Spark plug difficult access
This 2008 Volkswagen Touran had been to one garage, which had refused to change the spark plugs, before being brought to us. We discovered why when attempting to remove plug number three – it was extremely tight and we were concerned that the plug had been cross-threaded. With this in mind, we agreed to carry out the work, but told the owner that if the plug had been cross-threaded, the job would not be quick or cheap because the inlet manifold would need to be removed to give access for a replacement thread insert.
As things worked out, using a bar on the stubborn spark plug was sufficient to remove it, and the customer was happy to hear that there had been no damage to the thread. The spark plugs on this engine aren’t easy to access and it’s important to always wind them in fully by hand to prevent the possibility of cross-threading.
Access to the spark plugs through the inlet manifold is tight and care must be taken to ensure they are correctly threaded.
