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

Symptoms: Loss of coolant, Overheating...

Est. repair cost: £600–£1,200

Cooling System Degradation

Serious

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.

Symptoms: Overheating, Coolant loss...

Est. repair cost: £100–£400

Chassis Corrosion

Serious

The thin-wall tubular steel chassis can rust quickly if the powder coating is compromised. Corrosion typically starts at welds and joints where moisture and road salt become trapped, and can threaten structural integrity.

Symptoms: Rust spots on chassis tubes, Bubbling paint or coating...

Est. repair cost: £800–£3,000

Starter Motor "Click"

Minor

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

Est. repair cost: £150–£300

  • Look for a "remote thermostat" or PRT kit to prevent thermal shock to the engine.
