Est. Repair Cost: £500–£800
Warning Signs:

Overheating, Oil/coolant mixing, Loss of heater performance

What to Inspect:
  • Check the oil filler cap and expansion tank for contamination

Buying Tips for 2003–2005 Rover Streetwise

  • Check the K-Series engine for head gasket failure symptoms: coolant loss, overheating, and oil/water mixing.
  • Inspect the chunky plastic bumpers for severe fading or poor fitment, as they are easily damaged and hard to replace.
  • Look underneath the plastic wheel arch extensions for hidden rust on the metal arches.
  • Test the heater blower resistor, which frequently fails, leaving the fan only working on the highest speed.
  • Check the front suspension; the raised ride height means it uses specific springs that can be harder to source than standard Rover 25 parts.
  • Ensure the tailgate wiring loom isn't frayed where it passes between the body and the boot lid, causing lighting failures.
