    Common Questions

    Q: Will this radiator fit my 2002 Cadillac DeVille with the 4.6L V8? What about the AT/MT designation?
    A: Yes, this 3-row aluminum radiator is specifically engineered to fit the 2000-2005 Cadillac DeVille and the 2001-2003 Oldsmobile Aurora, but only models equipped with the 4.6L Northstar V8 engine. These vehicles were factory-equipped with an Automatic Transmission (AT), and this radiator includes the essential integrated cooler ports for it. The "MT" designation indicates it can be used in custom manual transmission swap projects, but it is designed for a perfect fit in the standard automatic cars.
    Q: How does this 3-row radiator help with Northstar V8 overheating issues?
    A: The 4.6L Northstar V8 is a high-performance engine notorious for generating significant heat, which often overwhelms the stock single-core radiator. This 3-row aluminum radiator is the most effective solution. It dramatically increases the coolant capacity and heat dissipation surface area. This allows it to easily manage the engine's heat load, preventing the overheating that can lead to costly head gasket failure and other serious engine damage. It provides the cooling headroom your Northstar V8 needs to run reliably.
    Q: How difficult is the installation on an Oldsmobile Aurora or Cadillac DeVille?
    A: Due to the transverse V8 engine layout and tight engine bay of the Aurora and DeVille, installation is more complex than on a typical rear-wheel-drive vehicle. While it is a direct-fit part with no modifications needed, we generally recommend professional installation for this radiator. A mechanic familiar with the GM Northstar platform will ensure everything, including the specific hoses and transmission lines, is connected correctly without issues.
    Q: Is this all-aluminum radiator a permanent fix for the common DeVille radiator leak?
    A: Yes. The most common reason for radiator failure in the Cadillac DeVille and Oldsmobile Aurora is the original design, which uses plastic side tanks crimped onto an aluminum core. These plastic tanks inevitably become brittle with age and crack under the Northstar's high temperatures. Our radiator is constructed from 100% TIG-welded aluminum, completely eliminating this plastic weak point. It is a robust, one-piece unit designed to be a durable, long-term solution to prevent leaks and protect your engine.

      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.
