I'm trying to recondition my 60,the question I have is how do I know the correct position of the heat exchange valve. A friend of mine told me I would never get it freed up, but after 2 weeks liquid wrench it finally freed up.The new ones I see for sale have hot on one side and cold on the other. This being the original valve the letters are not readible. How do you determan the correct position? I should have marked the position before I turned it after getting it free, but as you can tell I didn,t, so this why I'm asking . Thanks to my Green Buddies!! [Reply]   [No Email]

Then you should be able to figure out orientation and mark it. Straight through is Hot, 90 degrees is Cold. HTH [Reply]  [No Email]

The intake gets hot right away if its in the wintertime postion. Around here most got rusted up because they never got changed to winter use. [Reply]  [No Email]

At this point, since a new heat exchanger is only $30 or so, I would replace it. Since you say you are reconditioning the tractor rather than restoring it, I assume that you intend on using it rather than making it a trailer queen. As such, having the H and C marks would make future adjustment positioning easy and trouble free. I suppose it could be possible to determine the position of the existing one by taking temp reading on various places on the manifold while the tractor is running, but having never done it, I cannot offer any advice on the feasibility of that.
