2000 LAND ROVER DISCOVERY

Typical onset: 60,000-120,000 mi

Symptoms: Overheating with no apparent coolant leak, White smoke from exhaust (coolant burning), Milky oil on dipstick or cap, Rough idle and misfires, Coolant loss with no visible leaks

Fix: The Rover V8 block uses pressed-in cylinder liners that can slip when overheated, causing coolant intrusion and catastrophic failure. Only real fix is complete engine replacement or short block swap with top-hat liner conversion. 18-24 labor hours for R&R plus machine work.

Estimated cost: $4,500-8,000

Typical onset: 70,000-130,000 mi

Symptoms: Pink milkshake appearance in coolant reservoir (trans fluid in coolant), Transmission slipping or delayed engagement, Overheating transmission, Coolant leaks at radiator end tanks

Fix: Internal transmission cooler in radiator fails, allowing coolant and ATF to mix—kills the transmission fast. Requires radiator replacement, complete transmission fluid flush (or rebuild if contaminated), new cooler lines. Add external cooler to prevent repeat. 6-10 hours if trans survives, 18+ if rebuild needed.

Estimated cost: $800-1,200 (catch early), $3,500-5,500 (with trans rebuild)

Typical onset: 80,000-140,000 mi

Symptoms: External coolant leaks at block/head junction, Overheating, Rough idle or misfire, Coolant in oil or oil in coolant, Exhaust gases in cooling system

Fix: The Rover V8 head gaskets fail from age and heat cycling. Requires both heads off, resurface if warped, new gaskets, bolts, coolant hoses. Do timing chain guides and water pump while in there. 14-18 labor hours.

Estimated cost: $2,800-4,500

Typical onset: 60,000-100,000 mi

Symptoms: ACE warning light on dash, Hydraulic fluid puddles under vehicle, Increased body roll in turns, Whining or groaning from ACE pump, Fluid on frame rails near rear axle

Fix: Active anti-roll system uses high-pressure hydraulic lines and rams that crack and leak. Pump seals also fail. Can delete system entirely with solid bar kit (popular fix) or replace lines/pump/rams. 4-8 hours depending on extent.

Estimated cost: $800-2,200 (repair), $400-700 (delete kit installed)

Typical onset: 50,000+ mi

Symptoms: ABS, Traction Control, and Hill Descent lights illuminate together, No ABS or traction control function, May be intermittent or permanent

Fix: Usually caused by failing wheel speed sensors (shuttle valve seals deteriorate) or corroded ABS modulator connectors. Occasionally the modulator itself fails. Diagnosis with IIDTool or Hawkeye scanner required. Sensor replacement 1-2 hours per corner, modulator 3-4 hours.

Estimated cost: $200-500 (sensors), $1,200-2,000 (modulator)

Typical onset: 80,000-150,000 mi

Symptoms: Clunking when shifting from Park to Drive, Vibration at highway speed, Difficulty shifting into gear, Transfer case won't engage high/low range properly

Fix: Rubber transmission mounts collapse and linkage bushings wear out, causing excessive drivetrain movement and shift problems. Replace mounts and inspect/lubricate transfer case linkage. 2-4 hours.

Estimated cost: $400-800

Symptoms: Water pooling in footwells (especially passenger front), Wet headliner, Musty smell, Electrical gremlins (BCU gets wet)

Fix: Sunroof drain tubes clog or disconnect at firewall, pouring water into cabin and onto BCU (body control unit) behind glove box. Clear drains with compressed air or wire, reseat tubes. Dry out BCU before it corrodes. 1-2 hours.

Estimated cost: $150-350
