Check a car before buyingSearch a fault codeCompare models

Common problems

  • Plastic water pump or thermostat housing leakage.
  • Coolant smell, residue, or repeated top-ups.
  • Thermostat regulation faults and slow warm-up.
  • Secondary damage from overheating or ignored coolant loss.

Symptoms to take seriously

  • Pink/white crust, sweet smell, or low coolant warning.
  • Temperature instability or heater output changes.
  • Puddles after parking or dampness under intake-side components.
  • Seller says it only needs a small top-up.

Checks before buying

Inspect around the pump/thermostat housing with a light after the test drive.
Check coolant level cold and hot, pressure behavior, and scan temperature data.
Ask whether pump, thermostat, coolant, and any hoses were replaced together.
Avoid cars driven while overheating or with mixed/incorrect coolant.
