Hello.

My wife inherited a 95' SC400 with 95'000 last summer. It's a sweet ride I had no idea just how killer these cars were. It just ticked over 100k not long ago and shortly after having it detailed I noticed a huge puddle under it. Turns out it was coolant. As many other have, the expansion tank is leaking and finding one is next to impossible.

Besides spending $200 for a used one that is potentially problematic, or a new one that's $400+. Are there any other options I've missed? I've noticed while the car is running the tank is nearly empty. Do they make an aluminum replacement or perhaps a vendor here that has another solution? Thanks in advance.

$200 for a used tank? Post a WTB ad in the classified section here and see if you can get a replacement. Be careful not to overheat the motor in the meantime. Check the coolant level and burp the system.
