C190C Code - Rear Metal Board Overheat

Quick Answer

The diagnostic code C190C indicates that the rear metal board in the vehicle is overheating. Common causes include Malfunctioning cooling fan: A faulty cooling fan can fail to cool the rear metal board efficiently, leading to overheating, Clogged radiator: A clogged radiator can restrict coolant flow, causing the rear metal board to overheat, Faulty thermostat: A malfunctioning thermostat can prevent the coolant from circulating properly, leading to overheating. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code C190C Description

The diagnostic code C190C indicates that the rear metal board in the vehicle is overheating. The metal board is a crucial component in the vehicle's cooling system, responsible for dissipating heat generated by the engine and other systems. When the rear metal board overheats, it can lead to a variety of issues that can affect the vehicle's performance and potentially cause long-term damage if not addressed promptly.

Common Causes of C190C

  1. Malfunctioning cooling fan: A faulty cooling fan can fail to cool the rear metal board efficiently, leading to overheating.
  2. Clogged radiator: A clogged radiator can restrict coolant flow, causing the rear metal board to overheat.
  3. Faulty thermostat: A malfunctioning thermostat can prevent the coolant from circulating properly, leading to overheating.
  4. Low coolant levels: Insufficient coolant in the system can cause the rear metal board to overheat due to a lack of cooling capacity.
  5. Water pump issues: A failing water pump can result in poor coolant circulation, contributing to rear metal board overheating.

Symptoms of C190C

  1. Engine overheating: The most common symptom of a rear metal board overheating is the engine running hotter than normal, potentially leading to overheating.
  2. Reduced cooling efficiency: The vehicle may struggle to maintain optimal cooling levels, leading to poor performance in hot weather or during long drives.
  3. Increased fuel consumption: An overheating rear metal board can cause the engine to work harder, resulting in increased fuel consumption.
  4. Warning lights: The vehicle's dashboard may display warning lights related to the cooling system or engine temperature, indicating a potential issue.

How to Fix C190C

  1. Check coolant levels: Ensure that the vehicle has sufficient coolant and top it up if necessary.
  2. Inspect cooling fan: Check the cooling fan for proper operation and replace if needed.
  3. Flush radiator: Flush the radiator to remove any clogs or blockages that may be causing overheating.
  4. Replace thermostat: Replace the thermostat if it's faulty and preventing proper coolant circulation.
  5. Test water pump: Test the water pump for proper functioning and replace if necessary.

Cost to Fix C190C

The typical repair costs for addressing a rear metal board overheating issue can vary depending on the specific cause and the extent of the damage. On average, the repair costs can range from $200 to $500, including parts and labor. It's important to note that labor rates at auto repair shops can vary, with hourly rates typically ranging from $80 to $150. Additional costs may be incurred if other components in the cooling system need to be replaced or repaired. It's advisable to consult with a professional mechanic to get an accurate estimate for the repair.
