OTC 3673 Diesel Glow Plug Tester

Product Information

Connect the two leads of the multimeter together, making sure the metal clamps/pins on the leads touch each other, and record the result. If you are using a digital multimeter, the precise reading will appear across the screen. At this point you may be able to use your multimeter’s calibration function to adjust the reading to zero. Located on the engine and with a direct connection to the engine control unit, the control module uses a microprocessor to analyse input from the engine control unit to determine information related to the working of the glow plugs. This includes when to switch the current for the glow plugs on and off, and how much current is required as this will differ depending on the starting temperature of the engine. The current to the glow plugs is turned on during the pre-heating to warm up the engine, stand-by time when the engine should be started, and post-heating to meet increasingly strict exhaust gas standards and optimisation of combustion processes.

To test your glow plugs, simply connect a 12-volt test light to the positive battery terminal. Then disconnect the wires from each of your glow plugs and touch the probe of the test light to the terminal of the glow plug itself (not the wiring harness). If the light doesn’t light up, the glow plug is bad and should be replaced.Poor engine power – after a difficult start, bad glow plugs will make it difficult for your car to run properly, due to improper combustion which reduces power and efficiency. Analog meters may apply higher voltage to the circuit than the digital meter, so use them with care. [2] X Research source Post heat: the glow plug temperature is regulated via PWM whilst the engine is running. This helps to reduce engine cold running noise and emissions. The post heat run time can vary greatly as it depends on a variety of environmental factors, the engine conditions, and the system design. Disconnect the plastic beauty cover from the engine’s top. Pull it upwards to free the rubber cups from the mountings. Disconnect if there are any other rubber cups on the engine and reinstall them in the plastic cover hooks. Flame Start System (Type GF) delivers reliable, convenient and green cold-starting performance even at low temperatures. Available in two versions (12V and 24V), the Flame Start System has a short pre-heating time and a long post-flame time.

Glow plugs ensure your diesel car starts – no matter how cold it is. Located in every cylinder of your engine, they ensure your car burns fuel efficiently, with minimal polluting gases. But, what can you do if you start to suspect that your glow plugs aren’t working as well as they should be? How can you tell if your glow plugs need to be tested?

Injected diesel fuel ignites if the cylinder charge temperature reaches 850° C during compression. However, this temperature may not be achieved with cold ambient air conditions and engine components. In these circumstances, the glow plugs are activated to heat the cylinder charge and ensure adequate combustion. Refer to your shop manual to determine the acceptable resistance range for glow plugs in this vehicle – usually it will be no more than 6 Ohms.

Rapid glow plugs have two coils internally connected in series, a small heating coil at the plug tip and a larger regulating coil within the plug case. These systems use Pulse Width Modulation (PWM) of the supply voltage to regulate the circuit current and to control glow plug temperature. Compared with other glow plug tester in this category, the Draper Glow Plug Tester has a design with broader appeal. To bring you the tool you need, the draper buying team sources innovative products, which adhere to strict ethical and quality standards, from all around the world. When it comes to finding a reliable glow plug tester, the draper glow plug tester is definitely your best option. The location of the glow plugs in the engine will vary based on the make and model of the respective vehicle. Consult the manufacturer’s handbook for the vehicle to find the correct location. If the area around the glow plugs has dirt or build-up, clean it first. Some manufacturers offer special tools (“reamers”) to clean out the bore where the glow plugs are inserted into the cylinder head. These tools clean out carbon build-up inside the combustion chamber or pre-charge chamber, as well as the threads that the glow plug screws into. Glow plugs for auxiliary heaters (Type GH) for additional warmth and comfort even when it’s icy cold outside. Different versions meet the needs of auxiliary heaters in both petrol and diesel vehicles.If one or more of your glow plugs is defective, it will allow diesel to leak into the exhaust pipe. As the exhaust heats up, the leaked fuel will burn and produce white exhaust smoke. This will only last for a few minutes after you start the engine. Depending on the system type and engine operating conditions, the glow plugs may be activated for a period of time after the engine has started. For the best quality fitment, talk to one of our specialists at Natrad. Our range is suited to a huge variety of vehicles. Step-by-step guide Add to this the fact that it also measures resistance for evaluation of the specifics of that plug and it’s easy to see why every mechanic needs one in their tool kit.
