[AT] Radiator situation

Jason, I may very well be mistaken, but if the electronics are on the order of a Pertronix unit or similar, then we are talking about the use of the good old standby point actuated coils and their ability to satisfactorily use solid core plug wires.   Only the trigger itself has been altered then.I whole heartedly agree with you if using modern totally electronic (computer types to me) ignition systems.David

 With electronic ignition it's a must to use the matching coil and use carbon core wires. Anything else and you will greatly shorten the ignition's life.

That new electronic ignition may be causing problems with the coil.  Also, since the electronic ignition will create a lot hotter and higher voltage spark, the coil can be shorting out.   I have also had new name brand coils start misfiring when hot.  My last GM that used the coil in the cap had 4 coils before I put the old original one back to stop the misfire when hot...  If the engine just shut down without any misfire, pulling down, etc of that type, then it is ignition.  I would also look for a relay in the circuit.  Maybe one in the main ignition wire feeding the switch.  I spent over $400 and 6 months hunting a blower problem when it was a breaker in the line....

 Yes, but it moves the new ignition system or module up higher on the list of potential problems 
  Thanks Dennis

  Since he said he just installed an electronic ignition, we can probably rule out a bad condensor.

  Had similar problems with our oliver 77. Frustrating but found had condenser that was faulty. Joe Hardisky ryman farm dallas pa.

   I agree that 2 problems are described here.  
 Also agree that bubbles in coolant are most likely a head gasket or cracked head. For occasional use run with the radiator cap loose and that should let the bubbles escape without loosing coolant. For occasional use you can run like this for a long time. 
  My thought is the second problem of engine quitting is some electrical device getting hot and it stops working, such as a coil. When it cools down it starts working again. 
  Good luck, Dennis

 Tyler, sorry you had problems on the ride. After reading you whole post I would first assume the two issues are unrelated but... here is how they may be related.  Have you checked the timing with a timing light?  It is possible that the timing of the spark may be too early causing the spark to occur too soon. That would cause the engine to run too hot. That may be the reason the ignition is cutting out and the radiator coolant to be raising too high znxx overflowing. Sometimes it is hard to differentiate the coolant bubbles being caused by the water pump versus a compression leak.  So I would set that aside for awhile. First problem to solve is the engine cutting out. First obtain or order a temperature gauge. While waiting for it check the timing with a timing light. IF thzt is ok then check for  poor or loose connections. After getting the temp gauge installed go for a test run. Then pursue the coolant issue.

  Last Saturday, June 8, I took my Oliver 88 on a tractor ride. I have
  been on this ride for five years, and it In the first, and hopefully
  the last, year I didn't finish.
  I had just put an electronic ignition on it with a new coil, spark
  plugs, wires and cap. On the ride, I rode for quite awhile, (I don't
  remember how many miles), and stopped for a break. I started it back
  up, and we kept going. The tractor was running like a sewing machine.
  Just purring away.
  And then all of a sudden, at full throttle, I am running, running,
  running, and then it died. No smoke, no leak, nothing. It just quit.
  So, they pulled me with another tractor to the side of an elevator.
  One of the guys said, "Tyler, try starting that again. Might just be a
  vapor lock." So I pushed the button. Sure enough, it started again! It
  ran like an Oliver for another 8 miles, and did the same thing again.
  This time, some antifreeze leaked on the bottom, but it was a "drip
  drip" and then it quit. So it got towed to a guys house, of whom I
  knew, and I hopped on a people hauler to finish the ride.
  I went back, and started it, and had someone drive it onto the
  trailer for me. (Remember, I'm visually impaired). It ran fine then
  also.
  So I brought it home, put it into the shed. I took both hoses and
  clamps off, and found a half galon of coolant came out.
  Anyway, we cleaned the fittings up, put new hoses and clamps on, and
  bought some water in the gallon jugs at the grocery store. (We had to
  replace the pump in our well, and so there's a lot of rust in it now
  and didn't want to put that in). Anyway, a few days later, I proceeded
  to fill it. My father brought over a funnel that had a little oil on
  it. I wanted to clean it, but he said it wouldn't hurt. So when I
  dumped the third gallon in, it made a small screech. We realized that
  the radiator was full! It uses 4.5 gallons according to the book. It
  was filled almost to the brim. (That's too full). So then I went to
  start it. My father suggested that we leave the cap off so we could
  see what was going on inside the radiator. So we started it, and like
  always, it fired right up, and ran fine. However, I had filled the
  radiator so full, it was a wet mess. So we left it outside for the
  night so that the excess could just leak out and didn't make a mess on
  the shed floor.
  Yesterday, (Sunday) my grandpa, (The one who gave me the tractor),
  was over for a meal and to visit. Grandpa obviously had grown up on
  both an Oliver 70 Hart Parr, and an 88 like I have now. So all three
  of us went out to look at it. We checked the radiator. It had
  obviously leaked down to a "happy point." We added a pint of water,
  just to make sure it was over the core.
  So here again, I started it, it ran like an oliver the whole time.
  However, in both instances I ran it, there have been air bubbles in
  the radiator. Both times in running, there is no white smoke, the oil
  looks great, and, as my grandfather said, both hoses are the same
  temperature. I must also mention that when I had the hoses off, I
  flushed the radiator 4 times. There is also supposed to be a
  thermostat in the tractor, but apparently it never has had one since I
  have had, or my grandfather has had the tractor. It never got hot. So,
  this is what we know so far.
  1. The day of the tractor ride, it obviously got overheated a bit.
  (We are all in agreement that somehow it had to be low on coolant.)
  2. My grandfather highly doubts its the head or the head gasket,
  because the oil is fine.
  3. After 40 minutes of running each time, it didn't get overly hot.
  (The temp gauge has never worked on this tractor, but just by feeling
  the cap, it only felt "engine warm"
  3. It's not the water pump, because water is circulating just fine
  and not leaking.
  4. It isn't boiling out on the sides of the radiator or anything
  after running for awhile.
  So, why might it be bubbling? There has to be an air pocket or
  something somewhere that's causing this. The other thing that I am
  wondering is, "Did the tractor always do this, and nobody realized it
  until now, because there was no reason to pay attention to it?"
  Should a person just run it down the road at full throttle for a
  couple of miles to try to get the air out?
  What does everyone think?
  Thanks for any help, and sorry for the long post. This is my pride
  and joy, and so I want to take great care of it, as always.
  Take Care,
  Tyler Juranek
