    Common Questions

    Q: Will this fit my 1991 GMC C2500 with a 5.7L V8? Is this different from a standard radiator?
    A: Yes, this 3-row aluminum radiator is specifically engineered for 1988-1993 Chevrolet and GMC C/K 1500, 2500, and 3500 trucks with the 5.7L V8 engine, and is particularly suited for Heavy Duty (HD) models. It is a performance upgrade over the standard radiator, designed for better cooling under heavy loads. It is compatible with both Automatic (AT) and Manual (MT) transmissions as it includes the necessary cooler ports.
    Q: How difficult is it to install this HD radiator on my C3500 work truck?
    A: For someone with mechanical experience, installation on a 1988-1993 C/K HD truck is straightforward. This radiator is designed as a direct-fit replacement, meaning it uses the factory mounting locations and hose connections for an easy swap. The process involves draining the coolant, removing the fan shroud and old radiator, and installing the new one. On a work truck, it is highly recommended to inspect and replace worn radiator hoses, hose clamps, and the fan clutch at the same time.
    Q: How does this HD radiator improve performance when towing with my 5.7L V8?
    A: This Heavy-Duty 3-row radiator is essential for towing and hauling. The 5.7L V8 engine generates significant heat under load. This radiator's 3-row core drastically increases coolant volume and surface area compared to stock units. Combined with aluminum's superior heat conductivity, it dissipates heat much more effectively. This prevents engine overheating, protects your transmission from heat damage, and allows your truck to maintain power and operate reliably when working its hardest.
    Q: Why is this all-aluminum radiator a better choice for my heavy-duty truck?
    A: Durability is critical for a work truck, and this radiator is built for it. It features 100% TIG-welded aluminum construction. Factory radiators on these C/K trucks use plastic tanks crimped to an aluminum core. These plastic tanks are the primary failure point, cracking under the constant stress and heat of heavy-dury use. Our full aluminum radiator eliminates this weak point, providing a much stronger, more robust unit that can withstand the vibrations and pressure of a working vehicle for years to come.

      Do you still make thermostats? / Can you make me a thermostat?

      We sold the portion of the company that made thermostat in December 2017. We no longer make, service, or troubleshoot them. Chandler Autosport bought us out and is no longer in business as far as we know unfortunately.

      My tracking number doesn't work!

      1. Label & Tracking Initiation:
      Shipping labels are generated only after orders are fully packaged, weighed, and sealed to ensure accuracy. Tracking updates depend on the carrier's initial scan during pickup. Occasionally, delays occur if the driver fails to scan the package upon collection, which may result in no tracking updates until the delivery stage.

      2. Delivery Assurance Protocol:
      While un-scanned packages rarely go missing, we advise allowing up to two weeks from the shipment date for delivery completion before escalating the issue. This grace period accounts for potential carrier processing delays.

      3. Lost Package Resolution:
      If your package remains undelivered 14 days after the shipping date, contact us immediately at Sales@gearacing.com. We will initiate a carrier investigation and arrange a replacement if necessary.

      check_box

      My tracking shows as delivered but I don't have it!

      If your tracking status indicates "delivered" but the package hasn’t arrived, rest assured this is typically a temporary discrepancy. In most cases, the carrier may have delivered to a neighboring address or marked the package prematurely while it remains in transit for final delivery within 1-2 business days. We recommend first contacting your local carrier depot to request GPS verification of the delivery location or confirm if the package is still en route. Simultaneously, check with neighbors, building staff areas.

      Many tracking updates resolve automatically within 48 hours as carriers finalize deliveries. If the package remains missing after this window, email Sales@gearacing.com.

      I want to change an item on my order that hasn't shipped

      Regrettably, we cannot modify orders once submitted due to stringent warehouse protocols designed to ensure accuracy and efficiency. With hundreds of orders processed daily, locating and altering individual packages would require halting production lines for disassembly, adding significant delays and operational risks.

      To resolve this, we offer a streamlined exchange process:

      Initiate a Return: Email Sales@gearacing.com to request a Return Material Authorization (RMA) form.

      Ship the Item: Return the original product at your expense using your preferred carrier.

      Replacement Process: Upon receipt and inspection, we'll expedite your replacement order.

      Note: Customers assume responsibility for return shipping and package safety during transit.
