[Healeys] thermostat discussion

[Oudesluys]

Alan,
At least use an inhibitor, especialy if you have a mix of different 
metals in you cooling system and you practically always have a mix of 
aluminium/cast iron on the engine (waterpump, thermostat housing or 
sometimes an aluminium cil. head), sometimes even a copper head gasket 
and lead/tin/brass/steel on the radiator.
