Our take on the Rein Engine Coolant Reservoir EPT0009

The Rein EPT0009 is a direct-fit coolant expansion tank for several Mercedes-Benz GL and ML models from the mid-2000s through 2012. Rein molds it from virgin plastic with no regrind, which it says resists cracking from heat cycles and lasts longer than the brittle factory tank it replaces. It suits owners of a GL320, GL350, GL450, GL550, ML320, ML350 or ML550 whose original tank has cracked or started seeping. Against a dealer tank it is the same OE-style fit at a lower cost, and against generic aftermarket tanks the virgin-plastic claim is the main difference.

Questions and answers

Which vehicles does the Rein EPT0009 fit?
It fits 2006-2011 ML350, 2007-2012 GL450, 2008-2012 GL550, 2009 GL320 Bluetec, 2010-2012 GL350 Bluetec and related ML320 CDI and ML550 models. Check your year, model and submodel against the fitment list before ordering.
Is this the same as the Mercedes-Benz factory tank?
Rein says it matches or exceeds the OE materials and installs and performs like the original. It is a direct-fit replacement, not a genuine Mercedes-Benz part.
Does it come with a cap?
The reservoir is the tank itself. Reuse your existing cap unless the listing states a cap is included.
Why do these tanks crack?
Factory tanks are exposed to constant heat cycles, and the plastic becomes brittle over time. Rein uses virgin plastic with no regrind to slow that process.
Can I install it myself?
Yes. It is a direct-fit tank, so installation is a matter of draining coolant, unclipping hoses and the mounting, and swapping the unit. Bleed the cooling system afterward.
Is it worth it over a cheaper generic tank?
The virgin-plastic construction and OE-style fit are the reasons to choose it. A generic tank may fit, but Rein's claim is longer service life under heat cycling.
Where is the Rein Engine Coolant Reservoir EPT0009 cheapest?
At FR SPORT, for $52.96, as of our latest check.
Where can I buy the Rein Engine Coolant Reservoir EPT0009?
