Question 1

What is Head Gasket Failure (HGF) on the Caterham Caterham Seven (Rover K-Series)?

Accepted Answer

The Rover K-Series engine is prone to head gasket failure due to its small coolant capacity and "sandwich" construction.

Question 2

What is Starter Motor "Click" on the Caterham Caterham Seven (Rover K-Series)?

Accepted Answer

Heat from the exhaust manifold often cooks the starter motor solenoid, leading to a "click" but no start when hot.

Question 3

What is Cooling System Degradation on the Caterham Caterham Seven (Rover K-Series)?

Accepted Answer

The K-Series has a very small coolant capacity, making it intolerant of any cooling system weakness. Coolant pipes perish during winter storage, header tank caps fail and fan switches can stick, all leading to rapid overheating.

Question 4

What is Chassis Corrosion on the Caterham Caterham Seven (Rover K-Series)?
