car overheating, coolant bottleIs your car overheating? There could be lots of reasons for that! Before you get out your toolbox, learn more about why your car might be overheating! There are a few quick things you can check to see if your car is overheating for an obvious reason, but there is one reason your car may be overheating that is very difficult to diagnose.

If your vehicle’s cooling has simply lost efficiency everything could look perfect from the outside but inside the cooling system, you’ve got big problems. Assuming you’ve got all the coolant you need there are a few things that can cause inefficiency in your cooling system.

Cooling System Inefficiencies that Could Cause Your Car Overheating

  1. External Radiator Clogging or Damage
  2. Scale on your Block
  3. Corrosion Particle Build Up
  4. Clogged Radiator or Heater Core

Even though flushing your radiator won’t help with extremal problems, we thought it was worth mentioning!  If your car has air conditioning, check for dirt or leaves etc. stacked up in between your A/C condenser and your radiator.  Also check to make sure any air ducts, plastic shields or other devices that help force air through your radiator are in place.  Lastly, check your radiator cooling fins to see if they are bent or damaged restricting air flow.

One of the only ways to remove block scale is to perform a radiator flush using a chemical cleaning agent like BlueDevil Radiator Flush.  While you run your engine with BlueDevil Radiator flush in your cooling system it will remove the scale on the cooling jacket on your block.  This scale works like an insulator and keeps the coolant from taking the heat away from your engine. With the scale gone your engine will run much cooler!

Like every system in your car, corrosion and wear products will build up over time.  If you don’t regularly flush your coolant you will get this build reducing the cooling area of your system leading to overheating.  These blockages love to happen in your car’s heater core which can really reduce cooling flow in your engine so make sure your flush your heater core forward and backward to remove these wear products before refilling your system with coolant.
