Kia Sorento: Explanation of scheduled maintenance items
Engine oil and filter
The engine oil and filter should be changed at the intervals specified in the maintenance schedule. If the vehicle is being driven in severe conditions, more frequent oil and filter changes are required.
Inspect all drive belts for evidence of cuts, cracks, excessive wear or oil saturation and replace if necessary. Drive belts should be checked periodically for proper tension and adjusted as necessary.
Fuel filter (cartridge)
A clogged filter can limit the speed at which the vehicle may be driven, damage the emission system and cause multiple issues such as hard starting. If an excessive amount of foreign matter accumulates in the fuel tank, the filter may require replacement more frequently.
After installing a new filter, run the engine for several minutes, and check for leaks at the connections. Fuel filters should be installed by an authorized Kia dealer.
Fuel lines, fuel hoses and connections
Check the fuel lines, fuel hoses and connections for leakage and damage. Have an authorized Kia dealer replace any damaged or leaking parts immediately.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should be inspected at those intervals specified in the maintenance schedule. Make sure that a new vapor hose or fuel filler cap is correctly replaced.
Vacuum crankcase ventilation hoses (if equipped)
Inspect the surface of hoses for evidence of heat and/or mechanical damage. Hard and brittle rubber, cracking, tears, cuts, abrasions, and excessive swelling indicate deterioration. Particular attention should be paid to examine those hose surfaces nearest to high heat sources, such as the exhaust manifold.
Inspect the hose routing to assure that the hoses do not come in contact with any heat source, sharp edges or moving components which might cause heat damage or mechanical wear. Inspect all hose connections, such as clamps and couplings, to make sure they are secure, and that no leaks are present.
Hoses should be replaced immediately if there is any evidence of deterioration or damage.
Air cleaner filter
A Genuine Kia air cleaner filter is recommended when the filter is replaced.
Make sure to install new spark plugs of the correct heat range.
Valve clearance (if equipped)
Inspect for excessive valve noise and/or engine vibration and adjust if necessary. An authorized Kia dealer should perform the operation.
Check the cooling system components, such as the radiator, coolant reservoir, hoses and connections for leakage and damage. Replace any damaged parts.
The coolant should be changed at the intervals specified in the maintenance schedule.
Automatic transaxle fluid (if equipped)
Automatic transaxle fluid should not be checked under normal usage conditions.
But in severe conditions, the fluid should be changed at an authorized Kia dealer in accordance to the scheduled maintenance at the beginning of this section.
Manual transaxle fluid (if equipped)
Inspect the manual transaxle fluid according to the maintenance schedule.
Automatic transaxle fluid color is basically red. As the vehicle is driven, the automatic transaxle fluid will begin to look darker. It is the normal condition and you should not judge the need to replace the fluid based upon the changed color.
The use of a non-specified fluid could result in transaxle malfunction and failure. Use only specified automatic transaxle fluid.
Brake hoses and lines
Visually check for proper installation, chafing, cracks, deterioration and any leakage. Replace any deteriorated or damaged parts immediately.
Brake/clutch (if equipped) fluid
Check the brake fluid level in the brake fluid reservoir. The level should be between “MIN” and “MAX” marks on the side of the reservoir. Use only hydraulic brake fluid conforming to DOT 3 or DOT 4 specification.
Inspect the parking brake system including the parking brake lever (or pedal) and cables.
Brake discs, pads, calipers and rotors
Check the pads for excessive wear, discs for run out and wear, and calipers for fluid leakage.
Exhaust pipe and muffler
Visually inspect the exhaust pipes, muffler and hangers for cracks, deterioration, or damage. Start the engine and listen carefully for any exhaust gas leakage. Tighten connections or replace parts as necessary.
Suspension mounting bolts
Check the suspension connections for looseness or damage. Retighten to the specified torque.
Steering gear box, linkage & boots/lower arm ball joint
With the vehicle stopped and engine off, check for excessive free-play in the steering wheel.
Check the linkage for bends or damage. Check the dust boots and ball joints for deterioration, cracks, or damage. Replace any damaged parts.
Power steering pump, belt and hoses (if equipped)
Check the power steering pump and hoses for leakage and damage.
Replace any damaged or leaking parts immediately. Inspect the power steering belt (or drive belt) for evidence of cuts, cracks, excessive wear, oiliness and proper tension. Replace or adjust it if necessary.
Drive shafts and boots
Check the drive shafts, boots and clamps for cracks, deterioration, or damage. Replace any damaged parts and, if necessary, repack the grease.
Air conditioning refrigerant
Check the air conditioning lines and connections for leakage and damage.
