Designed specifically for the auxiliary coolant reservoir/overflow tank. We strongly recommend test-fitting your Coolant Reservoir Cover prior to prep and paint.

Features & benefits

Lightweight aluminum construction — dissipates heat quickly and won’t rust.
Clean, show-car aesthetic — hides the OEM plastic tank for a cohesive engine-bay look.
Finish-ready — paint, powder-coat, wrap, or dip. If leaving the factory aluminum look, apply a light clear coat to prevent discoloration from handling oils.
Precision-formed for a snug, secure fit.
Downloadable PDF installation instructions included after purchase.

Material & construction

Crafted from aluminum for optimal weight, durability, and thermal performance in engine dress-up applications. Most parts feature a brushed finish; some covers may show minor mill marks on bent or welded areas—this is normal and typically hidden or minimized once finished.

Installation

Allow the engine to cool before working under the hood.
Test-fit the cover to confirm clearance for hoses and cap access.
Prep and finish (paint/powder/wrap) as desired, then install following the included instructions.
Basic hand tools recommended. Do not obstruct the reservoir cap or vent path.
