Cooling System
Common to all vehicles
Updated to a reinforced cooling-system specification using carefully selected, high-quality Japanese-made parts
Cooling-system parts are easily affected by heat and age-related deterioration. If they deteriorate, they can cause coolant leaks, rising water temperature, and overheating. By replacing and adjusting each component, we restore proper coolant circulation and temperature control.
The Rover Mini was born in the UK, and in Japan’s hot and humid climate the cooling system is placed under greater strain, making the car prone to overheating. For this reason, Classca improves performance using carefully selected Japanese-made parts. We replace consumable components such as a 3-core radiator and newly developed or upgraded hoses.
In addition, the genuine thermo switch for the electric fan can have inconsistent operation, so we replace it with a Japanese-made sensor. This enables stable control, operating at around 92°C and stopping at 95°C, keeping coolant temperature consistent and helping maintain stable driving even in summer.
Furthermore, the genuine cooling fan blade is thin and prone to deformation from heat, so we replace it with a reinforced, thicker type to improve the stability of cooling efficiency.

Suspension
When suspension components deteriorate, driving stability can decrease, and noise or vibration can increase. We inspect joints, bearings, and suspension parts, then replace worn components to restore proper suspension movement.
For this vehicle, we will install and replace a Hi-Lo kit for rubber-cone suspension. This adds ride-height adjustment functionality to a rubber-cone vehicle, allowing fine ride-height adjustment. After installation, the height will be adjusted to the appropriate level.
Parts scheduled for replacement
Parts carefully selected by Classca
- Lower arm bushes
- Tension rod bushes
- Rack boots
- Rack bush
- Radius arm overhaul
- Hi-Lo kit for rubber-cone suspension
- Upper arm oil seal
Drivetrain and Undercarriage
Deterioration of drivetrain components, mounts, and seals can cause vibration, abnormal noise, and oil leaks. This maintenance replaces worn parts to restore proper power transmission and undercarriage movement.
Parts scheduled for replacement
Parts carefully selected by Classca
- Outer CV joint boots
- Inner CV joint boots
- Diff side oil seal
- Striking oil seal
Exhaust System
Exhaust-system parts are easily affected by heat, vibration, and age-related deterioration. If they deteriorate, they can lead to exhaust leaks, abnormal noise, and reduced exhaust efficiency. We check the condition of the muffler, pipes, gaskets, and support components, then replace worn parts to restore proper exhaust flow and sealing.
For this vehicle, we will replace the catalytic converter. As internal deterioration can reduce exhaust purification performance, we replace it with a new unit to restore proper exhaust processing.
Parts scheduled for replacement
- Exhaust down band
- Catalytic converter gasket
- Catalytic converter
- Diff side stay
Engine Area
Parts deterioration can cause oil leaks and engine issues. This maintenance replaces and adjusts worn components to restore proper engine operation.
For this vehicle, we will adjust the valve clearance. Changes in valve clearance can make engine operation unstable, so we adjust it to the correct specification.
Parts scheduled for replacement
Parts carefully selected by Classca
- Vacuum joint
- Spark plugs
- Timing chain case gasket
- Timing chain case oil seal
- Chain slider pad
- Rocker cover gasket & seal set
- Valve clearance
- Stem seals
- Thermo amplifier
- AC resistor
Clutch
This maintenance replaces worn hydraulic and consumable clutch components to restore proper clutch operation.
Parts scheduled for replacement
Parts carefully selected by Classca
- Clutch master / AP
- Clutch master inner kit
- Master base gasket
- Rod pin & snap pin S
- Hose & gasket
- Release cylinder Borg & Beck
- Clutch release inner kit
- Clutch fluid
Brakes
Wear and age-related deterioration of brake parts can reduce braking force or cause abnormal noise. We replace worn components to restore proper brake operation.
For the rear wheel cylinders, we use Japanese-made rubber cups as a measure to reduce brake fluid leakage compared with genuine parts.
For this vehicle, we will replace the brake master cylinder. Because poor hydraulic pressure generation affects braking performance, replacement restores braking force.
Parts scheduled for replacement
- Wheel cylinders
- Brake master cylinder
Fluids and Other Consumables
Replacement / replenishment scheduled

- Drain gasket
- Oil element
- WAKO’S Seal Coat
- Brake & clutch fluid
