The tractor is a Yanmar diesel but, I decided to post the question here since it is more of a general than a Yanmar specific question. For the bad news. I severely overheated the tractor. The temp guage never showed the tractor to be hot. I was using the rotary cutter and noticed the engine was sounding different. I looked at the engine and noticed that the paint was starting to smoke. I immediately shut it down. I carefully removed the radiator cap using gloves and steam came out. I let it cool down and put water in it. The tractor started but sounded like some marbles were rattling around inside. So, i shut it back down. I am afraid i have cooked the engine.
I did have to add some water to the overflow bottle before i used it but, did not think to remove the cap and check the level there.(That may be my fatal mistake.)
Anyhow to my question of where to start.
I need to try to determine how much damage was done and what it will take to fix it or is it worth fixing? My first thought is to drop the oil pan and see what it look like down there. Then remove the valve cover and look in there too. I suspect that at a minimum I am looking at a rebuild to some degree..
The tractor had been using oil prior to this and the rate of consumption was seeming to increase. I also have been having to add water every time i used it but, I thought that was because the lid to the recovery tank kept popping off.. Maybe in retrospect I had a blown head gasket and did not realize it. The tractor seemed to run ok and had plenty of power too.
Anyone have any thoughts?
