2014 Kia Rio (UB) 1.6 GDI Service & Repair Manual (P/N 28511-33361)

This service and repair manual covers the 2014 Kia Rio (UB) with the Gamma G4FD 1.6 GDI engine. It includes A6GF1 automatic and M6CF1 manual transaxle sections, plus body information for 4-door and 5-door configurations.

• Engine repair: Engine removal, cylinder-head and cylinder-block disassembly, timing-chain installation, CVVT inspection, valve-clearance adjustment, and internal wear measurements.

• Fuel and engine controls: GDI fuel-pressure testing, injector and high-pressure pump replacement, ECM terminal data, sensor waveforms, and electronic throttle learning.

• Transmission and clutch: Transaxle removal and installation, automatic valve-body and solenoid service, TCM learning, manual shift-cable adjustment, and clutch hydraulic bleeding.

• Brakes and chassis: Disc and drum brake service, ESC diagnosis, steering-angle calibration, suspension replacement, wheel alignment, and driveshaft joint repair.

• Electrical and restraints: System-specific wiring diagrams, BCM diagnosis, starting and charging tests, ISG battery-sensor recalibration, and SRS control-module variant coding.

• Body and climate control: Body dimensions, door and trim replacement, glass and seat procedures, air-conditioning service, and manual/FATC climate-control diagnosis.

The diagnostic and calibration sections suit technicians familiar with electrical testing and scan-tool operation, with access to GDS and the workshop equipment specified for the job.

Engine Mechanical Repair and Cooling

Cylinder-head and block procedures cover valve inspection, piston measurements, crankshaft checks, and bearing clearances. Timing-chain illustrations and CVVT/camshaft information accompany the installation procedures, while mechanical lash-adjuster selection supports valve-clearance correction.

Cooling-system coverage includes refilling and bleeding, thermostat testing, water-pump inspection and replacement, and radiator/fan checks. Lubrication information adds oil-pan service, oil-pressure specifications, and oil-flow diagrams.

GDI Fuel Delivery and Engine Diagnosis

The Symptom Troubleshooting Guide Chart connects starting, idle, and running complaints with relevant checks. ECM terminal and input/output tables distinguish manual and automatic configurations; these tables and sensor waveforms help narrow a circuit fault before a component is replaced.

Fuel-system procedures address low-pressure testing, residual-pressure release, injector sealing components, and high-pressure pump replacement. Electronic Throttle Control (ETC) testing and module learning are also covered.

The pump-removal cautions explain how uneven bolt release can damage the cylinder-head mounting surface. A separate installation warning links incorrect roller-tappet position to broken pump mounting bolts.

Automatic and Manual Transaxle Service

A6GF1 information explains torque-converter operation, hydraulic circuits, inhibitor-switch signals, and internal solenoid control. Valve-body replacement and TCM learning are supported by the Clutch & Brake Power Flow Chart, TCM connector views, and terminal-function tables.

M6CF1 procedures cover fluid service, assembly removal and installation, shift/select-cable adjustment, and backup-lamp switch checks. The separate clutch section addresses the cover, disc, master cylinder, release cylinder, and bleeding. The transmission sections do not provide complete internal gearset rebuilding procedures.

Brake, Steering, and Suspension Work

Brake procedures distinguish rear disc and drum arrangements and include parking-brake adjustment, hydraulic bleeding, and ESC fault diagnosis. ESC circuit diagrams support electrical checks alongside wheel-speed, yaw-rate, and steering-angle sensor information.

Steering coverage includes SAS zero-angle calibration and EPS Absolute Steering Position calibration/type recognition. The integrated EPS module is treated as a replacement assembly. Chassis procedures address front struts, the rear torsion beam, wheel alignment, hubs, and driveshaft joints.

Body Electrical, ISG, and SRS Systems

BCM circuit diagrams and terminal tables accompany lighting, window, locking, and immobilizer diagnosis. Starting and charging sections distinguish ISG components, AGM battery care, battery-sensor recalibration, the DC/DC converter, and the auxiliary electric transaxle oil pump.

The Continental Advanced restraint section includes SRSCM circuit diagrams, control-module Variant Coding, airbag replacement, and Weight Classification System service. High-pressure fuel and SRS work require the pressure-release and electrical-isolation precautions described in the manual.

Body Dimensions and Climate-Control Service

Separate body-dimension sections identify reference points for 4-door and 5-door bodies. Replacement procedures cover doors, trim, glass, seats, and bumpers.

HVAC information includes compressor replacement, refrigerant-system service, heater-unit removal, actuator testing, and diagnosis of manual and Fully Automatic Temperature Control systems.

Sample Sensor Specifications and Tightening Torques

These sensor and fastener values are a small selection of the technical data included in the manual.

For the A6GF1, the oil-temperature sensor table lists 48.1 kΩ at -40°C and 0.05 kΩ at 150°C. Specified sensor air gaps are 1.2–1.8 mm at the input and 0.85–1.3 mm at the output.

A6GF1 fastening data include 13.7–15.7 N·m for valve-body cover bolts and 34.3–44.1 N·m for the drain plug. Front brake caliper guide-rod bolts are listed at 21.6–31.4 N·m.

Searchable Text, Chapter Bookmarks, and Diagram Detail

Text search and diagram detail: Procedure and specification text supports PDF search, while many labels embedded in diagram images are not searchable. Sixteen embedded bookmarks open the main sections. Some small wiring labels and connector-pin numbers are pixelated and remain difficult to distinguish when enlarged.

Supplied as one printable, English-language 1,454-page PDF, containing the manual’s 16 system sections. The total includes all pages within those sections; no separate supplementary publications are included.
