Before you buy this car

From the engine guide

  1. Timing chain (scanner needed). Start the engine cold and listen for a metallic rattle for 1-3 seconds. Ask for Xentry live cam data and check for codes P0016, P0017 and P0011. Bad: a rattle, any of those codes, or a chain reported as slack. A jumped chain can destroy the engine.
  2. Thermostat (scanner needed). From cold, the engine should reach about 80 C within 10 minutes, and the live reading should sit between 95 and 105 C. Read codes P0128 or P1296. Bad: a temperature that stays low, overheating, or either code.
  3. Coolant (no scanner). Check the level when cold and again after a few weeks. Bad: a falling level or coolant stains around the expansion tank.
  4. Injectors and intake valves (scanner needed). Look for rough idle, misfires, power loss and higher fuel use. Bad: a misfire code or a rough idle.
  5. Oil and service history (no scanner). Ask for oil change records. Long gaps between changes and short trips speed up chain wear. Bad: long gaps or no records.
