Faults of radiator
pollution or damage to the core;
damage to the tubes;
clogging of the radiator outer surface;
depressurization.
Symptoms of radiator faults
car engine overheating;
external antifreeze leak;
increased consumption of coolant;
deterioration of coolant circulation.
Causes of radiator faults
end of life;
wear;
impact of pressure;
untimely coolant replacement;
expansion tanks leakage;
deposits on the inner side of the radiator;
impact of high temperature;
mechanical damage;
metal corrosion;
untimely service;
poor quality of the coolant.
Diagnostics
Diagnosis of the radiator should be carried out every 6 months. If you have problems with the engine cooling you should implement emergency diagnosis. You should begin with the radiator inspection for the presence of coolant drips. If there are any, it says that there are cracks in the radiator. Warm up the engine, check the pipe, wearing gloves. If the tube bursts, the fault is probably in a valve or a rubber gasket. Also make sure that the coolant level is not below the minimum mark on the tank.
Radiator Repair
Initially, you need to clean the radiator. Cleaning should be carried out every 2 years, changing the radiator cap. Clogged cells can be cleaned by blowing compressed air or washing with water under pressure. You can get rid of the deposits inside the radiator with water. you should rinse in a direction opposite to the coolant circulation.
or repair, you can use a special liquid that closes the cracks. This method is effective with the appearance of microcracks.
In case of the housing deformation it is necessary to flatten the radiator, to eliminate the holes with the help of gas-welding machine.
Replacing the radiator
You should replace the item in the following cases:
broken radiator cells;
leakage;
leak in a few places;
blockage of the core tubes.
Replacement should be made exclusively when the radiator is cold. Drain all coolant and dispose of it. Open the attachment and fasteners, and then disconnect the hoses. Remove the old radiator, and install a new one in its place. Then snap fastenings and clamps, attach hoses. Fill in cooling liquid.
What are the functions of a radiator and how does it work?
The functions of a radiator depend on the system it belongs to. For example, there are components for cooling the engine or the oil in the engine lubrication system, the fluid in the hydraulic power steering, the transmission, or the differential. There are also parts used in the interior heating systems. Most modern radiators are made from aluminium because of its abundance as a natural resource. Coolant or oil are used as the working fluid. Structurally, radiators are tubes connected by plate fins or corrugated fins, which make them more efficient at cooling. Cold air is often supplied by electric fans and also comes from air intakes built into the car body. Oil radiators have special turbulators for improving the air flow. A radiator grille usually protects the radiator and prevents stones and other objects from getting in.
Why is the lower radiator hose sometimes cold?
If the outside temperature is low and the engine hasn’t reached its operating temperature yet, coolant flows in a small circle. In this case the lower pipe will be cold. If this isn’t the case, it is a sign of:
thermostat failure;
a broken water pump;
airlocks or excessive dirt in the system.
Get your car serviced at a garage to determine the precise cause.
What causes airlocks in the engine cooling system?
a loose fitting expansion tank cap;
a fault with the radiator cap valve;
leaks in the inlet pipes and hoses.
Airlocks also occur if you do not bleed the radiator correctly after replacing the coolant. They can also be a result of the leaky cylinder head or its worn gasket, which both lead to exhaust gases getting into the system.
