See also engine front mount post. Aftermarket parts sometimes depart from the original manufacturer’s specification, as we’ve noted several times. Based on comparisons by Lin Rose, a second look at the front engine mount pads was warranted; two quality levels are offered by SNG Barrett, but we had already installed......
About a year ago, the air cleaner was removed, and today a repainted cleaner had its test fitting on the restored engine block. The colors have been slightly modified. The oil container rim, originally black, was treated with high temperature aluminum POR paint. The three side clips, also originally black,......
See also prior discussion of clutch, flywheel, and starter motor upgrades. The primary impact of an aluminum flywheel is weight … a 50% reduction! So what does a 14 pound weight saving achieve? Flywheel physics is quite complicated. On one hand, the flywheel stores rotational energy which can be converted......
Back in December 2014 we assessed the gearbox-overdrive unit, and now it’s time to do the restoration work. The gears worked fine prior to disassembly in June 2014, so the internal mechanisms will be left untouched. There was so much grime that the integrity of the seals couldn’t be determined......
The Mk2 antenna, located just outside the A-post (door/window pillar), came in a variety of configurations since many were installed aftermarket by Jaguar dealers. In our case, the surviving radio turned out to be a 1970s Sanyo replacement for the original Radiomobile radio while the antenna, a simple manual extended......

After installing the heater casing, the next step was wiring up the motor and electronic control module. The electronic control box, potentially sensitive to heat, was tucked away under the passenger dash. A Molex connector joined the harness to the fan motor, which passes through the dip switch firewall hole,......
See also heater upgrade part 1, part 2, part 3, part 4 and the valve mount. The last construction task involving the heater casing itself is setting the proper flap angle and rotation. The green flap above is the hot-cold control; if vertical, the flap forces air through the heater......
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......
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......
