help please

[tock]

Hi Since two months I have a tractor ym1300D (my first tractor)
If someone can help me please I have 2 questions
1- my fuse box (the old model with wires) I would like to change it but I don't know the amperage of each wire - is there someone who knows this amp? please tell me from left to right for the 4 wires
2- I leave in Quebec Canada; in winter the mercury can drop to -30 Celsius while I can not keep the ratio 40/60 antifreeze/water. If I change it 50/50
could this make damage to some part of the tractor ?
thank you and sorry for my english

Nice looking tractor. 50/50 antifreeze is fine. Maybe this fuse setup could do it for you. Yanmar Tractor Parts: FUSE BOX CONVERSION - CONVERT TO NORMAL BLADE FUSES!

in winter the mercury can drop to -30 Celsius while I can not keep the ratio 40/60 antifreeze/water. If I change it 50/50 could this make damage to some part of the tractor?

I think that model has no water pump. Cooling is by convection; hot water rises (goes out the top hose to the radiator) and cold water is heavier so it settles to the bottom of the radiator.

The lower proportion of antifreeze recommended for a convection-cooled engine (40/60) is because the more antifreeze you add, the less this convection effect works. In summer you need to extract heat from the engine to the radiator, but in winter if you are not working hard then the lesser cooling ability of a 50/50 mix should be fine.

I bought a $10 pocket infrared thermometer

and I never see readings above 100C on any part of the engine (except the exhaust manifold). I suggest use 50/50 in winter, and measure temperature like this occasionally if you are worried about overheating.

Enjoy your new Yanmar!

Will the tractor actually be exposed to those temperatures? I hope you don't have to operate it in -30 C weather.

Propylene glycol has a more stable freezing point curve, and the higher the concentration of the alcohol, the lower the freezing point.

Ethylene glycol, the regular green type of coolant, actually has a lower freezing point in pure form than a 50-50 mixture of ethylene glycol and water.

If you are just going to park it for the winter, why not drain all the coolant out once it is in its parking space? Then there no freezing hazard whatsoever.

This is absolute conjecture, but I wonder if there is any information regarding how well ethylene glycol works as a coolant vs propylene glycol in non-water pump engines. Propylene glycol is more viscous, so may be tougher to use in a thermo-siphon system.

thank you for the information. great idea for antifreeze california. thank you for the fuse box but I have a Winston I bought a box blank for $ 4.00 with 6 connection available. what I need is the amperage for each of the 4 fuses on my tractor
284 internetional you asked why I need my tractor during winter; look L'hiver au Québec - YouTube That's Quebec
thank you
tock
ps: in Quebec we speack French. then apologized for my English
