  • Thermostat
  • I just bought a new thermostat for my tractor. It didnít come with one in it. Can anyone tell me how to get the thermostat in the hose that far up. The thermostat has two lips on it one is rounded that goes in first the other is flat and sharp. I donít even think I could heat the host up that much to push it up that far. It has to go at least 1 1/8Ē up in the hose. I bought the thermostat from just8N and it said it was for my tractor. Can anyone help.
    Thanks Rich

  • The best method for installing the thermostat in the radiator upper hose is the hot water technique mentioned. Boil a pan of water on your stove, set aside, then insert a new hose to make the rubber more pliable. Apply some plain old liquid dish soap all around the outside body of the new thermostat then work your way into the upper hose from the radiator end. The unit is inserted with the pointed end towards the radiator. The original hose had a band attached to the upper end in order to keep the unit from slipping down towards the engine when system got hot. New hoses made by Dennis Carpenter have this band but if you don't have this band, you can use a plain hose clamp or a plastic wire tie. I advise to use a new hose when doing this. Rubber will lose some properties over time and harden up. That makes it more difficult to work with. I've used WD-40 to lube the thermostat for insertion a few times too. Soap and WD-40 won't do any harm to coolant. Here is an older post on the cooling system you may want to keep for reference.

  • Thanks Tim just to let you know I have a hose from Napa not an OEM one and for letting me know witch way to put it in. I was going to put it in wrong. I will try to heat the hose up in boiling water and see if I can get it in. I still think it wonít move because of the flat lip I think it will grab the rubber, but I will put a clamp there anyway.

  • Do what Steve said below OR, I just installed one in the hose on my '47 2N using my heat gun to warm the rubber. Not too hot! I used a socket slightly smaller on the socket extension. Easy as can be.

  • Heat the hose up in hot water-boiling then insert the thermostat.

  • Lubricate the inside of the hose and the new thermostat with antifreeze and then use the handle of a long screw driver to push it up and it will slide right up.I slid mine up halfway up the hose.Just make sure you install it correctly with the pellet facing the engine.

  • Re: Thermostat
  • Ok I just had Tim tell me to put the pointed end toward the radiator. That is the way you bo it on cars Iím hoping you mean the same when you say the pellet end. I do have a Napa hose not a OEM hose this might make a difference.

  • Re: Thermostat
  • You are correct. The pointed end is not the pellet side as I refered and as you stated the pointed side does goes towarsd the radiator.
