Our carrier DHL is operating near normally across the world with its Air Express service. Allow an extra day for delivery (4 days for Australia and New Zealand), just in case.
  * For the UK only, Royal Mail are delivering the vast majority of orders on time according to our data, but is experiencing higher levels of staff absences, so there may some local delays.
  * We will be working normally and have a large warehouse full of parts that will help keep your car on the road. However, we are seeing some supply delays from factory lockdowns around the world.
Workshop Customers:
  *
Following government guidance, we are open as usual. Taking your vehicle to a garage for repairs is a permitted activity (safety) as long as you observe the social distancing rules. We have strict social distancing processes internally and disinfect daily (not least because we have staff in vulnerable groups). In the circumstances, we have had to close our waiting room. Our mechanics wear gloves at all times and we will disinfect your vehicle with our Zaflora sprays on handing back to you. We would respectfully ask you to show our staff the same courtesy. We also have full amount contactless payment systems.
  * MOTs due for renewal from 30th March to 31st July 2020 were extended for six months. There have been no MOT extensions since then. After the first lock-down, the massive pent-up demand for MOTs overwhelmed supply so even if you don't need to use your car in this current lock-down, it is still strongly recommended to get one done should your vehicle be needed at short notice.

Fit the cam belt tensioner and idler into place and fit the new belt, the new belt needs to be tensioned so the arrow on the tensioner is at maximum, next you need to tighten the camshaft pulleys and remove the cam locking tools. Rotate the engine two hole revolutions to settle the cam belt in.

Next turn the engine another two whole revolutions and refit the timing tools to check the camshaft timing, it the tools do not fit easily redo stage 12 onwards.
