Radiator End Tank Cracking

ModerateCooling System

Ageing factory radiators can split around the plastic end tanks, causing coolant loss that is easy to miss until the car gets hot in traffic.

Est. Repair Cost: £200–£450
Warning Signs:

Sweet coolant smell, Low coolant level, Staining around radiator seams

What to Inspect:
  • Inspect the top corners of the radiator
  • Check for dried coolant marks after the drive

Wheel Bearing Wear

ModerateSuspension & Chassis

Rear wheel bearings in particular can get noisy as the cars age, bringing a droning noise that is often mistaken for tyre roar.

Est. Repair Cost: £180–£400 per corner
Warning Signs:

Humming or droning that rises with speed, Rumble from one rear corner, Noise changes on sweeping bends

What to Inspect:
  • Drive at A-road speed and listen for a steady drone
  • Check for play or roughness at each wheel if inspected on a lift
