Pre-Cut Firewall Insulation Pad – Nissan GU and GQ Patrol

Over time, the original firewall insulation in Nissan GU and GQ Patrols deteriorates, crumbles, and breaks down, ultimately failing to provide effective thermal and acoustic protection. Once compromised, heat and engine noise can easily transfer into the cabin, impacting comfort. Whether your firewall pad is damaged, missing, or beyond its lifespan, Car Builders premium pre-cut firewall insulation pad is the perfect OEM-style replacement, restoring comfort and protection to factory standards.

Suits GU model (ZD30 engine models from Sept 2001 to Dec 2012, and GU Utes Dec 2002 to Dec 2012), this pad is designed for a seamless fit and easy installation.

Upgrade Your Firewall Insulation with These Add-Ons

1. Sound Deadener Sheets – Extra Noise Reduction

For better acoustic control, pair your firewall insulation with Car Builders Sound Deadener Sheets. These vibration-damping sheets target and reduce structure-borne noise, minimising sound transfer from engine and road vibrations into the cabin.

• Includes 6 sheets (300mm x 500mm)
  Dampens vibrational noise from the engine bay
  Enhances the effectiveness of the firewall insulation

Installation:

1. Map out the sheets before installing to ensure complete coverage.
2. Clean the firewall thoroughly to remove any dirt or grime.
3. Apply the Sound Deadener Sheets directly onto the firewall, then install the pre-cut firewall insulation over the top for a layered noise and heat barrier.

2. Application Roller – Ensure Long-Lasting Adhesion

For optimal adhesion and longevity, we recommend using the Car Builders Application Roller during installation. Proper surface preparation and even pressure are key to ensuring a strong, long-lasting bond for both Sound Deadener Sheets and Firewall Insulation.

✅ Ensures even pressure across the material for a secure bond
✅ Handle doubles as a convex tool to form products into irregular shapes
✅ Radiused wheel to prevent marks and tearing—common with cheaper square-edged urethane rollers

Key Features of the Firewall Insulation Pad:

✅ Vehicle-Specific Fit – Precisely cut to match the firewall contours of the Nissan GU Patrol for an easy, factory-like installation.
✅ Premium Underbonnet Insulation (PUB) – Manufactured using our durable needle-punched polyester, designed to resist heat, moisture, and wear for long-lasting performance.
✅ Self-Adhesive Backing – No messy glues or fasteners required—simply peel and stick for a secure hold.
✅ Superior Cabin Comfort – Reduces engine noise and heat transfer, creating a cooler, quieter driving experience.
✅ Resilient & Washable – Designed to withstand high-pressure washing without deteriorating.
✅ Non-Ignitable & Heat Resistant – Built from materials that can withstand up to 405°F (207°C), providing fire safety and thermal protection.
✅ Sleek OEM Appearance – Finished in 100% black, maintaining a clean, factory look under the bonnet.

Enhance Your Firewall Protection Further

For extreme heat applications, such as turbocharged setups or areas where engine components are positioned close to the firewall, we recommend reinforcing your insulation with Car Builders Peel & Stick Heat Shield. A common strategy is to install the firewall replacement pad as normal and, in areas with extreme heat exposure, cut the pad and apply Peel & Stick Heat Shield for targeted protection.

This high-performance thermal barrier is constructed from needle-punched fibreglass with a durable aluminium face, tested to withstand 475°F (246°C) for 30 hours with no failure.

Easy DIY Installation – Pro Tips & Tricks

Preparation:

• Thoroughly clean the firewall using a wax and grease remover to ensure strong adhesion.
• Trial fit the insulation before peeling the backing to confirm alignment with all holes and contours.

Installation:

1. Apply Sound Deadener Sheets First (If Using) – Roll the sheets firmly onto the firewall for vibration reduction.
2. Start at the Centre – Identify the middle of the firewall and peel back a small section of the insulation backing.
3. Secure in Sections – Apply the adhesive to the centre first, then gradually work outward, peeling as you go. Avoid stretching the material.
4. Firmly Roll Down – Once positioned correctly, use the Application Roller to press the insulation down evenly, ensuring a strong bond.
