Really at my wits end with this car atm.

I originally changed the expansion tank with a eBay expansion tank. I have come to realise that most photos on Google show one O-ring on the bottom of the tank.

I’ve now had a second tank delivered with the eBay listing showing one O-ring. The part arrives with two O-rings.

Can anybody confirm a source where I can obtain a tank with a single O-ring?

or just something that fits 😭

at this point, I feel like it would be easier to replace the radiator with a built-in tank.

Has anyone been in the same situation?

Would appreciate any advice as always

thanks

Tyler
