Radiator, Water Pump & Cooling Systems
Your radiator & cooling system require regular servicing. Exchange Radiators and Water Pumps, coolant change, thermostat test, radiator hose inspection
The most common cooling system problems:
- Obstructions or other gunk in cooling system
- Overheating at idle
- Radiator coolant overdue for change
- Weather extremes
Australian drivers are aware of the temperature extremes one can experience in the city but away from the coastal strip there is some serious heat your car’s engine needs to shed via its cooling system.

Why your radiator & cooling system require regular servicing.
To keep the engine at a safe temperature, coolant is pumped through the engine's cooling passages, collecting heat as it goes. The coolant then leaves the engine via the radiator hose and travels to the radiator where it passes through a series of finned tubes.
The purpose of fins is to increase the surface area of the tube to allow the heat to radiate away in the air flow, hence the name. The cooled coolant is then returned to the engine via another hose to repeat the cycle.
Engine coolant has a limited life and should be completely drained (including the engine block) flushed and refilled with the correct coolant for the particular vehicle and the way it’s being operated. Change coolant no later than 24 months.
What To Do If Your Car Overheats.
Never remove the radiator cap when the engine is hot – it’s very dangerous. A severely overheated engine can take several hours to cool. If the coolant has leaked out, the engine could be much hotter than is indicated by the gauge.
Always find and fix the cause and any damage sustained. Simply adding water to an overheated engine will rarely fix the problem.
Never use cold water to refill a hot engine – it can cause further damage.
Engine damage may not become apparent for days, weeks, or even months after the overheat.
During an overheat, scale from inside the engine will often become dislodged and block the radiator causing further problems.
Thermostats should be checked or preferably replaced after an overheat. They must not be removed to overcome overheating problems. Fitting a lower temperature thermostat to reduce overheating only masks the real problem, and causes others.
In the case of a severe overheat, the extent of damage and the cost of repairs won’t be known until the engine is dismantled and inspected.
Your cooling system is extremely important for your car as it removes operational heat from the engine so it does not reach overheat. Regular servicing of your car’s cooling system is vital to maintain reliable performance and to avoid very costly engine repairs.

Car Cooling Sub-systems:
How does your car's cooling system work?
Some engine energy generated by your car as a result of burning fuel is converted to mechanical energy to drive your car; the balance converts to heat. Some of that heat is blown out of the exhaust pipe, but the rest heats the engine itself. Your car’s cooling system works by moving coolant through the engine, where it picks up heat, and then passing that heated coolant through the radiator, where the heat is then transferred off to the air which is passing through the car’s radiator.
The cooling system must have enough reserve cooling capacity to cool a car under extreme operating conditions such as when towing a caravan or operating in scorching heat, as well as maintaining the correct engine operating temperature in extreme cold, such as on a visit to the snowfields or during cold weather events.
The warning signs of an unwell cooling system
- Temperature gauge or warning light out of range.
- Puddles of greenish to brown liquid on the garage floor.
- Engine making a pinging sound on acceleration.
- Any sign of steam from under the bonnet you should shut down the engine.
Automotive Cooling System Components.
A car's radiator has the important task of keeping the engine cool. Radiator repair and maintenance is essential to the health of your engine and your vehicle. The most common radiator repairs involve simple part replacement and radiator fluid exchange. Additionally, most vehicle manufacturers recommend replacing coolant solution at regular intervals.

Automotive Radiator & Cooling Repair Service Rockhampton.
When you drive, the parts within your engine are creating some serious friction – and that friction generates heat. Engines run efficiently when warmed up, and the temperature is maintained by many engine cooling parts; the radiator, cooling fans, water pump, thermostat, coolant, pressure cap, overflow tank reservoir and other misc. parts.
In order to stabilize the engine heat, the water pump sends coolant into the engine block to absorb the engine heat. The engine heat is then run past a thermostat, which maintains the engine coolant temperature. The coolant is then sent to the radiator to release the engine heat. Radiator cooling fans keep the radiator cool with airflow. The coolant is then sent back to the engine block to repeat the cooling cycle. The cooling system and radiator work together to keep the engine at a safe temperature.
