Coolant Expansion Tank for BYD Seagull, OE 13425972-00

Check the number stamped on the part you are removing before you fit this one. This tank is listed under OE 13425972-00, with EQEA-1311010 as an alternative reference, so look for either figure on the old tank. If what you find does not match, this is not confirmed as the right tank for your car. Take both numbers with you or note them down when you check, so you are matching what is actually stamped on the part rather than working from the car model alone.

Delivery time is confirmed with your quote. When the parcel arrives, check it for any obvious damage to the box before you sign for it, since that is easier to sort out at the door than afterwards. Once you have it in hand, compare it against the old tank you are replacing to be sure the shape and fittings line up. If anything about the fit looks uncertain, use the quote route on this page before you fit it.

This tank is made of plastic, built to the shape of the original BYD part under OE number 13425972-00. Have a look at the photographs on this page before you order, so you can compare the neck, the cap and the hose spigots against what is fitted on your car. A moulded tank like this only fits one way round, so matching it by eye first, alongside the OE number on the old part, helps you avoid ordering the wrong shape for your Seagull.

In the engine bay is where this tank sits, though the exact side, position and fixings depend on your own car. Look at where your current tank sits, how it is mounted and which hoses connect to it before ordering, since the fitting detail is not something a category or model name can tell you. Note the bracket or clips holding it, the side it sits on and the hose connections before you take the old one out. That way you fit the new tank exactly where the old one was, without extra checking once it arrives.
