1990 Hyundai Sonata Service and Repair Manual
Fitment comes first on the 1990 Hyundai Sonata: this factory service and repair manual is tied to the exact year, engine and trim in front of you, so the clearances, torque values and service sequences it gives are the ones Hyundai published for this car instead of numbers borrowed from an adjacent model year.

Known issues on the 1990 Sonata. Three recalls sit on federal record for this model year. One covers the seat belts: the motorized shoulder belt can travel slowly or chatter in the track and may eventually stop tracking and become inoperative, and that slowing, chattering or failure may discourage use of the restraint. A second covers the hood latch, where insufficient clearance could cause the safety catch on the secondary hood latch striker to bind; if the primary latch is released or the hood is not completely closed, the hood could fly open. The third covers the engine cooling hoses: the spring clamp tangs on the coolant bypass hose may contact and possibly damage the engine fuel supply hose, and fuel could leak from the damaged hose into the engine compartment and could result in a fire. Owners have filed 25 complaints for the year and Hyundai has issued 9 technical service bulletins.
Whether you are freeing a balky motorized belt track, checking secondary hood latch clearance or routing the coolant bypass hose clear of the fuel supply line, it keeps you on Hyundai's own procedure and specification for this 1990 Sonata.
THE MOTORIZED SHOULDER BELT CAN TRAVEL SLOWLY OR CHATTER IN THE TRACK AND MAY EVENTUALLY STOP TRACKING AND BECOME INOPERATIVE.
SLOWING, CHATTERING, OR FAILURE OF THE MOTORIZED SHOULDERBELT MAY DISCOURAGE USE OF THE RESTRAINT SYSTEM, INCREASING THE RISK OF INJURYIN THE EVENT OF A SUDDEN STOP OR ACCIDENT.
DEALERS WILL LUBRICATE THE TRACK ASSEMBLY AND, IF ANY SYSTEMS ARE FOUND INOPERATIVE, THE SYSTEM WILL BE REPAIRED OR REPLACED, AS REQUIRED.
INSUFFICIENT CLEARANCE COULD CAUSE THE SAFETY CATCH ON THE SECONDARY HOOD LATCH STRIKER TO BIND.
IF PRIMARY LATCH IS RELEASED OR IF HOOD IS NOT COMPLETELY CLOSED, HOOD COULD FLY OPEN WHILE VEHICLE IS IN MOTION; THIS WOULD BLOCK DRIVER'S VISION AND COULD RESULT IN AN ACCIDENT.
REPLACE HOOD LATCH STRIKER ASSEMBLY.
THE SPRING CLAMP TANGS ON THE COOLANT BYPASS HOSE MAY CONTACT AND POSSIBLY DAMAGE THE ENGINE FUEL SUPPLY HOSE.
FUEL COULD LEAK FROM THE DAMAGED HOSE INTO THE ENGINE COMPARTMENT AND COULD RESULT IN A FIRE.
ROTATE SPRING CLAMP TO PREVENT CONTACT WITH FUEL HOSE; REPLACE DAMAGED HOSES.
