Displacement Mark Vii:
3.4 Liters (3442 cc)
Displacement Xk Series:
Initially 3.4 Liters (3442 cc), later 3.8 Liters (3781 cc) for XK150 and some later Mark VII/VIII/IX models.
Horsepower 3.4L:
Approximately 160-190 bhp (depending on tuning and carburetor configuration)
Torque 3.4L:
Approximately 190-210 lb-ft (depending on tuning)
Carburetion Mark Vii:
Typically twin SU carburetors (e.g., H6)
Fuel Type:
Premium Unleaded Gasoline (historically Leaded Premium)
Timing Mechanism:
Timing Chain (The manual lists 'Timing Belt Service Procedures', which is likely an error or refers to a common misconception/aftermarket modification, as these engines use chains. The manual would detail chain maintenance.)
Crash Testing:
No formal crash ratings exist for this era of vehicle as per modern standards.
Braking System Type:
Hydraulic drum brakes on all four wheels, with later models potentially having front discs as an option or standard.
Seat Belts:
Typically not standard, often an aftermarket addition for later use.
Chassis Construction:
Body-on-frame construction, with a steel monocoque chassis for some XK models, but Mark VII is body-on-frame.
Oil Change:
Typically every 3,000 miles or 6 months, with specific guidance in the manual.
Grease Points:
Regular chassis lubrication required at multiple points (e.g., suspension, steering linkage) every 1,000-2,000 miles.
Engine Oil:
SAE 20W-50 or SAE 30 (depending on climate and availability, check manual for specific recommendations; historically multi-viscosity oils were emerging).
Coolant:
Ethylene Glycol based antifreeze with water, typically a 50/50 mix. Manual will specify type and capacity.
Brake Fluid:
DOT 3 or DOT 4 (check manual for exact specification; historically DOT 3 was common).
Transmission Fluid Manual:
Gear oil (e.g., GL-4 80W-90 or GL-5 80W-90, specific viscosity may vary; consult manual).
Transmission Fluid Automatic:
Dexron-II or equivalent (for Borg-Warner BW-8)
Engine:
Core plug corrosion, oil leaks (e.g., rear crankshaft seal), carburation tuning difficulties, potential for head gasket failure if overheated.
Suspension:
Wear in kingpins and bushings, loose steering box.
Electrical:
Aging wiring insulation, Lucas electrical components (often perceived as less reliable), generator charging issues.
Bodywork:
Rust susceptibility, particularly in sills, wheel arches, and floor pans.
