OTC 3673 Diesel Glow Plug Tester

Product Information

Your glow plugs work hard under extreme temperatures to start your engine, regardless of the weather, that’s why your car deserves the best. 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. There is usually a cover or cap over the glow plugs. Removing this will allow you to apply the multimeter clamps to the glow plugs. Look at the connector and pins for any signs of rust, corrosion or looseness. Take this opportunity to clean them. This alone could have a beneficial effect.

While you can still drive with one broken glow plug, you’ll find it extremely difficult to start your car as soon as two or more glow plugs malfunction even if the weather is warm. It’s important to note that a problem starting your car can also be a symptom of a problem in the fuel system or battery. We would, of course, be remiss if we didn’t mention Ab Tools-Us Pro Glow Plug Tester for daily purpose. The ab tools-us pro glow plug tester is high quality, accurate gauge. Also, this can be used on modern high compression diesel engines. Glow plug applications include: NGK CZ303, Y8002AS and YE13; Mercedes Benz OEM 001 159 5701 and 001 159 6601. Remember that these are a vital part of the glow plug ignition system. Hence, relays must be fully functioning, particularly during cold weather. How Does It Work? At its peak, the glow plug’s temperature could reach approximately 1,000 degrees Celsius. That guarantees the diesel or air mixture will explode even at low temperatures.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.

Do you have a diesel car? Then you might be familiar with glow plugs, which are used to create ignition in diesel vehicles. They are the equivalent of spark plugs in a petrol car but work slightly differently to start the engine. 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. Engine cranking: the glow plugs are deactivated to ensure maximum battery capacity is available for the starter motor. At cold temperatures, the diesel or air mixture won’t ignite right away. What does the glow plug do to protect combustion when the engine is cold? It increases the temperature within the cylinder’s combustion chamber before the engine starts.Subtract the resistance value of your multimeter from the resistance value of your glow plug. For example, if your plug's resistance measured .9 ohms and your meter's resistance measured .2 ohms, the real reading for the plug is .7 ohms. A glow plug is a heating element that heats incoming fuel and air to encourage efficient fuel combustion in a diesel engine. The fuel combustion starts your engine so that you can drive. Each cylinder of your engine has one glow plug, either in the pre-chamber (pre-chambered engines) or in the combustion chamber (direct-injection engines). Caution: Some glow plug manufacturers (including NGK ) recommend against applying battery power to the glow plug. This is because the plug can overheat and sometimes melt. Always follow directions from the glow plug manufacturer and tester manufacturer. Not all testers are compatible with all plugs. Using a glow plug tester:

In essence, a multimeter is a box of electronic circuitry that can be used to run a variety of tests on electrical wiring or devices (hence its name ‘multimeter’: multiple measurements). You may be extremely familiar with your model of multimeter already – but if not, here is a refresher: Glow plug testers sound like a good idea, but are usually very time consuming to use, and not very useful (because they only let you detect problems in the glow plug). Most glow plug testers are basically just an ammeter attached to four wires, and a switch. This is very difficult to diagnose but can be a problem as well. Are your fuel injectors squirting a big stream of raw fuel? That could stress the glow plugs’ tips. Visualize if you heated up the glow plugs red hot and then continuously plunged them in cold water. Einsatzmöglichkeiten bei Glühkerzen u. a.: NGK CZ303, Y8002AS, YE13, Mercedes-Benz OEM 001 159 5701, 001 159 6601 Applications include: Chrysler 3.0L CRD and Jeep 3.0L CRD; Mercedes Benz A Class, B Class, C Class, CLA, CLK, CLS, E Class, GL/M/S Class and Sprinter 2.1 CDI; Smart Forfour and Mitsubishi Colt.Put the clamp around the glow plug power wire, or around the top of the glow plug. Make sure that the clamp closes completely, and that the clamp meter is safe from damage.

Disconnect the power cable from the glow plug. If you don’t do this, you will be measuring the resistance of all the glow plugs at once, instead of just the one you want to test.

Auto Air Conditioning We have access to one of the largest ranges of air conditioning parts in Australia White smoke: smoke is common when there is not enough heat to burn the fuel. This can happen on colder mornings before the car has fully warmed up, but faulty glow plugs can also cause smoke on startup. The glow plug relay then converts the current for the glow plugs on and off accordingly, which causes them to heat up immediately and ignite the fuel in the engine. Einsatzmöglichkeiten u. a.: Chrysler 3,0 CRD, Jeep 3,0 CRD, Mercedes-Benz A-Klasse, B-Klasse, C-Klasse, CLA, CLK, CLS, E-Klasse, GL-/M-/S-Klasse, Sprinter 2,1 CDI, Smart Forfour, Mitsubishi Colt. Rough idling: when the combustion chamber can’t reach the right temperature, it may also result in rough idling once the car has started.
