Spark Plug Wrenches are hand tools of box type which allow to easily perform replacement of hard-to-reach ignition system elements. Fixation of the spark plug is provided due to the hollow working head with inner facets, and screwing in and out – by rotating the handle. The tools are generally made of hardened steel due to which they effectively cope with high loads and serve long.
Types of Spark Plug Wrenches
- Single-unit. They are reliable and wear-resistant. They are a solid tube, at the end of which the faceted working element is located. They can be:
- Straight. The handle is a continuation of the functional part. Usually they are sold at low prices.
- T-shaped. The handle is located perpendicular to the tube with facets. They are more convenient in work.
- Hinged. Due to the moveable head they are indispensable in conditions of limited access to the components.
- Magnetic. They draw and hold the spark plug which minimizes the risk of its falling.
The tools also differ by the dimensions: the head diameter and length. The first parameter for the most products presented in catalogues is 14, 16 or 21 mm. The second index is usually 60 – 560 mm. Long tools allow to work even with deeply located parts. Moreover, you can order online sets of spanners with different characteristics.
Tips on Spark Plug Wrenches use
- Use the tool only for its purpose and follow the manufacturer’s instructions. Don’t make much effort when mounting the spark plug: otherwise, you can not only break it but also get the engine out of order.
- Before components removal, blow out the spark plug well with pressed air from the compressor. It will allow to avoid getting of dirt into cylinders during works performing.
- When mounting new components, apply chemical agent preventing corrosion to the thread. It will make their removal after working lifespan end easier.
