Thermal Expansion Valve for BYD New e6 & Tang DM-i, OE 12138265-00

This valve fits a wide spread of BYD models and many individual build variants inside them, so a match on the model name alone is not enough to go on. Work from the fitment table on this page and find your exact model and build year. If you can reach the old valve, check the OE number 12138265-00 against the marking on the unit already fitted. Where your car is not shown, or the marking has worn away, send a photograph of the old part and its label through the quote route and we will confirm the right valve before you order anything.

Not necessarily wrong. This valve carries the OE number 12138265-00 and is also catalogued as e6H-8106100, so either reference can turn up on an old unit or on a supplier label depending on when it was made. If the number you are holding is one of those two, you are in the right place. If it is neither, do not assume one supersedes the other. Send a photograph of the old part and its label through the quote route on this page, so we can check the reference against the BYD listing before anything is ordered.

Allow 8 to 25 days for delivery, counted from your order to your door. The packaging details are shown on this page. If you are working to a fixed date, say so through the quote route before you order. The shipping cost for your country is shown on this page and confirmed at checkout before you pay. Before you order, check the number on your old part against OE 12138265-00.

This valve is made of metal. For a buyer that is mostly a handling point. A metal valve body will not soften or deform in a hot container on a long shipment, and it can be wiped down and inspected before fitting without much thought. It also gives you a solid surface to read a marking from, which helps when you are matching the OE number 12138265-00 against the unit already on the car. That does not describe the internal parts, so ask through the quote route if you need more than that.

This valve is mounted in the engine bay, so it is reached from above with the bonnet open rather than from under the car or from inside the cabin. That is worth establishing before you book any time in, because it decides what has to come off to get at the valve. This does not go further than the bay itself, so it will not tell you which corner of the bay or what sits over the top of it. Use the BYD service diagram for that, and confirm your model in the fitment table on this page.

Only the Original/Genuine version of this valve is offered here. No Aftermarket equivalent currently exists for OE number 12138265-00, so what you see is what we can supply. The unit is a new part built to the BYD reference. Where a second tier does exist for a part, both are shown on the same product page, so there is no other listing to go looking for. In the meantime, if an alternative matters to you, ask through the quote route with the OE number and we will tell you what exists.
