Evaluate coolant odors, wet carpet, fogging, poor heat, or leaks that may involve the heater core.

Heating & Cooling

Heater core replacement

Heater-core symptoms can overlap with other cooling-system, airflow, and HVAC concerns. Diagnosis should confirm the source before major disassembly.

Apex can inspect the issue and discuss repair availability based on the vehicle.

Signs you may need this service

  • The temperature gauge reads higher or lower than normal
  • You notice a sweet odor, steam, or colored fluid beneath the vehicle
  • Cabin heat is inconsistent or the low-coolant warning appears

What you can check first

  • When the engine is fully cold, check the coolant reservoir level against its markings
  • Look beneath the parked vehicle for fresh drips without touching hot components
  • Note when the temperature changes occur, such as at idle, on the highway, or with the AC running

Only perform checks you can complete safely. Stop driving if the vehicle feels unsafe, overheats, loses braking, or shows a critical warning.
