Frequently Asked Questions: OE 12640664-00
How do I check this fits my car?
The badge on the boot does not settle which engine is in front of you, so read the fitment table on this page against your own car before ordering. This timing chain covers a wide set of BYD vehicles, and the entry that matters is the one matching your engine. Where you can still read the old chain or its bag, check for 12640664-00. If the table leaves you unsure, send a photograph of the old chain and its label through the quote route and we will tell you whether this is the correct chain for your car.
What if the number on my old part does not match?
Your old chain, or the packet it arrived in, may carry 476ZQC-1021100 rather than 12640664-00. Both point at this same timing chain. A number that does not match the title is therefore not a reason to close the page. Read whichever marking you can find and compare it with the two shown here. If you are still unsure, or the old chain is unmarked, send a photograph of the old chain and its label through the quote route and we will confirm it before you order.
How long before it is with me?
There are two parts to the timing. Allow 8 to 25 days for delivery, counted from your order to your door. If the window is too long, ask the quote route about the options. The shipping cost for your country is shown on this page and confirmed at checkout before you pay. Before you order, check the OE number on your old part against the one on this page.
What material is this and what does that mean for me?
Metal is the material used for this timing chain, and it is supplied new. Keep the wrapper on until you are ready to fit it, and check the OE number 12640664-00 printed on the packaging against the one you ordered. Anything that reads differently should be raised with us before the job starts.
Where does this chain sit on the car?
This timing chain sits in the engine bay, on the timing drive. That tells you where to look on your own car and where it is not: this is not an underbody or cabin part. Before you order, confirm that the chain you are replacing is the timing chain and not another drive chain in the same area, then match the OE number 12640664-00 where you can read it.
Why can I not choose a cheaper tier here?
This timing chain is offered in the Original/Genuine tier only, manufactured by BYD. No Aftermarket version exists for 12640664-00, so the price shown on this page is the single figure in play. If you would prefer an alternative source, or you are pricing a full engine job and want everything quoted together, send the OE number and a photograph of the old part through the quote route and we will come back to you.
