Email Follow us on Facebook @ Car Mechanics Unlucky for some Are you superstitious? I’m not really that troubled by various myths that have floated around for centuries. One that I remember my grandmother (nan) saying in the 1970s – “it’s Friday the 13th this month and I won’t be going out that day.” Weird, I thought, but it did stick in my mind and others reading this may have a similar view on Friday the 13th. The reason I mention this superstition, is because it is considered that Friday 13th of any month is an unlucky day. Up to three occasions of Friday the 13th can occur in a given year – in 2021 there was just one. Well, this superstitious belief wasn’t considered when we were out on Friday August 13th,…

BMW 118i final drive and electrically-controlled differential. Clutch in power flow: • minimal drag losses • highest actuation dynamics • optional control accuracy Overdrive speed difference via internal step gear: • compact design • minimal weight • optimal efficiency • best availability Hydraulic actuation: • optimal control • highest power density Compared to the engine and gearbox, the mechanism that transfers torque to the reardriven wheels is relatively overlooked. Despite the traditional layout of a north-south (longitudinal) engine powering a rear-mounted final drive differential assembly not being as common as it once was, the arrangement refuses to die completely – as many Audis and BMWs testify. Axle layouts Live rear axles are identified by their driveshafts (half shafts) being enclosed within the casting, meaning that the wheels, axle, final drive/differential and axle casing all rise and fall together with suspension movement. While used on many…

Get the 101 on E10 petrol ► E10 begins to replace E5 petrol from 1st September 2021. The new E10 95 RON blend comprises up to 10% ethanol, instead of the previous E5 limit of up to 5%. Whether you drive a new, used, modern classic, historic or vintage vehicle, E10 will affect you. Why is E10 being introduced? The aim is to reduce road transport carbon dioxide levels, especially since new diesel passenger car sales have declined. It also appeases the UK bioethanol industry, which lobbied the government heavily for its introduction. How can I check if my car is compatible with E10? This webpage confirms vehicles that do not contain materials in the fuel system that are affected negatively by petrol containing more than 5% ethanol: If I use E10 in my compatible…

tales from the workshop

FORD FOCUS Poor starting ► This 2009 Ford Focus 1.8 diesel had been starting fine all last winter but now that the mornings were warmer, it needed cranking a lot more than is used to. Although most people realise that the glow plugs are essential in winter warming-up the cylinders to allow the mixture to combust, they are also needed even when the ambient temperature becomes a little higher. Easily accessed on this engine I removed the connecting feed wire to the glow plugs and used the ammeter to check the resistance of each plug. Three out of the four did not pass the test, and as these are more old-school glow plugs and cost less than £9 each I decided that the best option would be to replace all four. The more standard…

project jaguar xf 3.0d belt & pump

There’s not a huge amount of space inside the engine bay of the XF and the 3.0-litre V6 diesel engine that powers our project car looks like it has been squeezed into position under the bonnet. Fortunately, the rear-wheel-drive configuration means the timing belt area of the engine is at the front, so once the induction system has been removed along with several vacuum hoses, wires and mounting bracketry, there’s ample space to remove the timing belt, idler pulleys, tensioner and water pump. We were in for yet more surprises. When we got down to detaching a vacuum pipe from the central shut off valve (CSOV) in the middle of the engine bay, the pipe wasn’t fully fitted. Considering the CSOV is a later type, it has been changed, but whoever…
