Coolant Reservoir for 2013-2018 Dodge Ram 6.7L Diesel Coolant Overflow Tank | SPELAB

The factory plastic reservoir on your Dodge Ram 6.7L Diesel often turns brittle, cloudy, and leak-prone over time. SPELAB’s upgrade is a direct-fit replacement, made from TIG-welded 6061 aluminum for maximum strength and durability.

Why Upgrade to SPELAB?

SPELAB’s 6061 aircraft-grade aluminum coolant reservoir is TIG-welded and pressure-tested to deliver unmatched durability and leak resistance. Unlike stock plastic tanks made from two sealed halves, our one-piece aluminum design eliminates common failure points like cracking and seam separation.

Key Features:

Premium 6061 Aluminum – Stronger and more heat-resistant than OEM plastic
TIG-Welded Construction – Ensures long-term reliability under pressure
Sight Glass Window – Easily monitor coolant levels at a glance
Internal baffles— help prevent cooling system starvation and air pockets
Improved Heat Dissipation – Helps manage engine temperature more efficiently

    Good quality

    Only issue is it’s saying coolant low when it’s full
