A damaged or dysfunctional radiator causes the cooling system of a vehicle to work overtime to keep its temperatures at a manageable degree. Most radiator problems are first noticed when the temperature gauge reads levels above normal.
Working Principles of Radiators
Radiators are designed to dissipate heat generated in your vehicle to the environment. With the help of interconnected tubes and a liquid coolant which flows through these tubes, heat is sufficiently lost to the environment.
Radiators have an inlet and an outlet. The inlet receives the coolant which has absorbed the generated heat in the engine. The coolant flows through a parallel arrangement of tubes in the radiator. Heat from the coolant is conducted to the fins (flattened aluminum sheets in the radiator) which in turn dissipate the heat through the flow of air current generated by the fan positioned just behind the radiator.
The numerous parallel arrangement of tubes in the radiator along with turbulators ensures that sufficient amount of heat is lost from the coolant before it flows out of the radiator via the outlet.
A turbulator is a type of film sometimes inserted into the tubes the coolant flows through in a radiator. The sole purpose of the turbulator is to regulate the degree of turbulence in the tubes; if there is little or no turbulence, the coolant is more in contact with the tubes, thereby losing more heat from the radiator. But if the degree of turbulence is high, then the coolant doesn’t come in contact with the tube or you could also say, the coolant doesn’t spend much time in contact with the tubes so little heat is lost from the radiator.
There are also radiator-like device called a transmission coolers in tanks positioned on either side of a radiator. Unlike a radiator, heat is exchanged between oil and the coolant in the radiator.
When Is It Time To Take Your Car for Radiator Repair Services?
With continuous usage, the tubes in the radiator can be clogged up with deposits of mineral. This causes the coolant not to flow as easily and effectively as before. When this occurs, there is a reduction in the amount of heat lost. If this is not remedied in time, heat generated while your vehicle is in use will accumulate to a degree that becomes unstable for your vehicle, that is if the pressure that builds up in your radiator doesn’t damage the thermostat, pumps, and hoses first.
Radiators Diagnostic and Repair Procedures
It is common practice for people to manage this kind of problem, but it is wise to take your vehicle to a radiator repair shop to have it looked over. Radiator leaking is the evil and it’s the main reason to stop your car anywhere in the road. If you care about your car and not getting stranded in the middle of nowhere.
Radiator repair technicians usually start by inspecting the radiator for cold spots. They also run temperature and pressure tests to clarify that the cooling system is functioning properly.
If these tests return negative results, the technicians will have to specifically determine where the trauma regions in the radiator are. In an event of a blockage, the technician may have to carry out a process called a Full Coolant Flush in an obvious attempt to flush out whatever deposits are responsible for the blockage. If any part of the radiator requires replacement, the technician will suggest them to you.
At the end of this procedure, your vehicle will be test driven. This is to make certain that your car maintains its normal temperature and pressure levels.
If the problem or overheating persists additional tests on the coolant system will be performed to discover where the problem lies. When the problem has been identified, your vehicle will be inspected and repaired. In the end, your radiator and cooling system will be functioning at optimal levels.
