[Healeys] Radiator

[Oudesluys]

Get the highest cooling capacity core you can get. This enables you to 
choose a sleeved thermostat that opens at a higher temperature, say 82 
degrees C, resulting in a hotter and more efficient running engine. To 
get the max out of it, do away with the fixed fan and fit an electric 
fan instead controlled by a thermo-switch that cuts in about 95-100 
degrees and cuts out at about 5 degrees over the opening temp of the 
thermostat. Use a 10lbs pressure cap that seals properly on the radiator 
and install a proper expansion reservoir.
This will allow you to drive in hot weather conditions and in modern 
stop and go traffic without any worries. Do allow for a higher 
temperature gauge reading.
To prevent scaling use pre-mixed coolant or coolant concentrate with 
distilled (preferred) or de-mineralised water and replace every two years.
Boiling, cleaning or rodding a radiator is generally not very effective 
when scale has already been firmly taken hold. Have the core replaced 
instead.
