Coolant Expansion Tanks

IT’S ALL ABOUT COOLING.

Get comprehensive cooling system coverage for import vehicles with Rein Automotive’s Master Cooling Category.

Identical in form, fit, and function to the OE.

The Rein Master Cooling Category provides shops and technicians a full assortment of cooling system replacement parts for popular European vehicle applications. Replacement parts that are designed to fit and perform just like the orginals — which means fewer headaches for both technicians and vehicle owners.

Coolant Hoses

Coolant Hoses

Designed to be direct replacements for European OE hoses and assemblies, Rein hoses are 100% identical in form, fit, and function. So they fit import vehicles the way the original manufacturer intended. Which results in simpler, quicker repairs for the professional repair technician.

  • Rein hoses have the same number of branches in the correct sizes and locations as the OE hoses they are replacing — no unwanted surprises
  • If the OE hose has thermoplastic “Quick Connect” fittings, the Rein Automotive hose will also have these fittings — no more cutting hoses to fit or repurposing old fittings
  • Hose kits with the OE temperature sensor already pre-installed on the hose are available as well — no unnecessary extra steps
Coolant Expansion Tanks

Coolant Expansion Tanks

To better withstand the damage caused by exposure to thousands of heat cycles from the engine, our expansion tanks are fabricated from 100% virgin plastic (they don’t contain any regrinds). This stronger plastic prevents the tank from cracking and leaking prematurely, protects the engine from overheating, and ensures the tank’s long life in the cooling system.

In instances where a vehicle has overheated, the expansion tank, expansion tank cap, and coolant level sensor should all be replaced (as they may have been exposed to temperatures outside their operating range) — which is why we also offer expansion tank kits that include the tank, coolant level sensor, and cap.

Water Pumps and Kits

Water Pumps and Kits

CRP Automotive has worked closely with its Innovation Council to create a line of high-quality Rein Automotive water pumps technicians can be 100% confident in. The result is a partnership DOLZ, a worldwide leader in water pumps, to study the OE designs and make improvements recommended by professional repair technicians. All Rein/DOLZ water pumps are guaranteed to exceed even OE standards and are backed by an industry-leading 4-year/50,000-mile warranty.

  • All pumps match the OE design and materials for minimal thermal expansion and low noise
  • The internal seals are made of silicon carbide, for high-pressure resistance as well as noise reduction
  • Pumps come with OE-quality gaskets to prevent leakage after installation
  • We also offer several complete water pumps and water pump kits which include the thermostat assembly, temperature sensor, and/or hose (Some pumps offer the option of metal or plastic impeller as well.)
Thermostats and Thermostat Assemblies

Thermostats and Thermostat Assemblies

Rein thermostats and thermostat assemblies match the OE specs and temperature ratings, making them the go-to replacement parts when a cracked or failing one needs to be replaced.

Most modern thermostat assemblies are made using thermoplastic due to their tolerances of extreme heat inside the engine bay. Unfortunately, exposure to oil and other elements can cause then to fail over time. A failed thermostat can lead to decreased fuel economy, increased emissions, or worse yet, cause the engine to overheat.

Thermostats and thermostat assemblies should be routinely inspected and are often replaced as part of the maintenance procedure. Typically, they should be changed along with any water pump repair. Rein thermostats and thermostat assemblies match the OE specs and temperature ratings.

Caps

Caps

Caps are an often overlooked, but important, component in a vehicle’s cooling system. Cap locking mechanisms can fail or wear over time, which can cause fluid loss. Their valves can also fail, triggering a code.

  • When a cap gets damaged or fails due to wear and exposure, or is lost, a replacement from Rein will fit as perfectly as the OE.
  • Great selection of fuel, oil, and expansion tank caps
  • Because they are an exact match to OE specs they install easily and function properly
Temperature Sensors

Temperature Sensors

Having a durable and accurate exhaust temperature sensor significantly impacts an engine’s performance — maximizing fuel economy, minimizing emissions, and protecting the engine from overheating. Rein Automotive offers a trusted line of OE-quality exhaust sensors for Audi and Volkswagen 2009-2015 4 Cyl. 2.0 and V6 3.0L diesel engines used in A3, Q7, Beetle, Jetta, Passat, and Golf models that:

  • Accurately monitor the vehicle’s exhaust gas temperature with millisecond response times even at high gas velocities.
  • Enable the ECU to properly regulate exhaust gas after treatment systems and control the engine conditions to safely maximize an engine’s performance.
  • Are easy to install and come with the gasket and retaining clip, ensuring everything needed 
is included to complete the job.
