How to Align the Timing Chain of a Kia Forte?

[StOlive]

The method for aligning the timing chain of a Kia Forte is as follows: 1. Ensure the crankshaft is at the top dead center of the first cylinder, rotate the notches at the rear end of the intake and exhaust camshafts to a horizontal position, then attach the chain and accessories; 2. Secure the crankshaft pulley to the front cover with a 6mm screw, fix the crankshaft through the gear ring, and tighten the crankshaft pulley screw. Taking the 2019 Kia Forte as an example, its body structure is a 4-door, 5-seater sedan with body dimensions of: length 4510mm, width 1750mm, height 1470mm, a wheelbase of 2650mm, front track of 1542mm, rear track of 1553mm, a fuel tank capacity of 50 liters, and a curb weight of 1140kg.

When I used to work on used cars, I did the timing chain alignment on a Forte by myself. The key is to align the chain marks with the timing marks on the crankshaft and camshaft. First, remove the valve cover and chain cover, loosen the crankshaft bolt with an impact wrench, and rotate the crankshaft counterclockwise to the top dead center of cylinder one. At this point, the camshaft positioning hole should face upward, and use a special tool to lock the camshaft gear. Then, release the chain tensioner and remove the old chain. When installing the new chain, make sure the three colored chain links align with the crankshaft timing gear mark, balance shaft gear mark, and camshaft VVT actuator mark. Finally, don’t forget to tighten the crankshaft bolt to the manual-specified torque, which is about 90Nm. For those without special tools, I recommend going to a repair shop. Misalignment can cause minor issues like triggering a fault light or, in severe cases, valve damage.

Aligning the timing chain on the Forte is most critical to avoid misaligned marks. First, disconnect the negative battery terminal and lift the vehicle to remove the right front wheel for easier access. To position the crankshaft, insert a long screwdriver into the No. 1 spark plug hole and feel for the piston reaching the top dead center. The camshaft must be secured using a Kia-specific tool that locks the hexagonal hole at the back; otherwise, the shaft will rotate when tightening the VVT actuator bolt. Pay special attention to aligning the small dot mark on the balance shaft gear with the blue link of the chain. After installing the chain, manually rotate the crankshaft two full turns to recheck the marks. If the tensioner clip isn't properly installed or the chain skips a tooth, a clicking noise will occur upon starting the engine.

Last week, I just helped a friend replace the chain on a 2012 Kia Forte. The chain lifespan for this car is around 100,000 kilometers. When it stretches, it will make a rattling noise at idle. The key to alignment is positioning: After confirming the top dead center of cylinder 1, the camshaft gear positioning hole should face directly upward; the crankshaft balancer shaft notch mark should also face upward; compare the old and new chains to confirm the amount of stretch. The tricky part of the operation is removing and installing the crankshaft pulley, which requires an impact wrench. If a P0016 fault code appears after a cold start upon reassembly, there's an 80% chance the camshaft phase is misaligned, and it will need to be disassembled and reinstalled.

As a mechanic, here are some key points to remind you: Mark the direction of the old chain before removal; Do not use a screwdriver to forcefully secure the crankshaft fixing tool as it may damage the threads; When fixing the camshaft tool with M6 bolts, do not exceed 8Nm to avoid bolt breakage; Align the blue mark of the balance shaft chain with the gear groove; Align the yellow link of the main chain with the crankshaft keyway. Most importantly, use a pin to lock the tensioner before installation, then remove the pin after installation to allow the ratchet to work. Finally, use a diagnostic tool to read the camshaft learning values to confirm successful calibration.

There are three major pitfalls when timing the engine: inaccurate positioning (use a cylinder pressure gauge to confirm the top dead center of the compression stroke in cylinder one), misaligned marks (the Forte has three marks on the crankshaft sprocket balance shaft), and insufficient chain pre-tension (rotating the crankshaft without releasing the tensioner lock pin can cause the chain to skip teeth). Essential tools for DIY include an E14 socket for removing the timing chain cover, a 19mm socket for loosening the crankshaft bolt, and a dial-type torque wrench. After reassembly, disconnect the fuel injector plug and let the engine idle for ten seconds before starting to allow the oil pump to build up pressure, which can reduce phase deviation in the VVT system caused by oil starvation.
