How Can Ford Glow Plugs Work

How Complete Ford Glow Plugs Donkeywork?


Glow Plugs


Glow plugs are electrical heating devices in Everyone cylinder of a diesel engine that advice in ignition. Glow plugs are mythical of metal and are tipped with a heating filament fictional of either iridium or platinum. These materials are resistant to Exorbitant heat and rust. When cold-starting a Ford diesel engine, electrical now passes over the filament to dream up a flash fevered stop. This heat directs into the cylinders of the engine block, thus raising the temperature in the combustion Hospital ward To admit for fuel ignition.


Operation


Glow plugs are controlled by a timer in that they charge to be active for between five and 20 seconds to accomplish ignition. When the engine block reaches the temperature designated for ignition, the glow plug relay shuts off the "Wait to begin" flare. Turn the principal to the "Initiate" position and the Motor lorry is ready to function. They should each measure around 12 volts. Check the remaining glow plugs within the edge of each valve cover. There are nine wires, each connecting to the glow plugs and fuel injectors. Remove the wire connector by pressing the latch and prying the connector apart with a flathead screwdriver.



If the truck is equipped with two relays, then the glow plug relay is the one with the brown and yellow wires leading toward and away from it. Check the voltage for at least 10 seconds. Place the ground probe on a bare part of the engine block and a source probe on each terminal. In some newer cars, the glow plugs can go on to function for up to three minutes after ignition to sincere emissions, by reason of a arctic engine can hog an adverse development on combustion performance.

Maintenance

Examination the glow plug relay by measuring the voltage at Everyone of the sizeable terminal posts after starting the Motor lorry. The relay is on top of the engine behind the fuel filter housing. The four wires for the glow plugs are the two farthest to the front and the two farthest to the back. Use a wire tester to check resistance across each of the wires, keeping the ground probe attached to a separate piece of metal on the engine block or to the negative battery terminal. Each glow plug connection should measure between 0.6 and 2 ohms.
