G'day and congrats :applause: on acquiring your 1st Cub. It probably won't be your last :lol: they get kinda addictive.

Image to the Farmallcub.com :big smile: Forum Family. And you have come to the right place for all things Cub related. If you click on the Site Rules, Regulations, & Important Information, it will point you to :arrow: the Welcome Wagon wherein you will find links to many useful sites and topics. One of which is the Cub Manual Server. You may also wish to check out the CubFests and Gatherings Calendar 2011 to find a gathering of fellow members where Cubs, Friends and a good time is shared by all. Enjoy!.


For your questions..

1. The cooling system is a thermo-siphon system with pretty much zero pressure unlike a modern car radiator etc., As long as there is sufficient coolant (fill up until you see it or it just enters the overflow tube) and you will be good to go. This system will seek it's own particular level - as in you will see coolant come out of the overflow tube while the engine is running and then when it gets up to op temp. Once the leakage has stopped that should be it's proper level. You may need to top up once in a while. A zero pressure cap is best but if that is unavailable then a very low pressure cap - less than 7lbs is sufficient.

2. Oil - not sure what the greenish tint is. If it was coolant it would have separated after a few days so the likelihood of there being coolant in the oil is slim. That also reduces the likelihood of there being a cracked head or head gasket. Monitor it for a bit and see what happens. If while operating you smell glycol -- then I would look for a cracked head/head gasket. The reason I know that is cause I BTDT a couple three times the last year or so.....

3. I would go over all of the tractor and change all the fluids. Suggest reading the Owner's Manual for your Cub -- see following link :idea: :D

International Cub Lo-Boy Tractor Operator's Manual 9-30-57 Lubrication section starts on Page 21 thru to Page 29

Hope this helps. Others will be along to add to font. We have a lot of great folks here who really know their Cub Stuff :-:-):

Welcome, drice. As Rudy said, if it hasn't separated, it probably isn't coolant. The green could be from some additive put in by the previous owner.
I suggest you put a new filter and oil, and check it again after running for a bit.

Welcome.

I did a web search for "green color in engine oil" Came up with, it could be the result of an oil additive and "Kendall GT1 Oil, it was green".

My suggestion is the same as Rudi's - complete fluid change - see what happens.
I have an excuse. CRS.

I would change the oil, and top off the cooling system (just enough to cover tubes) and top off the hydraulic and run it a while, and check it again. If you haven't done it yet, drain the oil filter drain, if it has antifreeze in it, it will have separated in there.
