Engine Coolant Temperature Sensor Replacement in Orlando — Fix Overheating, Hard Starts & Poor Fuel Economy
Your engine coolant temperature (ECT) sensor tells the computer how hot the engine is. It uses this information to control fuel mixture, ignition timing, cooling fans and even the temperature gauge. When the sensor fails, you can get hard starting, high fuel use, fan problems, overheating or a false temperature reading. At Top Notch Mobile Repair LLC, we provide mobile engine coolant temperature sensor replacement in Orlando, diagnosing and fixing these issues right at your home or office.
What Our Engine Coolant Temperature Sensor Replacement Service Includes
- Scanning the engine computer for temperature-related and mixture-related trouble codes
- Checking live data to compare actual coolant temperature vs. sensor reading
- Inspecting the ECT sensor connector and wiring for corrosion or damage
- Verifying coolant level and overall cooling system condition
- Removing the faulty coolant temperature sensor from the engine or housing
- Installing a quality, vehicle-specific replacement ECT sensor
- Topping up coolant if needed and bleeding any air from the system (where applicable)
- Clearing codes and performing a road-test to confirm proper readings and fan operation
We make sure the sensor is actually the problem — not just replacing parts blindly.

Affordable Engine Coolant Temperature Sensor Replacement Cost
Replacement cost depends on:
- Your vehicle’s make and model
- Sensor location and how much access/disassembly is required
- Whether additional cooling system work (coolant change, thermostat, leaks) is needed
Before replacing the sensor, we will:
- Explain your codes and live data readings in simple terms
- Show you any wiring or connector problems we find
- Provide a straightforward estimate for the sensor and labor
No guesswork — just proper diagnosis and targeted repair.
Common Signs You Need Engine Coolant Temperature Sensor Replacement
- Check engine light with coolant temp or mixture-related codes
- Temperature gauge reads cold all the time, or jumps around erratically
- Cooling fans running constantly, or not turning on when they should
- Hard starting, especially when the engine is cold or hot
- Poor fuel economy and rich running (strong fuel smell, black tailpipe soot)
- Engine seems to overheat but the gauge doesn’t match what you see/smell
Because the ECT sensor affects fuel mixture and cooling fan control, a bad reading can cause driveability problems and even engine damage if ignored.
💡 Pro Tip
If your gauge always reads cold, or fans run nonstop, don’t assume it’s “just the gauge.” The coolant temperature sensor feeds the computer, not only the cluster. A wrong reading can make the engine run too rich or too lean and cause long-term issues — fixing it early protects your engine and your fuel budget.
