Frequently Asked Questions: OE 12254978-00
The old shield has a different code on it. Am I looking at the right page?
Compare it with both of our references before you decide. This bonnet heat shield carries the OE number 12254978-00 and also as SCF-8402021. Either of those confirms the listing. Markings on a soft insulating panel are often printed rather than moulded, so they fade with heat and age, and a partial reading is common. If what you can see matches neither reference, send the visible characters and your vehicle details through the quote route and we will match the shield to your car properly.
How long before this is delivered?
Delivery time is confirmed with your quote. Since this is a trim item rather than something that stops the car being driven, most buyers order it and carry on using the vehicle. If you need a closer estimate, ask through the quote route with OE number 12254978-00. The shipping cost is confirmed with your quote.
How does a panel this large get to me?
It ships as an oversized but very light parcel. The packaging details are shown on this page. That does not post through a letterbox and it will not fit in a small car boot, so arrange for somebody to receive it. Keep it flat once it arrives, because a shield of this kind is easier to fit if it has not been folded or leant against a corner.
What is this heat shield made of?
Foam, which sits under insulation rather than structural panels. Foam is light and easily marked, so handle the new shield by its edges and keep it away from oil while the bonnet is open. It will not tolerate being creased into shape during fitting. No service life or replacement interval is published for the material, so change it when its condition tells you to. Check OE number 12254978-00 against the fitment table on this page before ordering.
Where is this shield fitted?
In the engine bay, at the front of the car. That means it is reached with the bonnet raised and no lifting equipment is needed to see it. We do not publish a clip layout or a fitting order for the panel, and the arrangement varies between vehicles, so work from what comes off your own car. Have the OE number 12254978-00 to hand when you speak to a garage, and check the fitment table on this page first.
Why is there only one option for this shield?
Only the Original/Genuine version has been listed, made by BYD. Nothing has been priced in the Aftermarket tier for this application. When both tiers exist for a part, they are shown priced together on the page, so a single option here is a statement about supply rather than about quality. If you would like us to look into alternative references, send OE number 12254978-00 with your vehicle details through the quote route and we will come back to you.
