Frequently Asked Questions: OE 11973856-00
This fluid is listed against a lot of models. How do I confirm it suits mine?
Breadth of fitment is not the same as certainty, so check rather than assume. Open the fitment table on this page and find your own car in it by model and by year, because specifications differ inside a single model name. The other check is what your car already asks for, which is given on the vehicle and in its handbook. Where the table and your own car agree on the HZY6 specification you are safe to proceed. Where they do not, use the quote route on this page and give us the vehicle details.
My garage quoted me a specification rather than a long number. Does that match this?
It may do. This product answers to the OE number 11973856-00 and is also known as HZY6, which is the shorter reference a workshop is more likely to quote at you. If HZY6 is what you have been told to buy, this is the product you want. If the reference you were given is anything else, do not translate it yourself. Pass it to us with your vehicle details through the quote route on this page and we will check it.
Can I change this fluid myself, or should a professional do it?
This fluid is marked as critical to safety, and that mark exists for a reason. Braking is not an area to learn on, and the consequence of getting it wrong is not a rattle or a squeak. Our position is that the work belongs with a qualified technician who has the equipment to do it properly and to check the system afterwards. Buy the fluid here by all means, then have it fitted by someone competent. Check the OE number against the old part before your garage starts, so the right specification goes in.
How far ahead of a service should I order this?
Delivery time is confirmed with your quote. If your garage has pencilled in a date, count backwards from it using both numbers and order accordingly, rather than assuming the fluid will appear in the same week you ask for it. Booking the work first and the fluid second is the usual way people end up rescheduling. The quote route on this page can confirm timing if it is tight.
Is there an alternative brand of this fluid on the page?
No. Where two tiers exist we show Original/Genuine and Aftermarket beside each other so you can decide. This page carries the Original/Genuine product from BYD on its own, with no aftermarket alternative offered under the OE number. On a fluid marked as critical to safety, we would rather show nothing than show something we cannot stand behind. If you want the market checked for an equivalent, send your vehicle details and the OE number through the quote route and we will report back.
