Keep your engine cool and your engine bay neat with a new Coolant Overflow Reservoir from T.I. Performance. Browse our range of coolant overflow bottles and expansion tanks to find the best fit for your vehicle.
The coolant overflow bottle is a critical component of your vehicle’s thermal management, allowing for the natural expansion and contraction of coolant fluid. We have a range of high quality replacement coolant tanks designed to withstand the high pressures of performance cooling systems. Our tanks are manufactured from UV stable, heat resistant materials to prevent the common “splitting” and “browning” seen in aged factory units. Perfect for owners looking to refresh their engine bay or ensure their cooling system is track ready and leak free.
