MD2010-2040 and 2000 series

For owners of the compact range of diesel engines a reminder that if your engine tends to overheat when under load, now is the best time to check the exhaust elbow (bend) for a build up of carbon. When checking for this don't be fooled by the fact you can see right through or can blow through with little effort. A small reduction in flow rate is sufficient to cause overheat condition in the most undesirable of situations. Best way to deal with the problem is to remove the elbow, suspend securely on a suitably bent wire coat hanger. Mix carefully a solution of caustic soda and having kitted yourself with suitable gloves and goggles lower the elbow into the solution for the recommended time and do remember to rinse well after this de-coke. A word of caution safety first must take priority over all other considerations. Final word of caution do not attempt to remove deposits with screwdrivers welding rods and the like as exhaust elbows are a couple of hundred quid and sharp tools tend to punch through the twin wall internal, so making them into scrap.
