[Healeys] Coolant leak

[Michael Salter]

Hi Gordy,
   I don't think the problem is too serious. The hex nut that holds the
bulb into the radiator just clamps a flange between the threaded boss on
the radiator and the nut itself. If the leak is around the "spring"
covering the capillary tube just tightening the nut slightly may solve the
problem.
In the worst case you may need to remove the nut and the "bulb" to clean up
the mating surfaces.
Be very careful to ensure that the "spring" does not turn with the nut as
you loosen it. The little wire inside the spring is actually a very thin
tube which contains ether and if strained the tube will easily break....
proceed with caution.
