The quality of domestic gasoline significantly reduces the service life of spark plugs at Skoda. There are situations when replacing spark plugs is simply necessary to start the engine. Therefore, it is important to be able to change the candles yourself and do it carefully.
Necessary
- Candle head 16 with a rubber washer for fixing and holding the candle inside the head and an extension at least 150 mm long with a knob.
- 5 mm hexagon.
- Screwdrivers.
- New candles.
Instructions
Step 1
Remove the plastic engine cover. To do this, find the 4 screws for its fastening with rubber plugs. Use a Phillips screwdriver to turn these screws 90 degrees to either side. Lift the cover strictly vertically so that the plugs do not pop out and are not lost. Locate the four massive plastic ignition coil housings. Each body is secured with two hex bolts and a wiring harness fits each.
Step 2
Using a flat screwdriver, lift up the metal clips of the wire connectors located on the plastic housing of each of the ignition coils up to the stop. Disconnect the connectors. Unscrew the fastening bolts of the ignition coils to the block head with a hexagon. Remove the coils by gently pulling upwards. Access to wells with spark plugs inside will open. The long part of the ignition coil housing acts as a high voltage wire and has a rubber tip.
Step 3
Blow out the spark plug wells with compressed air to avoid contamination of the cylinders. Unscrew the candles with a special head with a nozzle. The design of the spark plug head prevents the plug from falling out of the head when removed. With the same tool, install a new candle in the well. To do this, insert the candle into the head and slightly press on the threaded part of the candle so that it sinks into the rubber washer. The washer will secure the spark plug and prevent it from falling out.
Step 4
Use your hands to start screwing in the plug by rotating the head through the extension. The candle should be screwed in easily and effortlessly. If this is not the case, stop screwing in order not to damage the threads of the block head (repair is very expensive). After screwing in by hand, finally tighten with a screwdriver. Find out the tightening method and torque from the labels on the spark plug packaging.
Step 5
Install all removed parts in reverse order. When installing the ignition coils, make sure they fit snugly against the spark plugs.
