Review on Reservoir Expansion Replacement 2009 2012 164700T040 by Shane Hartford

Excellent replacement parts, fit exactly as OEM. However, note two things: 1) Unlike OEM, this product does not have metal grommets in the screw holes. So reuse them from the old tank and make sure the mounting tabs are supported, otherwise there is a risk of increasing the frequency of product failures, and 2) the design of the tank opening and lid will be slightly modified (a bit more than OEM ). The new tank cap is only compatible with the same brand, so keep the cap and tank together. Do not mix aftermarket parts with original equipment coolant overflow parts.
