624 - Fluid Loss Venting

Sine it is running fine otherwise, should I just keep filling her up and let it be (she is 40 years old now)?

Common problems with coolant:
1)Leaking around water pump bearing.
2)Rad core full of scale, require steam cleaning.
Hot water can't ciculated down thru rad so it builds up on top and goes out overflow.
3)Leaking around "O" ring at bottom of sleeves and going into engine oil.

If you think is a pressure related leak then try only putting the rad cap on loosely so pressure dosen't build.

Good luck

Just a thought and just for what it is worth, 'cause I sure don't know anything about your tractor, but you aren't over-filling that dude are you?

I've never seen a Farmall yet that wouldn't puke out the overflow if the coolant level was too high.

You should maintain the level about an inch or so above the core.

Just guessing tho,

Is that cap okay?
