    Technical Notes:

    Over time, the factory plastic coolant expansion tanks that Honda/Acura include from the factory can weaken and fail from heat and pressure cycles. The PRL Coolant Expansion Tank kit replaces the factory tank with a more robust aluminum version. Our 6061 aluminum tank will not be effected by temperature and can hold higher pressures so it will out-last the factory tank. Our reservoir also more than doubles the tank's coolant capacity to 1.32 quarts (1.25 liters), while the stock tank only holds .58 quarts (.55 liters) allowing for a greater volume of coolant to carry heat away from the engine internals while maintaining a tidy engine bay. Our tank is constructed from 3mm thick aluminum and features internal baffling to prevent coolant sloshing and cavitation. The kit includes all necessary fittings to fit either the FK8/FL5/DE5 Civic Type-R/Integra Type-S applications as well as the fittings needed to fit the 2016-2021 Civic with the 1.5t engines.

    Key Notes:

    • Robust 3mm 6061 Aluminum Construction
    • Laser Cut and TIG Welded for Unmatched Fit and Finish
    • Striking Red or Black Anodized Finish with Laser Engraved Logos
    • Billet Machined Barb Fittings and Sight Glass
    • Buna-N O-Rings for Unmatched Temperature and Leak Resistance

    Kit Includes:

    • Fully welded and anodized expansion tank (red or black)
    • 1x 1/16” NPT 8mm barb fitting
    • 2x 8AN ORB 14mm barb fittings
    • 1x 8AN ORB 17mm barb fitting
    • 1x 8AN ORB 8mm barb fitting
    • 1x 10AN sight glass

    Damaged Shipments

    If your shipment arrives damaged, whether visible upon delivery or discovered after opening the package, please follow these steps immediately:

    • Contact Gearhead Motoring as soon as possible and submit a damage claim at shipping@gearheadmotoring.com
    • Keep all original packaging materials, including the box and packing materials.
    • Make a list of any damaged or missing items.
    • Take clear photos of the damaged packaging and the affected products.
    • If the delivery driver cannot wait for an inspection, or does not allow you to inspect the shipment, write "SUBJECT TO INSPECTION" on the delivery receipt before signing and ask the driver to acknowledge it.

    Once we receive the required information, Gearhead Motoring will work directly with the shipping carrier and arrange a pickup if necessary. Do not return any merchandise without prior written authorization and an RMA number from Gearhead Motoring.

    After the returned product is received and inspected, we will notify you whether the item will be replaced, or if a refund or store credit will be issued.

    Important: By signing and accepting a freight shipment, you may waive your right to file a damage claim for any damage not noted on the delivery receipt. We strongly recommend inspecting all freight shipments upon arrival, even if the outer packaging appears to be in good condition.
