CRP Engine Coolant Thermostat Housing

CRP Engine Coolant Thermostat Housing Assemblies

When an engine's cooling system starts to fail, a cracked or leaking thermostat housing is often the culprit. CRP has built its reputation over decades as a trusted source of OE-quality replacement parts for import and domestic vehicles, and their engine coolant thermostat housing lineup is a strong reflection of that commitment. With 22 part numbers in the catalog, CRP covers a wide range of applications — from Volkswagen Jetta and Passat platforms to Volvo, Audi, and beyond.

The Rein Automotive Standard

CRP Automotive offers premium replacement parts for import and domestic vehicles through trusted brands including Rein, AAE, Pentosin, and Ajusa. Their thermostat housing assemblies fall under the Rein Automotive banner, a sub-brand specifically focused on European-standard replacement parts. Rein Automotive OE-quality thermostat assemblies install, fit, and perform the way the original manufacturer intended — ensuring a smooth and easy installation, just as one would expect to find with OE quality.

These assemblies are designed to provide the professional repair technician and vehicle owner peace of mind, matching original equipment design specifications, allowing direct fitment for easy installation, and manufactured to strict engineering standards in materials and tolerances — made by the OE manufacturer.

Part Numbers & Coverage

CRP's thermostat housing assemblies span a variety of temperature ratings and vehicle fitments. For example, the CTA0012 targets an 80°C opening temperature for five-cylinder Volkswagen applications, while the CTA0013 is rated at 92°C for related platforms. The CTA0017 is engineered for Audi engines (cross-referencing OE number 06E121111AL) with an 85°C start-to-open temperature and includes a gasket or seal. Grade type is standard replacement, and gasket or seal is included where specified. Meanwhile, the CTA0018 and CTA0037 round out coverage for additional European nameplates, including Volvo applications.

CRP Automotive has also designed direct-fit aluminum upgrade housings — such as the HEU0116, which replaces the factory plastic housing on BMW B58 engines to address a recognized service failure point. This kind of proactive engineering approach sets CRP apart from purely commodity replacement suppliers.

OEM-Grade Quality & Warranty Coverage

With a focus on precision engineering, durability, and reliability, CRP delivers a wide range of products designed to meet the needs of various vehicle makes and models — from engine components and cooling system parts to belts, hoses, and gaskets — offering reliable solutions that meet or exceed OEM standards.

CRP products are covered by a Limited Warranty, during which products are warranted to be free from defects in material or workmanship. The warranty period begins on the date the product is delivered and is granted to the end-user for products purchased, installed, and used for their originally designed purpose. It covers defects arising under normal use, and during the warranty period, CRP will repair or replace, at no charge, any product defective in materials or workmanship.

CRP Industries Inc. is ISO 9001:2015 certified with TÜV Rheinland of North America , reinforcing the rigorous quality standards behind every part that leaves their facility. For enthusiasts and professional technicians alike, CRP's thermostat housing assemblies represent a reliable, direct-fit solution that stands up to the demands of modern engine cooling systems.
