See also heater upgrade part 1, part 2, part 3, and the 3D printed valve mount. The OEM water valve is another vulnerable point in the problematical Jaguar heater system. The Four Seasons 74000 replacement valve should make a significant difference in the flow of heated coolant (but it works......
See also heater upgrade part 1, part 2, and the 3D printed valve mount. The heater upgrade includes a more powerful motor with a choke, a new squirrel cage fan, and an electronic control module to control motor speeds and performance. The fan motor replaces the prior unit, but the......
See also disassembly of front seats. The front seats operate on glides that fasten to two runner mounts that extend towards the rear seat. Originally, these runner assemblies had some sort of smelly jute-like tonque-shaped padding, and we decided to use an odor-free felt replacement. The exact purpose is obscure,......
Back in the pre-digital manufacturing age, before robotics and computer numerical control (CNC), cars were largely hand-assembled. Tolerances might be 1/8-inch or so on the chassis, and thus trim pieces did not necessarily align exactly over pre-drilled holes. Enter the lowly spire fastener (also called speed fasteners). Spires can easily......
As part of the heater modification, the Jaguar OEM valve will be replaced with a new Four Seasons 74000, a readily available black plastic unit. The new valve requires a different mount, and this presented an opportunity to design something using OnShape and then physically manufacture it using 3D printing......
See also windscreen washer disassembly blog. While the Lucas Screenjet appeared in fine condition when it was removed from the car, a closer inspection revealed corrosion inside the pump that couldn’t be easily repaired. Fortunately, the motor top and pump are still manufactured in the U.K. and a new one......
See engine block cradle design. After many moons hanging off the engine stand, the 2.4 engine block and related parts now rest, perhaps more comfortably, on a specially made cradle that sits on the floor. The height of the cradle performs two functions: 1) it prevents the engine weight from......
The bonnet release cable is fixed on the passenger side dash in a small slot below the cubby box. The release cable then passes through the firewall in the 3rd from the top of four holes (the bottom hole is plugged), traces the top of the engine bay, and finally......
During test drives prior to disassembly, a bump in the road would sometimes result in a rattle coming from the boot, and the prime suspect was the wheel jack mounted against the forward wall (that is, immediately behind the rear seats). It is doubtful that this jack would actually ever......
See prior discussion about radio alternatives as well as details on how to fit a modern DIN unit into the Jaguar radio panel: parts 1, 2, and 3. Update April 29, 2015 The DIN standard defines the dash panel opening, height and width, but does not specify the depth of......
