Harman Motors mechanical repairs workshop

Complex mechanical repairs to sophisticated high-performance engines and mechanical systems are our bread and butter at Harman Motors. With our depth of knowledge and experience we can get you back on the road, confident that your vehicle has been restored to specification.

 

Engine and transmission rebuilds

Engine rebuilding

The signs that an engine rebuild is likely to be necessary are:

  • Significant loss of power

  • Burning a lot of oil

  • Catastrophic internal damage due to sudden loss of oil pressure, overheating, or a timing belt or timing chain failure

  • Otherwise, the engine might need refreshing if it has a very high mileage, which is often the case with classic cars

If you have any of these signs or your car is undrivable, get in touch to discuss your engine rebuild options.

 

Transmission rebuilding

The signs that a transmission needs rebuilding are:

  • Slipping gears, where the engine revs up, but the car doesn't accelerate properly

  • Unexpected shifts in and out of gear while driving

  • A noticeable pause when shifting from Park to Drive or Reverse

  • Harsh, clunky gear changes instead of smooth transitions

  • Whining, humming, clunking, or grinding sounds

  • Worn bearings, damaged gears, or low/contaminated fluid are common culprits

  • Transmission fluid leaks

  • Warning lights illuminated

  • Shuddering or vibration when accelerating

  • Burnt fluid smell is a tell-tale sign

  • Failure to engage Drive or Reverse, or only drive in some gears

If you have any of these signs of transmission issues get in touch to discuss your transmission rebuild options.

 

Cooling system repairs

The signs that a cooling system needs repairs are:

  • Overheating - even a single overheating event can cause serious engine damage

  • Low coolant level

  • Needing to top up the coolant between services

  • Puddles or drips of coolant under the car from the radiator, hoses, water pump, heater core, or radiator cap

  • White steam or smoke from the engine bay

  • White smoke from the exhaust

  • Contaminated coolant

  • Heater not working properly

  • Stuck thermostat

  • Radiator issues

  • Water pump failure

  • Radiator cap failure

If you have any of these signs of coolant system problems get in touch to discuss your repair options.

 

Electrical system repairs

Electrical faults are among the trickiest car problems to diagnose because a fault in one part of the system can cause symptoms elsewhere. We’re highly experienced in diagnosing and rectifying electrical system faults in modern and classic cars. Common signs of electrical faults are:

  • Warning lights on the dashboard

  • Battery that frequently goes flat, struggles to hold a charge

  • Alternator failure

  • Flickering or dimming lights

  • Electrical components behaving erratically

  • Blowen fuses

  • Smell of burnt plastic

  • Starter motor issues

  • Corrosion on the battery terminals

  • Loose earth connections

  • Sensors behaving oddly

  • Bulbs that blow frequently

If you have any of these signs of electrical problems get in touch to book a diagnostic check.
