We have written a short article on the importance of fuel cooling and the infamous V12 hot start problem here

Over the years, Jaguar has maintained its position as a leader in suspension sophistication and the launch of the E-type in 1961 was where it all began.

At the time, most production cars were still using live axles. This, of course, impacted ride quality and made cornering a fickle affair. Designed by Bob Knight, Jaguar’s first generation of independent rear suspension (IRS) took five years to develop and was a game changer in ride comfort.

While its first production application was in the E-Type, the Jaguar IRS assembly was refined and used continuously until production of the XJS ended in 1996. Even then it carried on in modified form into the XK8, XJ300 and XJ308. The smooth ride and excellent roadholding offered by Jaguar’s IRS assembly played a significant role in making the XJs the highly-desirable classics that they are today.

But even the best designs need a little helping hand. Unless professionally restored within

As one of the UK’s leading restorers of luxury classic cars, we come across all sorts of common problems that require the attention of our specialist engineers.

At KWE our aim has always been to ensure our customers receive a ‘better than new’ restoration service for their Jaguar XJS, XJ, XK and Aston Martin DB7 vehicles. So, we believe it’s important to share information that will ensure these vehicles maintain their reliability and roadworthiness.

We’ve noticed an increase in the number of classic cars being delivered to us for restoration with fuel system failures. Here we offer 7 preventative tips that will keep your vehicle in good condition and help avoid expensive remedial repairs.

Rust and sludge

The primary problem is due to the accumulation of rust and sludge in the fuel tank.

Even though high quality fuel filters are used in the fuel system, fuel pump damage and clogging of the injectors can occur.

While external crash damage to a vehicle is clearly noticeable, other parts are less so and therefore require thorough checks and repairs before a car is deemed roadworthy and safe to drive.

A car’s powertrain comprises several important components that are prone to serious damage if a vehicle is unfortunate enough to be involved in an accident.

In most modern vehicles the powertrain includes the engine, transmission, drive shaft, differential and the final drive. Together, these components transmit the engine’s power through to the road surface.

Our workshop technicians have been kept particularly busy recently with two Jaguars XJSs that were both involved in [...]

KWE has developed a way of repairing the Delanaire Mark 2 aircon servo amplifier. Spares are unobtainable and the amplifier has a limited life. The symptoms of failure of this device are a lack of temperature and air direction control, even though the heating and cooling systems are working.

Similarly, KWE can now replace or repair the Delanaire Mark 3 frost thermostat,
