Genesis Coupe 2.0T Timing Chain Replacement DIY Pt.1

Introduction

This tutorial provides a comprehensive guide to replacing the timing chain on a Genesis Coupe 2.0T (BK1 and BK2 models, 2010-2014). Whether you're a DIY enthusiast or a professional mechanic, this step-by-step guide will walk you through the entire process, ensuring you understand the necessary steps and precautions.

Step 1: Preparation and Initial Disassembly

Before you start working on the timing chain, prepare your workspace and gather the necessary tools.

• Disconnect the negative terminal from the battery to ensure safety while working with electrical components.
• Remove the intake and coolant reservoir:
  • Unscrew the air duct connected to the intake.
  • Remove two 10mm bolts from the coolant reservoir.
• Ensure all components are set aside safely.

Step 2: Remove the Radiator Fan

• Locate the two 10mm bolts securing the OEM fan to the radiator.
• Disconnect the fan’s connector clip by pressing down on the tab and pulling it away.
• Once the bolts and connector are removed, lift the fan assembly out.

Step 3: Access the Timing Cover

• Before removing the timing cover, you need to loosen the tension on various components:
  • Loosen the bolts on the tensioners while the belt is still on to maintain tension.
• Remove the serpentine belt by using a 17mm breaker bar to relieve tension on the tensioner.

Step 4: Remove Pulleys and Crank Pulley

• Unscrew the following:
  • Two 15mm bolts and three 10mm bolts from the tensioners and idler pulleys.
  • The crank pulley, which is secured with a 22mm bolt:
    • Use vice grips to hold the crank pulley in place and a breaker bar to loosen the bolt.
• Keep an eye out for the crank pin; ensure it does not get lost.

Step 5: Remove the Power Steering Pump

• Take out the two 12mm bolts from the power steering pump.
• Use a mallet to gently tap the pump and free it from its mount.

Step 6: Drain Engine Oil

• Position a drain pan under the oil pan and remove the oil drain plug to allow the oil to fully drain.

Step 7: Disconnect Additional Components

• Remove the tensioner pulley (14mm or 15mm) and any coolant or vacuum lines.
• Detach the 10mm bolts securing the harness and disconnect the ignition coils.
• Remove the MAP and TIP sensor connectors.

Step 8: Remove the Valve Cover

• Take out all 10mm bolts securing the valve cover.
• If the valve cover is stuck, use a flathead screwdriver to gently pry it loose, being careful not to damage the cam gears.

Step 9: Remove the Timing Cover

• Unscrew all timing cover bolts (usually 10mm or 12mm).
• From underneath the vehicle, remove five 10mm bolts from the oil pan.
• Use a pry bar to gently break the seal on the timing cover and remove it.

Step 10: Remove the Timing Chain Components

• Begin with the timing chain tensioner, which is held in place by two 10mm bolts.
• Next, remove the timing chain guides:
  • Take note of the positioning for reinstallation.
  • There are multiple bolts (typically 10mm) securing the guides, so ensure you remove them carefully.

Conclusion

Congratulations! You have successfully removed the timing chain and its associated components from the Genesis Coupe 2.0T. Ensure that all parts are cleaned and inspected before proceeding with the installation of the new timing chain. For the next steps, consider sourcing the replacement parts and following the reverse process to install them. Remember to double-check all connections and ensure everything is torqued to specification for optimal performance.
