I have a 1949 8n. I have rebuilt the entire tractor, new radiator, water pump block, etc... I completed the project in 1995. During the restoration I put a thermostat in the top radiator hose. About a week after I put the tractor back together, I apparantley warped the cylinder head and ended up with water in the oil pan...........I suspected a bad thermostat. After re-planing the head, I put it back together without the thermostat, and have run it regularly for the las 6 years with no problems.

The location of the thermostat (in the upper radiator hose) makes me think that unless the block gets pretty hot, it won't open. A better design came along with the Jubilees, where it is located on the block, and would warm up along with the engine. Has anyone had this problem before, and do I dare attempt to put another stat in the hose????????????

Hi alan, Running the engine cold all the time reduces it's life and also reduces power output.

Drilling one or two bypass holes in the thermostat will circulate water past the thermostat when it is closed, allowing it to constantly sense the engines temp. This will cause the engine to warm up a little slower. But on the other hand, the engine doesn't have to get so hot before the thermostat finds out about it. I haven't done this on one of these engines, so I can't give you the magic hole size. Start with a couple of 1/8' holes & go from there. At the other extreme, 2 1/4" holes are as much or more than you're likely to need. Good luck...Al English

I can see where your theory on the t-stat placement makes sense. If it is in the hose, not enough water agitation would make it up there to make it open up in time. The only way around that would be to put one with a cooler opening temperature in it, along with monitoring the actual block temp with a mechanical gauge. I'm not a big fan of running an engine without a thermostat. Sludgy oil and premature engine wear will be the result.

Later engines with the t-stat in the head benefited from plenty of water movement because of the bypass nearby.
