  • Yes, like Kevin said, now's the best time to replace both upper and lower radiator hoses and clamps. Hoses will become petrified after years of hot and cold temps. New clamps will do wonders too; the OEM type work best and when you install them, ensure the screw/hex is visible and accessible for future use. Here's a picture of the OEM upper hose and thermostat. The hose band is not listed in ANY of the MPC's, and the hose is listed as 9N-8260 at 7.56" long, (which would be for the non-pressurized radiator) and the 2N-8260 at 10" long for the pressurized radiator. If the band was part of the upper hose, then it should be listed as an assembly. In the '52 MPC, the thermostat is listed as an assembly, p/n 9N-8575-A1. the A1 indicates there would be two versions/suppliers. All the MPC's show the rectangular-type thermostat so when was the pointed one issued and was it the A2 version? I don't see any 'extra holes' drilled in this example, but it's your tractor so have at it with your Black & Decker. I never had to, plus, tell me how does one gauge if extra holes do anything? There's no temperature gauge... just sayin'...

  • The hoses are new as in just a few months old

  • Buy a new top radiator hose. It's probably been 20 years or more since it was replaced. It's a lot easier to slide a t-stat in a new hose than an old one that has gotten hard as cement.

  • Amen, on drilling the 1/16 hole in the thermostat----when I rebuilt the engine on our 1941 9N I install a new thermostat in the top hose (Yes, I turned it the right way), and also a a new 4lb radiator cap. When the thermostat opened a rush of pressure came from the engine that forced about 1/2 the antifreeze out on the ground. I tried it again and it did the same thing---the tractor had been run over 60 years without a thermostat, so, I took it out and threw it in the trash. If I had drilled a small hole in the thermostat, it would have eliminated the problem---lesson learned, Dennis.

  • Re: thermostat
  • I agree that drilling a small hole in is very beneficial. It will improve it's performance.

  • Re: thermostat
  • You would think that the manufacturers would eventually figure that out. I also drill a small hole in most marine tstats. Works great.

  • Re: thermostat
  • Right you are, I spent years in the marine industry and have noted that. The early original N thermostats had holes as well as a flat brass strap that hooked over the lower end of the radiator hose at the block to prevent upward migration.

  • The pointed end goes to/points to the radiator. Click on the LINK below from our HOW-TO's forum.

  • The spiral end goes towards the engine.

  • Re: thermostat
  • You might also drill a small 1/16" hole in it to allow a small amount of water to trickle through as well as an air bleed upon initial installation. That hole also allows a slight heat transfer and lessens the temp spikes during normal operation.
    Stat open without having to go too high to get heat transfer to the bulb.

  • Re: thermostat
  • Does the hose get cut and put on both side of the thermostat or does the thermostat shove in the hose thanks Thad

  • Re: thermostat
  • Do not cut the hose -how would you splice it back together? I don't agree with drilling any extra holes in it either, but do what you want. Some fellas install the t-stat, open end nearest engine, then once clamps are tight, take a wire tie and secure around the hose to keep it from creeping up towards the radiator once it goes into use. You can search the archives here for many saved discussions on the thermostat.

  • Re: thermostat
  • Thermodynamics are fun to watch on a temp gauge. Temperatures climb, metal piece stretch, that sudden blast of cool water and the temp gauge falls like a rock.
    A few hundred times and you start to wonder why the imports all have piddle valves installed on stats and why the higher priced starts typically have piddle valves?
    That is the small stem that goes through the hole in the face of the stat. I just drill the hole and save a buck or two.
    It's your toy.

  • Re: thermostat
  • Remove the hose and slide the t-stat in it.
