Coolant Expansion Tank For Mercedes-Benz R320 R350 R500 W251 2006-2013 W/ Sensor

So your Mercedes is telling you it's thirsty?

Probably needs a new coolant tank.

This one's a direct fit for the R-Class, specifically the W251 and V251 models from 2006 to 2013.

That covers the R320, R350, R500, R550, and even the R63 AMG.

The tank itself is brand new, still in its plastic wrap.

It's made of plastic, white with a black neck, and it mounts in the front.

Important: this one comes with the sensor, but it does NOT come with the cap, so make sure you hang onto your old one or order a new cap separately.

It's a direct replacement, so you just pull the old one out and pop this one in.

The part numbers are 2515000049 and 25 15 0 00 049, so it's the right one.

And it comes with a 1-year warranty, just in case.

Easy fix for an annoying leak.
