Caterham Vehicle Directory

K-Series Head Gasket Failure (HGF): A common issue on older 1.4, 1.6, and 1.8 Rover-engined models—ensure MLS gasket and PRT are fitted.

Drivetrain "Clonk": A characteristic (often harmless but annoying) slack in the differential and propshaft assembly.

Chassis Corrosion: The thin-wall tubular chassis can rust quickly if the powder coating is compromised—inspect annually.

De Dion Tube Cracking: Structural failure of the rear suspension beam under high stress, particularly on track-driven cars.

Starter Motor Failure: Heat from the exhaust manifold cooks the solenoid, leading to a "click" but no start when hot.

Cooling System Degradation: Small coolant capacity makes the K-Series intolerant of any weakness—hoses perish, fan switches stick.
