Cooling System And Radiator Repair

There are many parts of a vehicle’s cooling system. Each of these parts plays an important role in helping the overall functioning of the cooling system. Each works in sync with the others to keep your vehicle’s engine cool and running smoothly.

The main fluid responsible for this cooling process is the antifreeze. It is released whenever the thermostat under the hood detects that the engine is getting too hot. This begins the process whereby the antifreeze makes its way throughout the various parts it needs to cool until eventually arriving to the radiator where it is cooled off again, thus getting rid of the heat produced during driving.

Cooling System Repairs We Normally Handle:

  • Cooling fan
  • Water pump
  • Thermostat
  • Radiator
  • Heater core
  • Heater valve
  • Freeze plugs
  • Pressure cap

These are the parts of the cooling system that tend to fail most often and are the ones we take on. We conduct many more of these types of repairs during the summer time when these parts are really put under stress.

Antifreeze replacement

There are two major times we will work with antifreeze. When there is a leak or some other problem in the car that causes the antifreeze to drain away, or when the antifreeze has begun to lose its efficacy if not replaced frequently enough. Older antifreeze can cause corrosion within the cooling system.

The process for draining and removing antifreeze is straightforward. Doing so in accordance with your manufacturer recommendations will keep your car’s engine running cool, especially during those critical summer months.



Radiator Leak and Repair

The most common problem we encounter with radiators is leaks. If antifreeze begins to leak from the radiator, then the car will eventually start to overheat. The leaks will most likely occur around the radiator hose.

We can conduct a radiator pressure test in order to diagnose radiator damage. If you notice antifreeze leaking out from your car, then it is time to bring it to a certified mechanic. Leaving this problem alone for too long will cause overheating and possibly engine damage. As long as you pay attention to simple warnings that your car will give, you should be able to avoid expensive repairs.

Common symptoms of a failing radiator

  1. Coolant/antifreeze leaking underneath the car. Looks like a bright yellow or green fluid
  2. High temperatures reported by the car’s thermostat or overheating
  3. Radiator fins are filled with gunk. Also look for discolored radiator fluid
  4. Coolant levels are low.


Diagnostic Services:

We will perform a variety of inspections in order to check if you have problems with the cooling system. Our evaluation includes:

  • Performing a visual inspection
  • Checking for signs of overheating
  • Combusting leak testing
  • Check all fluids like transmission and oil
  • Test radiator cap pressure
  • Check for leaks using methods such as tracers

Leaks can be a tricky problem to tackle, especially if they occur internally within the combustion system of the car. It is important to always have certified mechanics who specialize in your vehicle’s type performing these types of evaluations. Otherwise, they may not catch every problem and you will find yourself coming back again to fix a problem that should have been dealt with the first time.


Coolant Flush:

The process for performing a flush is simple:

  1. Put flush chemicals in radiator
  2. Warm up the car
  3. Drain coolant
  4. Refill with water
  5. Repeat
  6. Fill radiator with water and fluid at levels according to manufacture guidelines
  7. Conduct inspection for leaks or damage

If you have a newer vehicle, then there will probably be sensors that will detect low coolant levels. The car’s electronics may then warn you that you need to have your fluids topped off. However, you should always check your owner’s manual for this information and on service intervals. You should have your vehicle routinely maintained, especially including the cooling system.


Cooling system parts:

Coolant: water and coolant combined is a fluid that absorbs heat and provides lubrication

Thermostat: regulates when coolant should flow through the vehicle

Water pump: moves the coolant throughout the cooling system

Radiator: coolant flows through the coolant, which is composed of metal fins. Air flows through these fins, cooling off the heated fluid

Cooling fan: This moves air across the radiator to cool the coolant fluid

Pressure cap: Usually found on the radiator, this part helps maintain the pressure within the cooling system. It helps to make the fluid more efficient.
