2002 Rover 25 problems

• 1.1 K8 60 hp / K16 75 hp (Rover 25, 1998-2005)

  60–75 hp

  We have not found faults specific to the 1.1, but it shares the family's small cooling circuit (about 5.5 litres in the ZR/ZS) and the head gasket's reputation; it is worth checking the coolant history before buying.^[3][4]

  With caution

• 1.4 8V/16V 74-103 hp (14K2F / 14K4F, 1995-2005)

  74–103 hp · 14K2F, 14K4F

  Technical sources describe the head failure mainly on the 1.8, but Diariomotor speaks of "all K-Series"; it is worth buying if the coolant has been looked after and there are no signs of overheating.^[4][5]

  With caution

• 1.6 16V 109-116 hp (16K4F, 1995-2005)

  109–116 hp · 16K4F

  This is one of the versions where technical sources place the change to "damp" liners, with less coolant between cylinders; Diariomotor recommends checking whether the gasket is already the reinforced one.^[4][5]

  With caution

• 1.8 16V 117-136 hp (18K4F, 1995-2005)

  117–136 hp · 18K4F

  This is the version most cited in head gasket failures; it is worth buying if it already has the multi-layer (MLS) gasket with the liners measured, and Diariomotor considers its absence a good argument for negotiating the price.^[4][5][6]

  With caution

Faults that affect 2002 cars

• High severityFrequency: CommonCylinder head and blockHead gasket failureThe K-Series' big problem is the head gasket, which can fail even below 100,000 km because of a mix of gasket design, cooling and overheating. The usual repair uses the multi-layer steel (MLS) gasket that was developed for the Freelander.
• High severityFrequency: OccasionalCylinder head and blockSunken cylinder liners and warped head after overheatingAfter overheating, the K-Series liners can end up below the surface of the block and the aluminium head can be marked or warped; then no gasket seals properly and the liner height has to be measured and restored.
• Medium severityFrequency: OccasionalCoolingCoolant leaks: expansion tank cap, rear block rail and hosesThe K-Series circuit holds about 5.5 litres, so a slow leak empties the expansion tank and causes localised overheating. The points cited are the tank cap, the metal rail at the rear of the block (corrosion), the hoses and the coolant passages of the inlet manifold gasket.

• High severityFrequency: OccasionalBrakesCorroded brake pipesIn British MOT data (1.78 million tests), excessively corroded brake pipes are one of the most repeated failures on the Rover 25: 34,685 cases, 1.9% of tests.
• Low severityFrequency: OccasionalGearbox and clutchBroken or damaged driveshaft gaitersA torn or damaged CV joint gaiter appears twice among the ten most repeated failures on the Rover 25 in the British MOT: around 31,800 and 31,600 cases out of 1.78 million tests.
