The manufacturer provides for the replacement of the timing belt every 60,000 km or every 6 years. In addition, the timing belt should be replaced if there are traces of oil on its surface, or if the belt is worn or damaged in any way. Replacement of the belt is carried out at the inspection pit, overpass or lift.
Necessary
- - Special fixing devices for camshafts, crankshaft and belt tensioner;
- - socket wrench for 10, ring wrenches for 8, 13 and 18;
- - factory instructions for service and repair.
Instructions
Step 1
First of all, remove the belts of the A / C compressor drives and ancillary assemblies. Remove the generator. Then remove the expansion tank (you can simply move it aside without disconnecting the hoses). Considering that the engine mount must be removed to change the belt, support the engine securely. Then remove the right front engine mount. To do this, unscrew the 2 nuts securing the support to the bracket and unscrew the 2 fastening bolts.
Step 2
Remove the 4 bolts securing the water pump pulley and remove the pulley. Remove the 3 bolts securing the right engine mount bracket and remove this bracket. Unscrew the 8 bolts securing the timing belt cover and remove it. Check the transmission lever: it must be in neutral. Then crank the crankshaft until the VCT markings point straight up. At the front of the cylinder block on the right side, locate and remove the plug that covers the crankshaft lock hole. Insert the crankshaft locking rod into this hole and turn the crankshaft until it is completely blocked.
Step 3
Find the special grooves in the VCT housings and insert the camshaft clips into them so that the marks on the clips are at the top. The line mark should be on the exhaust camshaft side, the dot mark should be on the intake side. Move the transmission lever to 4th gear. Automatic transmission selector to parking position. Apply the parking brake.
Step 4
Remove the crankshaft pulley by unscrewing its mounting bolt. In the future, when assembling, install only a new pulley mounting bolt. Remove the bottom cover by unscrewing the 3 bolts of its fastening. To loosen the timing belt, pull its leading branch as far as possible. The tensioner roller should return to its original position. Secure this roller with a retainer or a suitable steel rod by placing it in the holes of the roller and its bracket.
Step 5
Remove the timing belt from the VCT pulleys, crankshaft and idler pulley. Make sure that the crankshaft is not rotated in any case when the belt is removed. When installing a new belt, begin by sliding it onto the VCT pulley. Then slide it over the crankshaft pulley and then slide it over the roller. After checking that the belt is fitted correctly, remove the tension roller retainer. In this case, he must set the desired belt tension.
Step 6
Install the lower timing belt cover and crankshaft pulley. Tighten the crankshaft pulley mounting bolt to 4.0 kgf-m (40 Nm), then tighten 90 degrees. Remove the camshaft and crankshaft clips. With the gear in neutral, turn the crankshaft 2 turns. Stop the crankshaft so that the marks of the VCT mechanisms point straight up. Then follow the above procedure for fixing the crankshaft and camshafts. If this operation takes place without difficulty, the timing belt is installed correctly.
Step 7
If you have difficulty installing the clips, reinstall the timing belt. In case of correct installation, remove the VCT mechanism retainer, install the hole plug of this retainer. Tighten to 20 Nm. Install all removed parts in reverse order.
