TITANIUM COOLANT RESERVOIR NISSAN GTR R35

Titanium Coolant Expansion Reservoir Tank | Nissan GT-R R35 VR38DETT

Engineering Overview

The factory translucent plastic coolant expansion tank on the Nissan GT-R R35 degrades, yellows, and becomes brittle after repeated engine bay thermal cycles—frequently leading to hairline cracking, high-pressure coolant leaks, and micro-air pockets within the VR38DETT cooling circuit—a critical point of failure eliminated by the Titanium Coolant Expansion Reservoir Tank, which is hand-fabricated from Grade 1/Grade 5 titanium sheet with high-purity TIG-welded seams to deliver complete immunity to thermal stress, a 50% increase in fluid expansion capacity, and a permanent high-pressure seal for extreme track and drag setups.
