2023 Audi S4 Cooling and Climate Controls

The product selection from Pierburg Pump Technology covers the complete range of applications for electric water circulation and coolant pumps in the automotive industry. Pierburg has extensive experience in the area of electric water pumps, especially with regard to EC engine technology and hydraulics. The canned motor concept was selected to meet the high requirements for operational reliability and service life. This special motor design has an additional tube placed in the space between the stator and the rotor, which keeps the stator statically sealed with respect to the medium pumped by the running rotor. Since this drive system requires no dynamic sealing elements which are subject to wear (rotating mechanical seals), the water circulation and coolant pumps are especially reliable and free of wear problems. Moreover, the EC motor used in the pumps requires no brushes. Eliminating the mechanical commutation system leaves the durability of the rotor bearings as practically the only limiting factor for service life. In addition to that, the lower number of moving parts results in significantly reduced noise.

Oil Drain Plug Gaske

Approved materials for increased durability in even the most extreme temperatures. All MotoRad Coolant Temperature Sensors are designed to meet or exceed OEM specifications at our ISO TS16949 manufacturing facilities.

Product Features:

• 100% factory resistance calibrated to ensure precision tolerances, resulting in extremely accurate temperature for optimal performance
• Thread Sealant and/or O-ring pre-installed on applicable sensors to ensure leak free performance
• Brass sensor housing precision machined to meet or exceed OE thermal conductivity
• OE precision matched thermistor position for correct output parameters
• Extensive product testing includes salt spray, high/low temperature impact, thermal vibration, durability, static electricity, and micro tension, among other tests, to ensure all sensors meet or exceed OEM specifications.

High-quality products that meet OE appearance and performance to provide professional technicians and DIYers with a cost-effective solution.

Product Features:

• Designed to OE standards for ease of installation
• In manufacturing, we custom form the wax pellets for different temperature range specifications. All units are calibrated & tested to confirm switch actuation at their specified temperature
• The switch is designed using a formed bimetallic contact arm. The bimetal contact movement is achieved using the different expansion rates of two metals fused together. This is a creep action device, provides precise performance
• In production, all thermal switches are factory-calibrated to make electrical contact at the specified lower-temperature set point
• Robust design and high grade materials meet the stringent demands of today’s service professional

The Engine Coolant Temperature Sensor determines the exact temperature of the engine coolant by sending an analog signal to the ECM to censure proper air/fuel ratio along with proper operation of the cooling fan(s) and temperature gauge. The Engine Coolant Temperature Sensor may be located on the cylinder head, engine block, thermostat housing or intake manifold. Reasons for replacement include: check engine light illumination, erratic or no temperature gauge operation, erratic or no cooling fan operation, and engine overheating.

Product Features:

• OE MATCHED: Wires and probe length match OE. Mounting clip(s) included where applicable
• FASTER RESPONSE TIME: Thermal conductive grease inside brass housing increases sensor response time
• THE NTK DIFFERENCE: Thread sealant/o-ring installed where applicable. Thermistor placement within the housing matches OE to ensure proper output. Proper thermal conductive grease to provide accurate temperature transfer to the thermistor
