG AUTO TENSIONER SETTING
(1)Set the auto tensioner in a vice, while making sure it is not tilted.
(2)Slowly close the vice to force the rod in until the set hole (A) of the rod is lined up with the set hole (B) of the cylinder.
(3)Insert a 1.4 mm wire in the set hole.
(4)Remove the auto tensioner from the vice.
+CG TIMING BELT INSTALLATION
(1)Turn the crankshaft sprocket so that its timing mark will be away from the mating timing mark by approx. three teeth.
Caution
J If the timing marks are aligned, the piston is brought to the TDC. When the camshaft is turned under this condition, the valves may interfere with the piston.
(2)Bring the timing marks of the camshaft sprockets as shown in the illustration.

(3)Align the timing mark on the crankshaft sprocket with that on the cylinder block side.
(4)Fit the timing belt on the sprockets in the following order:
1)Fit the timing belt on the crankshaft sprocket and then, while giving tension to the belt, fit it on the water pump sprocket.
2)Fit the belt on the left bank camshaft sprocket.
3)Fit the belt on the idler pulley while keeping it tight.
4)Align the timing mark on the right bank camshaft sprocket with the mark on the cylinder block, and then fit the belt on the camshaft sprocket.
Caution
JThe camshaft sprockets are prone to rotate. Avoid giving excessive tension to the timing belt when it is fitted.
5)Make sure that the left bank portion of the belt is not slack when the belt is fitted on the tensioner pulley. If it is slack, remove the belt and fit it again beginning with the first step.
(5)Move the tensioner pulley in the direction of the arrow and hold it in raised position by tightening the tensioner pulley bolt.
(6)Check that all timing marks are aligned correctly.
(7)Turn the crankshaft counterclockwise a quarter turn.
(8)Turn back the crankshaft clockwise until the timing marks align again.
(9)Install the special tool and a torque wrench of 0 - 5 Nm to the tensioner pulley.
(10)Torque the tensioner pulley to 3 Nm with the torque wrench.
(11)While holding the tensioner pulley, tighten the center bolt to specification.
(12)Turn the crankshaft clockwise 2 turns and let it stand for about 5 minutes.

+DG TIMING BELT INSTALLATION
(1)Turn the crankshaft sprocket so that its timing mark will be away from the mating timing mark by approx. three teeth.
Caution
J If the timing marks are aligned, the piston is brought to the TDC. When the camshaft is turned under this condition, the valves may interfere with the piston.
(2)Bring the timing marks of the camshaft sprockets as shown in the illustration.
Caution
J If one of the camshaft sprockets on the right bank is turned with the timing mark on the other sprocket aligned, there may be danger for the intake and exhaust valves to interfere with each other.
(3)Align the timing mark on the crankshaft sprocket with the mating timing mark, and then turn the crankshaft counterclockwise by one tooth.
(4)Place the timing belt over the sprockets in the following method.
Caution
J The camshaft sprockets on the right bank can turn very easily because of the valve spring tension. Use care not to allow your fingers to get caught between the sprockets.
1) Align the timing mark of the right bank exhaust camshaft sprocket with the mating timing mark and hold the timing belt on the sprocket with a paper
clip.
2) Align the timing mark of the intake camshaft sprocket and place the timing belt around that sprocket. Then, clip the belt at the location shown.
Caution
JThe camshaft sprockets can turn easily and do not give excessive tension to the timing belt.
3)Place the timing belt around the idler pulley.

4)On the left bank, make sure that the timing marks of the camshaft sprockets are aligned and then hold the timing belt on these sprockets with paper clips.
5)Place the timing belt around the water pump pulley.
6)Place the timing belt around the crankshaft sprocket.
7)Place the timing belt around the tensioner pulley.
(5)Move the tensioner pulley in the direction of the arrow and hold it in raised position by tightening the tensioner pulley bolt.
(6)Check that all timing marks are aligned correctly.
(7)Turn the crankshaft counterclockwise a quarter turn.
(8)Turn back the crankshaft clockwise until the timing marks align again.
(9)Install the special tool and a torque wrench of 0 - 5 Nm to the tensioner pulley.
(10)Torque the tensioner pulley to 3 Nm with the torque wrench.
(11)While holding the tensioner pulley, tighten the center bolt to specification.
(12)Turn the crankshaft clockwise 2 turns and let it stand for about 5 minutes.
(13)Make sure that the wire, which has been inserted when installing the auto tensioner, can be removed easily. Belt tension should be acceptable if the wire can be easily removed. Remove the wrench. The belt tension can also be verified by checking the protrusion amount of the auto tensioner rod which should conform to the following.
Standard value: 3.8 - 4.5 mm
(14)If the wire cannot be removed easily or the rod protrusion is not up to specification, repeat steps (9) through (12) to obtain the correct tension.
INSPECTION
TIMING BELT
Replace belt if any of the following conditions exist.
(1)Hardening of back rubber.
Back side is glossy without resilience and leaves no indent when pressed with fingernail.
