Kia 243702G750 Cvvt Assembly-Exhaust

The timing system is complex, and severe engine damage will occur if mistakes are made, so only highly experienced individuals should attempt this procedure. Disconnect the cable from the negative terminal of the battery, remove the engine cover, drivebelt, alternator, and power steering pulley without disconnecting the hoses. Remove the tensioner, idler pulley, NC compressor without opening refrigerant lines, and secure it out of the way. Raise the front of the vehicle, support it securely, and remove the right front wheel. Remove the lower and upper oil pans, radiator, and coolant reservoir. For 2011 and later models, support the engine from above, remove the upper engine mounts, and loosen the transaxle mount. Remove the valve covers, support the engine from below, disconnect the power steering hose, and remove the mount. Set the number one cylinder to TDC on the compression stroke, remove the crankshaft pulley, lift the engine mount bracket, and remove the timing chain cover while laying out the bolts in order. Verify the number one cylinder is still at TDC, paint match marks on the sprockets, compress the right chain tensioner, and remove the right upper chain guide, tensioner, and chain. Remove the right chain guide, oil pump chain cover, chain tensioner, oil pump sprocket, and chain, followed by the crankshaft gear for the oil pump and right timing chain, then remove the components for the left timing chain in the same order. Inspect all parts for wear and damage, checking the timing chain, sprockets, chain guides, and automatic tensioners for any issues. Clean the timing belt area, align the crankshaft key and camshafts with their TDC marks, install the timing chain guide, chains, tensioner arm, and upper cam-to-cam guide, then pull the pins out of both chain tensioners. Install the oil pump chain guide and tensioner, rotate the engine two complete turns clockwise, and verify that the marks on all six sprockets are properly set. Clean the timing chain cover sealing surfaces, apply RTV silicone sealant where necessary, tighten the timing chain cover bolts to the specified torque, and complete the installation in reverse order of removal.

The timing system is complex, and severe engine damage will occur if mistakes are made, so only highly experienced individuals should attempt this procedure. Disconnect the cable from the negative terminal of the battery, remove the engine cover, loosen the right front wheel lug nuts, raise the front of the vehicle securely on jack stands, and remove the engine under cover. Remove the right front wheel and the right engine cover, then set the engine at TDC on the number one cylinder, ensuring all timing marks are aligned. Loosen the pulleys on the power steering pump, idler pulley, and crankshaft pulley, then remove the drive belt and the automatic tensioner. Support the engine with a floor jack, place a block of wood between the jack head and the engine, and remove the right engine mounting bracket. Remove the power steering pump pulley, idler pulley, and crankshaft pulley, followed by the upper and lower timing belt covers. If the timing belt is to be reused, mark it with an arrow indicating direction of travel and match marks from the belt to the sprockets for easy realignment. Remove the timing belt tensioner and then the timing belt, taking care not to turn the crankshaft or camshafts during this process. To remove the camshaft sprockets, remove the valve covers and hold the hex area of the camshaft securely with a wrench while removing the bolts. Inspect the belt for oil or dirt and visible defects, check the tensioner for oil leakage, and test the tensioner for leakdown. Remove all dirt, oil, and grease from the timing belt area, install the camshaft sprockets if removed, and align the pin hole in the sprocket with the pin in the end of the camshaft. Install the camshaft sprocket bolts and tighten them to the specified torque, ensuring all camshaft sprocket marks align with the engine marks. Compress the timing belt tensioner pushrod slowly, insert a metal pin, and then install the timing belt tensioner, tightening the bolts to the specified torque. Place the timing belt around the sprockets and pulleys in the correct order, verify that all timing marks are aligned, and pull the pin from the tensioner. Turn the crankshaft slowly through two complete revolutions by hand, and if any resistance is felt, stop immediately to check for issues. Let the engine sit for five minutes at TDC, then check the protrusion of the tensioner rod, replacing it if necessary. The remainder of the installation follows the reverse order of removal.
