Oe Solutions Series Coolant Reservoir
Thanks for Coolant Reservoir!
I'm bought this thing, and install it, and save $150.00
Purchased on Dec 07, 2016
the resevoir seems to be high quality, but it is white plastic instead of clear, so it's hard to tell the exact coolant level.
Purchased on May 20, 2013
I bought this thinking it was an OEM fit when in fact it wasn't. The 2002 audi coolant reservoir has tabs rather than screw holes. What I received was something that needed to be screwed in and i ended up having to use cable ties. Also, the cap leaks everywhere so I can't drive far and am spending more on coolant than gas.
