1948 8N Front Mount Coil

I have a question that I hope someone may be able to answer.
I have a 1948 8N with front mount distributor. Out mowing, the tractor blew the top radiator hose. All of that hot coolant blasted down onto my coil, and into my distributor. I changed the hose, replaced head gasket (it had been bad before this) changed water pump, points, condenser, rotor cap, dist cap, new plugs and wires. Once I cranked it back up, it seemed to run fine, until it reached operating temp, it started to cut out, and even died. After sitting for a few minutes, it started again. Here is my question...could the coolant have damaged the coil? I did not change it when I changed everything else. Could that hot coolant have caused damage to the coil? Amy help would be appreciated.
 
" could the coolant have damaged the coil? "

Probably not.

Check for spark as soon as it stops running, not 5 minutes later. (see tip # 13)

Get out your adjustable gap spark checker * , open the gap to 1/4", hook it up, turn the key on and crank the engine. Does the spark jump 1/4"? Post back with the answers.

And do not buy a new part for the tractor until you can answer this question: how do I know the part on the tractor is defective?


* Don't own an adjustable gap spark checker? Buy one! Not a test light! Until then, take an old plug, open the gap 1/4" ground it to the head & look for spark. It?s not the color of the spark that counts; it?s the distance it jumps.

lc911 ,I would say that it is unlikely that it did any harm to the coil.But antifreeze residue can cause the spark to jump to unwanted places in the cap and coil.Remove the coil,cap and rotor and clean them well with hot soapy water and rinse and dry in the warm sun,also check inside distributor for anti residue.
 
I changed all of the internals in the distributor, after cleaning it all out. The coil was the only thing not changed.
