I agree that 2 problems are described here.
<div><br>
<div>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.</div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>Good luck,</div>

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.<br>

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