Frequently Asked Questions: OE 13090805-00
How do I know this coolant expansion tank fits my Qin PLUS EV?
Match it by the OE number, 13090805-00, rather than the model name on its own. Find that number stamped or printed on the tank you are removing and set it against this listing before you order. The model and model year shown on your registration document will help narrow things down, but the OE number is what confirms the match. If the numbers agree, order with confidence. If you cannot find or read the number on the old part, hold off ordering until you can, or check it against the fitment table on this page.
What if the number on my old tank does not match this OE number?
Go by what is stamped or printed on the tank you are removing, not by the fault or the model alone. Look on the tank body itself for the OE number and compare it directly against 13090805-00 shown here. If the two do not match, this is not the right listing for your car, even if everything else looks similar. Fitment on EV thermal management parts is tight, so do not fit it on the strength of a general match. Find the marked number first, then order against it.
When will my battery coolant expansion tank arrive?
Allow 8 to 14 days for delivery, counted from your order to your door. When it arrives, check the parcel for damage before you sign for it, so any issue from the journey is flagged straight away. Once you have it out, hold it against the old tank you removed and compare the fittings and hose spigots before fitting the new one. If anything looks different, use the quote route on this page and check the OE number against 13090805-00 before you go any further.
Where does this expansion tank sit under the bonnet?
It sits in the engine bay, as part of the coolant valves and lines for the battery thermal management system. If you are trying to confirm which component you are looking at, this part is also listed under the reference SCEG-8111600, which can help when comparing against what you see fitted or what a workshop has quoted using a different code. Matching that alternative reference against your own part is a useful cross check before you order.
Is there a cheaper aftermarket option for this tank?
No, only the original, genuine BYD version is available for this OE number at present. An aftermarket alternative is not currently shown, but one can be found and priced for you on request. If you would prefer to compare options before deciding, use the quote route on this page and ask for an aftermarket alternative to be sourced against your OE number, and we will come back with pricing for you.
