Front Coolant Temperature Sensor for 2007-2009 Jeep Grand Cherokee & More - Standard Ignition TS-604

Coolant Temperature Sensor

• As a global manufacturer of original equipment ignition products, we maintain complete quality control throughout the manufacturing process from componentry to finished product
• Delivers accurate, real-time readings of the coolant/antifreeze mix-protecting the engine from overheating and maximizing efficiency.
• Engineered for Reliability: Built for long-term use, this high-quality, direct-fit replacement restores lost functionality caused by wear, fatigue, or electrical failure.
• Factory calibrated to OE temperature set point ensuring dependable electrical contact and performance every time
• Helps to maintain optimal engine temperature in all driving conditions, even extreme heat or cold-for smoother performance and fuel efficiency.
• In design, we specify custom wax formulations that will expand when heated, activate a snap action electrical contact and transfer the electrical signal to the fan controller
• In manufacturing, we custom form the wax pellets for different temperature range specifications. All units are calibrated and tested to confirm switch actuation at their specified temperature
• In production, all thermal switches are factory-calibrated to make electrical contact at the specified lower-temperature set point
• Rigorously tested to ensure consistent, out-of-the-box reliability.
• Robust design and high grade materials meet the stringent demands of today's service professional
• 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
