Product details
Description
The Formula Auto Parts CTS5 Coolant Temperature Sensor is an essential engine management component designed to monitor operating temperatures and relay precise data directly to your vehicle control unit. Crafted to meet original equipment standards, this reliable sensor features a brass threaded body that screws securely into the engine block or intake manifold, along with an integrated sealing thread to prevent fluid leaks.
The exposed bullet-shaped tip houses a sensitive thermistor that continuously alters electrical resistance as coolant temperatures fluctuate. This vital feedback allows the engine computer to dynamically manage fuel delivery, air-to-fuel ratios, ignition timing, and electric radiator fan operation.
Replacing a failing or sluggish temperature sensor helps resolve issues such as rough idling, unexpected engine overheating, black smoke, and poor fuel economy. Engineered for durability and long service life, this aftermarket solution provides dependable performance for compatible vehicle applications.
How to use
- Ensure the engine is completely cool before starting installation.
- Locate the existing coolant temperature sensor on the engine block or intake manifold.
- Disconnect the electrical wiring harness connector carefully.
- Unscrew the old sensor using a proper socket and clean any debris from the mounting port.
- Thread the new Formula Auto Parts CTS5 sensor into place and tighten securely to avoid leaks.
- Reconnect the wiring harness securely, check coolant levels, and test the engine operation.

FAQs
What is a CTS sensor on a car?
A Coolant Temperature Sensor (CTS) is an automotive device that monitors the thermal condition of the engine coolant. It converts temperature changes into an electrical signal sent to the engine control unit to optimize fuel efficiency and ignition.
Where is the CTS coolant temperature sensor usually located?
The coolant temperature sensor is typically located near the thermostat housing, cylinder head, or intake manifold where it has direct contact with the engine coolant flow.
What happens if a coolant temperature sensor is bad?
A failing coolant temperature sensor can cause incorrect data transmission to the engine computer, leading to symptoms like rough idling, engine overheating, black exhaust smoke, and significantly reduced fuel economy.
Are the imported automotive parts on Dropy authentic USA imports?
Yes, Dropy sources all its specialty products directly from authentic USA markets to ensure you receive genuine quality items for your vehicle maintenance needs.
How to check if a coolant temperature sensor is faulty?
You can check a faulty sensor by scanning for diagnostic trouble codes using an OBD-II scanner, testing sensor resistance with a multimeter across various temperatures, or inspecting the electrical connector for corrosion.
