Take off the cable from the negative terminal of the battery. Remove coolant from cooling system and engine oil also. Take away such components as engine cover, air filter housing, air intake duct, drivebelt, engine cooling fans and air conditioning compressor. Then there are alternator, drivebelt tensioner, idler pulleys, vibration damper and power steering pump to be removed. Get dipstick tube, oil pan, pickup tube, heater hoses, water pump, timing cover bolts and front cover out of the way. Remove an oil pump too. Reinsert a bolt in the end of the crankshaft, now turn it until it puts a crankshaft sprocket timing mark at 6 o'clock position and camshaft timing mark at 12 o'clock position. Withdraw a tensioner and install a drill bit to secure it in this retracted place. Remove all traces of old gasket material or sealant from your shop rag that is plugged into an opening at front side portion of oil pan's drain hole. Run screwdriver blade between lower edge of oil pan's sealing surface on an engine block as well as upper edge of old gasket material or sealant compressing tensioner spring. The appropriate tightening sequence for these bolts on each side needs to be followed here. Drain plug should not be over tightened or it will make removal difficult later when changing fluids. Fill coolant reservoir slowly with thirty percent ethylene glycol solution to avoid possible overheating which may occur due rapid change in temperature. Run in engine and inspect for leaks. Do not run without radiator cap installed if coolant has reached operating temperature first. Therefore all nomenclature mentioned above can be used interchangeably. Transmission fluid is checked using special probes or sensors installed. Transmission fluid level is checked under vehicle running conditions. Techs should check transmission fluid while vehicles are performing operations. Similarly, transmission fluid should be determined with regard to many factors including how often you run car. Transmission fluid should be checked as part of preventive maintenance routine. Transmission fluid level is determined by variations in temperature. Transmission fluid is supposed to be changed once a while. It is advised that transmission fluid can only be analyzed using dipstick which can measure the amount of fluid in it. Hence, transmission fluid should only be examined using dipstick.

Timing is highly complicated, and any error is fatal to the engine, it will require replacement. This procedure should only be attempted by most experienced individuals, and any doubt regarding the skills should call an expert. Check and recheck all the works to be correct before turning on the engine. Any wet cylinder liner is a potential source of cavitation damage and must not be rotated when the crankshaft or camshafts are rotated separately, which may damage the valves. Several specialist instruments are necessary for the completion of these procedures, so check they are procured before commencement. First, that involved removing the multi-pin connector from the negative terminal of the battery, lifting the front of the car up on jackstands, and then siphoning out the engine oil and coolant. Take off the drivebelt, the drivebelt tensioner, idler pulley, thermostat housing and upper radiator hose and the heater hose from the water pump. Loosen and clear heater core supply pipe, remove the power steering pump, crank balancer, and all the valve covers being careful not to let the magnetic timing wheels touch any magnet. Take out the lower and upper oil pans, timing cover mounting bolts and they should be able to pry the cover gently. To do this, just pinch the crankshaft pulley bolt, and then rotate the crankshaft until both timing marks are exactly aligned and are on the TDC number one on the exhaust stroke. If camshaft phasers are add-on parts, make sure that the marks on phasers are aligned with the plated links. Compress the chain tensioners, remove timing gear splash shield, oil pump tensioner and the oil pump sprocket, mark the oil pump for the direction of the chain installation. The camshaft phaser lock tools should be installed, the nuts on the oil control valves to be loosened, and, at last, the camshaft phasers and timing chains wanted. If located, then check the timing chain dampener for wear and also clean the timing chain and sprockets if necessary and replace them. Before turning the engine on, try to turn the crankshaft at least 2 turns round as you apply resistance at the floor end. Reset and renew the gasket material and sealant, place the chain guides and tensioners then consider the keyway on the crankshaft. Synchronize the primary chain on the crankshaft sprocket then apply clean engine oil on the sprockets and chain and by positioning the marks install the assembly. Strengthen the tightened idler sprocket fastener and put the primary chain guide and tensioner and take off the special tool from the tensioner plunger. For the left side camshaft phaser and the right side camshaft phaser, put the oil control valve and fix it properly and tight. In the position as installed, oil pump timing chain, timing chain tensioner, sprocket, and splash shield should align all special marks, rotate engine for recheck the alignment. I have fitted new coolant housing and water pump housing gaskets, applied RTV sealant to the cover, I then bolt it to the alignment dowels. Leverage up the cover bolts in a star like fashion and perform other connections in the reversed manner. Last, include oil or coolant, engage the engine, and search for any dripping.

Take off the cable from the negative terminal of the battery. Remove coolant from cooling system and engine oil also. Take away such components as engine cover, air filter housing, air intake duct, drivebelt, engine cooling fans and air conditioning compressor. Then there are alternator, drivebelt tensioner, idler pulleys, vibration damper and power steering pump to be removed. Get dipstick tube, oil pan, pickup tube, heater hoses, water pump, timing cover bolts and front cover out of the way. Remove an oil pump too. Reinsert a bolt in the end of the crankshaft, now turn it until it puts a crankshaft sprocket timing mark at 6 o'clock position and camshaft timing mark at 12 o'clock position.

The air conditioning compressor should be removed without disconnecting the hoses, using rope or wire to secure it away from the engine.
