[Farmall] water temperature in 48 super a

Thu Aug 12 14:22:16 PDT 2010

I don't think I have ever seen one hot enough to scorch a decal on the side 
of the hood.  I imagine there is an exhaust leak somewhere that you haven't 
found.  I have seen the effects of heat on the hood near the exhaust pipe. 
Usually (maybe always) it has been because of a poor fitting or badly 
installed muffler that was pushing exhaust out the joint and directly onto 
the hood.  Maybe you could start with a cold engine and soak the exhaust 
system down with very soapy water.  Then start it up and look for bubbles. 
You will have to look it over pretty quickly.  As soon as it is warm enough 
to start boiling the water off, you will be done.
