  • Radiator
  • My son was working on our 9n again and was working on attaching the front grill and by slamming it shut, he poked a hole in the face of the radiator, and now it is spraying out coolant. Is there any way to fix it, or should I just buy a new one?

  • Re: Radiator
  • As others said, what poked a hole in the radiator? Determine exactly where the unit is leaking from. Is it the neck, side, or the fin area? My advice is to have the radiator taken to a shop, get boiled, and soldered up. Rebuilding/restoring OEM parts are the first choice for these old tractors. Many new aftermarket parts are noted for unreliable or lack of quality control and radiators are often known for poor fitting. I had an aftermarket Cheena radiator once for my 8N and the neck was too short and scraped the hood when cap was put on. If leak is not severe, you could try oatmeal or BARSLEAK in the system. A shop can clean, test, and repair the radiator otherwise. Removing it is time consuming as hood, doglegs, hoses, and grille have to be removed first. The radiator has a petcock drain on lower unit and needs to be drained first.

  • Re: Radiator repair
  • Should you decide to try a repair, here is the method I was taught by one of the old guys. Drain the radiator, it's easiest to work on if taken out and placed on bench, table, or sawhorses, but it can be done in situ, as they say. Cut a bicycle inner tube so it's now open ends can be clamped over the inlet and outlet of the radiator. Replace cap and close drain. Clean and solder the damage, then use a tire pump to put a couple pounds of air in the tube and radiator. Spray the repair with soapy water. Bubbles or not will show whether repair is finished. If not pressure can be released quickly and soldering continued.
    I've used this technique to repair a couple dozen radiators over the years. Some rather expensive ones in the mix, even with fan gone wild damage.

  • Re: Radiator
  • I'm confused. The 9N hood was not hinged. It has 3 small rods at the top that align with 3 holes in the hood.
    If your 9N has an 8N hood, that is hinged. Even then, I don't see how "slamming it shut" would poke a hole in the radiator. Something isn't right.
    As for the radiator damage, JMOR has it right OR you can take it to a shop OR buy a new one.

  • Re: Radiator
  • I have soldered & silver-soldered many. Some with tubes so mangled by an that I cut out mangled parts of tube & soldered ends shut.
