Hi Brent, I removed the whole front end of my tractor, what was odd, I was lookin' for the engine block drain, the only plug I found was a braided hose coming off the side of the block, looked to be around 1/4" then it connects to the bottom of the rad just slightly above where the lower hose fits into the rad, I have no idea why this smaller hose is fed into a spigit, like whats the reason, isit supposed to aid cooling or what ?, anyhow also both hoses are different sizes, like molded this lower is larger to fit waterpump, the other end is smaller to fit rad, same with the top hose, to the thermostat housing is also about the same size as the lower hose that fits the water pump, and then the same size to fit the top rad connection, now I can understand why these hoses cost a $100 each, some or some way I'll have to make something up to tap into the lower portion, without cutting the original exspensive lower hose the top hose can stay original, I still can't figure out that braided hose from the fitting on the left side of the block to the little connection to the bottom of the rad tank, maybe someone can exsplain why it;s there and it;s purpose, anyhow, I want to install this heater/pump to the lower hose and then into the block where this 1/4" braided hose if it must be here the only way to use it is to put in a "Y" connector, this gonna' be a nightmare, but I'll figure out something, the fan belt looks a little bit fraid, is this an A width belt or smaller ?, I may as well change it while it's all apart, anyhow can someone come to my rescue, I really need some assistance, thanks in advance......AMPA
