Coolant Expansion Tank for BYD Seal 07 & Tang DM-i, OE 13319111-00

Fit is confirmed by matching your vehicle against the fitment table on this page, not by comparing the shape of the tank to the one in your engine bay. This tank sits in the Cooling System, among the Hoses, Tanks and Sensors, fitted in the engine bay, but that on its own does not tell you it suits your exact model. Check the OE number on your old tank against the fitment table before ordering, or send a photograph of the old part and its label through the quote route on this page so it can be confirmed against the OE number.

If the number on your old tank does not read 13319111-00, treat that as a mismatch rather than a close enough match. Look for the number stamped or moulded onto the tank you are removing and read it carefully, since a single digit out is still a different tank. Check that number against the fitment table on this page before you order, rather than against the OE number alone. If the two still do not agree, it is the number on your old part that should decide what you buy, not this listing.

Delivery time is confirmed with your quote. Once it is unpacked, hold it next to the tank you have taken off the Seal 07 or Tang DM-i and compare the two before fitting, rather than assuming the shape is right. If you have any doubt once you have compared them, use the quote route on this page to confirm the OE number before you go ahead.

This is a plastic tank, so look at how the old one attaches before you order. Check which side of the engine bay it sits on, what angle it mounts at and how many fixings hold it in place, then match that against the new one when it arrives. Getting the position and fixings right matters more than anything else with a moulded tank, since a plastic housing takes the shape it was made in and nothing more. If you are at all unsure of the layout, look at the fitment table on this page before ordering.

In terms of location, this sits in the engine bay as part of the cooling system, listed under Hoses, Tanks and Sensors on this page. If you are checking against an old invoice, a parts list, or packaging rather than this page, it may appear under its other reference, STHR-1311010, so look for that number too when confirming location and match. Matching either reference to your own paperwork is enough to confirm you have found the right tank for where it sits on your car.
