Tanks & Caps

Coolant expansion tanks are an essential component of any cooling system. Like all Rein Automotive parts, our coolant expansion tanks are designed to fit and function just like the original part.

Our expansion tanks are manufactured from 100% virgin plastic to withstand the on-going impact of heat cycles from the engine. Using a more durable plastic prevents the tank from cracking and leaking prematurely, protecting the engine from overheating, and ensuring the tank’s long service life.

Tank caps are an often overlooked, but essential, component in a vehicle’s cooling system. Expansion tank caps regulate the pressure in the cooling system to ensure that, as the vehicle goes from cold to operating temperature, the pressure gets high enough to make the system function properly — while at the same time vents when needed to prevent overheating and damage to critical components. CRP Automotive offers expansion tank caps as well as fuel and oil caps, each guaranteed to work as correctly as the OE part.

To help you find the correct part or fluid for a specific application, CRP Automotive products are listed in an online catalog. Subscribers to Activant/Epicor, WHI, and other leading eCat platforms should also be able to find CRP Automotive parts on these e-catalogs.
