Aston Martin DBS (1970)

Problem Overview

Overheating is a less typical problem identified in a 1970 Aston Martin DBS, potentially caused by a faulty radiator, malfunctioning thermostat, or a problem with the water pump.


Diagnosis

Identification is the first step. Check the car's temperature gauge while it's running. If it's constantly high, or spikes after a short time, then your car is overheating.


Tools Needed

  • Socket and Ratchet Set
  • Phillips and Flathead Screwdriver
  • Drain Pan
  • Replacement Thermostat
  • Replacement Radiator (if necessary)
  • Replacement Water Pump (if necessary)
  • Coolant/Antifreeze

Procedure

  1. Remove the radiator cap after engine has cooled down. Check the coolant level, add if necessary and check for possible leaks.
  2. Start the car and let it run until it reaches its usual operating temperature.
  3. If the engine overheats quickly, the problem most likely lies with the thermostat. To replace, locate the thermostat housing by following the upper radiator hose to where it's connected to the engine. Use your socket and ratchet set to remove the bolts from the housing, and replace the thermostat.
  4. If the engine takes a normal amount of time to heat, but then gets too hot, the issue may be with the radiator. Check for leaks, and check the fan to make sure it's operating properly. If any damage is identified, replace the radiator using your socket set and screwdrivers, and refill with coolant.
  5. If steps 3 and 4 don't fix the problem, your water pump might be the culprit. This is the most complex option; access to the water pump typically requires removing many other engine parts. If you are not confident handling this complex job, it's recommended to take the Aston Martin to a certified mechanic.

Tips and Pitfalls

  • Ensure the engine has cooled completely before attempting any fixes to avoid burns.
  • Avoid over-tightening bolts when replacing parts.
  • Always replace the gasket when replacing the thermostat.

Conclusion

A skilled mechanic can effectively diagnose and solve the overheating issue in a 1970 Aston Martin DBS using this guide. Always remember, safety first!
