Motorad 5475-190 Engine Coolant Thermostat

Motorad UltraStat 5475-190 Thermostat Overview

Motorad UltraStat 5475-190 is an engine coolant thermostat built for OE-spec 190°F temperature control in select Volkswagen and Audi applications. It uses heavy-gauge stainless steel construction for corrosion resistance and long service life, with BLVT valve technology to reduce thermal shock in the cooling system.

Compatible with Volkswagen Jetta, Golf, Beetle, Passat, and Audi A4, A4 Quattro, TT, TT Quattro, A3, and S3 applications, this thermostat supports stable coolant regulation for daily driving and temperature consistency. The Motorad 5475-190 is a direct-fit cooling system service part for vehicles that require a 190°F thermostat setting.

Detailed Description

The Motorad UltraStat line focuses on durable thermostat construction and controlled coolant flow. Part number 5475-190 is engineered for vehicles that call for a 190°F thermostat, helping maintain the factory temperature range specified for many Volkswagen Jetta and Audi TT applications. Its stainless steel design resists corrosion, while the valve design helps moderate temperature changes as the cooling system cycles.

This part cross-references Monroe Shocks & Struts (e.g., 46419, 95475190) for the same application. Use Motorad 5475-190 when servicing cooling systems on compatible Volkswagen Golf, Jetta, Passat, Beetle, and Audi A4 platforms that require OE-style 190°F thermostat operation.

What It Helps Address

• Engine running cooler or hotter than the specified thermostat range
• Slow warm-up after cold starts
• Temperature fluctuation during normal driving
• Cooling system stress from abrupt thermal changes
• Thermostat replacement during routine cooling system service

Installation Notes and Tips

Confirm the OE-specified temperature before installation and verify housing and flange dimensions against the original thermostat. Because no gasket or seal is included, reuse is not recommended unless the sealing surface is confirmed serviceable and the correct seal is sourced separately. Inspect the cooling system for contamination, coolant condition, and housing wear before reassembly.
