I was told a heater core flush was my last resort before getting the heater core replacement. The drive from Mississauga was well worth it, these guys are specialized and know their stuff.

It was odd that the dealership referred me to an independent mechanic for no heat. I’m sold now, these guys are not only helpful and friendly, but they saved me A LOT of money. Highly recommended.

I cannot say enough good things about this shop. They go out of their way to make sure you are well informed and are very honest. I recently had an issue with brakes which could have cost several hundreds of dollars. They troubleshot and found that it only was a small problem. They even charged me only for the parts and brake fluid actually used, other shops always charge full bottle and would have suggested unneeded additional parts/services.When I picked up the vehicle, they gave me a complete run down of what happened and why and then identified potential future issues and recommendations for the vehicle.The most professional repair shop I have ever been to. Would not hesitate to recommend this shop to family and friends!

After owning numerous vehicles in over 30 years and taking those vehicles to a lot of different repair shops including the dealer, I finally was fortunate to get referred by a friend to these guys. WOW, they are amazing! First of all, they are by far the most honest shop I have ever taken my vehicle to in my entire life. The work was spot on and the price was fair. I had some other things I needed to do the car that were not urgent and they were kind enough to recommend waiting until spring time to do it (which would save me money), Wow, most shops try to milk every penny out of you any time they see you, not these guys. Honest and great work, Highly recommend.

No heat in your Nissan, needs a heater core flush

What’s a Heater Core – No Heat in Your Nissan

  • What is it? A heater core functions similarly to a radiator. It circulates hot coolant to provide warmth inside the car’s cabin. If blocked it causes no heat in your Nissan.
  • What are the symptoms?
    • Heating: If your car struggles to warm up the cabin…
    • Strange Noises: Gurgling or bubbling sounds from the dashboard…
    • Overheating: Your car overheats despite adequate coolant…
  • What’s a professional heater core flush?
    • As mechanics, we diagnose the cause (which isn’t always the core)
    • Comprehensive check of entire cooling system, identify any leaks
    • Inspect coolant and replace if necessary
    • Heater core flush using specialized equipment (chemicals if necessary)
  • Benefits
    • A heater core replacement isn’t needed
    • No engine overheating
    • Resolves no heat in your Nissan
    • Prolonged life of the heater core
    • Optimal functioning of the cooling system
  • Maintenance. Performing regular coolant changes (and flushes as needed) will prevent these issues.

Customer Education

Our service goes beyond just providing a heater core flush. We believe in educating our customers about the importance of regular vehicle maintenance. Our experts are always ready to share valuable insights and tips to help you maintain your vehicle’s health. We’re the specialists for no heat in your Nissan, see us first.

What Clogs the Heater Core?

  • Coolant: The coolant can become acidic and start to break down, picking up debris, rust, and sediment from the engine and radiator.
  • Scale and Rust Formation: Formation of scale and rust inside the cooling system.
  • Low Coolant Flow: Low coolant levels or poor circulation can cause sediment to settle in the heater core.
  • External Debris: External debris like leaves or dirt entering the cooling system.

Other Related Parts – No Heat in Your Nissan

As professional mechanics, we understand the heater core flush may not be needed. We may also diagnose the following when there is no heat in your Nissan:

  • Low Coolant: may not be able to circulate through the heater core effectively.
  • Thermostat Failure: Regulates the flow of coolant.
  • Trapped Air: Air pockets in the cooling system can impede the flow of coolant.
  • Water Pump: The water pump circulates coolant throughout the engine and heater core.
  • Heater Control Valve: If the heater control valve is stuck, blocked, or broken, it can prevent hot coolant from entering the heater core.
  • Faulty HVAC: Issues with the vehicle’s HVAC (Heating, Ventilation, and Air Conditioning) lead to a lack of heat.
  • Heater Hoses: If hoses that carry coolant to and from the heater core are damaged, kinked, or blocked, they can restrict coolant flow.
  • Electrical Issues: Problems with the vehicle’s electrical system.
  • Blend Doors: Blend doors within the HVAC system control the mix of hot and cold air.
  • Low Engine Temperature: If the engine isn’t reaching the proper operating temperature, it won’t provide heat to warm the cabin.
  • Exhaust System: Although less common, an exhaust system leak near the heating system can draw heat away.
  • Radiator Cap: A radiator cap that doesn’t maintain the proper pressure.
  • Coolant: Using the wrong type of coolant or mixture.
  • Wear: General wear and tear can affect various components of the heating system.

Final Thoughts – No Heat in Your Nissan

A heater core flush may not resolve no heat in your Nissan if it’s something else. Coolant also contributes to the heat in your car. A heater core replacement is very pricey. Performing regular coolant changes (and flush if necessary) will prevent such inconvenience. If you’re experiencing no heat in your Nissan, Radman Auto Repair is your best option.
