Honda Civic 1.5L Turbo Gasket Replacement Guide

Quick answer

Replace the exhaust gasket on your 2022+ Honda Civic 1.5L Turbo or Acura Integra using a REMARK Replacement Gasket and Hardware Set. Follow these steps to avoid leaks and ensure a proper seal.

Step-by-step gasket replacement

1. 1. Prepare the vehicle: Park on a level surface, let the exhaust cool completely, and disconnect the battery negative terminal. Raise the vehicle securely on jack stands and locate the catback exhaust flange where it meets the turbo outlet. Working on a hot exhaust can cause burns and damage gaskets. Always let it cool.
2. 2. Remove the old gasket and hardware: Using a socket wrench, remove the bolts or nuts securing the catback exhaust to the turbo outlet flange. Carefully pull the exhaust back and remove the old gasket. Inspect the flange surfaces for debris or damage. If the old gasket is stuck, use a plastic scraper to avoid scratching the metal.
3. 3. Install the new gasket and hardware: Place the new gasket from the REMARK kit onto the turbo outlet flange, aligning the bolt holes. Apply a thin layer of anti-seize compound to the new hardware threads. Reattach the catback exhaust and tighten the bolts evenly in a cross pattern to the manufacturer's torque specification (typically 25-35 ft-lb). Over-tightening can warp the flange or crush the gasket. Use a torque wrench for accuracy.
4. 4. Test for leaks: Reconnect the battery, start the engine, and let it idle. Listen for hissing or whistling sounds near the flange. Use a soapy water spray to check for bubbles around the joint. If no leaks are present, take a short test drive and recheck after cooling. A small leak may only appear under load. Recheck after a test drive to be sure.
