Knowing how they work should convince you of its importance. Make sure the fuse for the radiator fan is intact. If it is not, replace it immediately, and this should take care of the . Step by step instruction on how an automotive radiator cooling fan works.
An electric fan motor should freewheel also, if resistance is observed the fan motor has failed and replacement is required.
The idea is to boost the efficiency of your radiator by dispersing the lovely warm air that gets trapped behind it.
You plug the booster in and place it on top of your water-filled radiator.
Rear-wheel drive cars with longitudinal engines usually have engine-driven cooling fans. This clutch is positioned at the hub of the fan , in the airflow coming through the radiator. This special viscous clutch is much like the viscous coupling sometimes found in . This video shows how an normally-open cooling fan switch works.
Scotty Kilmer, mechanic for the last years and counting, shows how to repair the cooling fans in your car.
There are many reasons cooling fans stop workin. Thermostatically controlled motors do not work the fan until the engine coolant rises above normal operating temperature, and then switch off when it has cooled down again. Since radiators are designed to allow coolant to shed heat via the mechanism of convection, a radiator is always more effective when there is air passing through its core. This saves power, since the engine does not have . Are you having the same problems as me?
Trouble shooting an over-heating engine.
The cooling system in your vehicle is of paramount importance to the health of the engine. If the cooling fan motors burn out or fail, the cooling fans will be disabled. The cooling fan motors work together with the cooling fan blades to pull air through the radiator.
If the motor fails the blades will not be able . It spins constantly, never stopping.
Therefore, it draws air, pulling it through the radiator from the outside, during slow and fast speeds. The complaint was overheating due to stopped cooling fan. Shows cross-section diagrams and test equipment in use to troubleshoot failing system.
One of the most common break down issues for older cars and . To begin, you need to unplug them. Today one can find different types of radiator cooling fans on the web so much so that it is difficult to select the best one of the lot. Get an instant estimate for your.
If you notice that the engine is overheating (see the temperature gauge in the dashboard), and you do not hear the fan (s) working get the cooling system inspected immediately. Before the development of viscous-drive and electric fans , engines were fitted with simple fixed fans that drew air through the radiator at all times. At its heart is an efficient fan to gently move the warm air around the room.
With intelligent electronics, the Radiator Booster only circulates the air when the radiator exceeds degrees Celsius, so ensuring no energy is ever wasted.
Rad fans (well electric ones anyhow) are turned on and off by temperature of your coolant not by speed.
