  • 8N cooling
  • I've got an 8N with side distributor. It has a fitting on the engine block between the starter and oil dipstick. This fitting has a coolant hose going to the top radiator hose. I've also got an old 8N front distributor junk tractor with a pipe plug in this same location between starter and oil dipstick. So does this newer 8N need this coolant hose? It's really in the way to get the dipstick in and out. Any ideas? Thanks

  • Could have been used for a block heater.

  • HiYa Tommy-
    The 'fitting' is the coolant drain petcock, p/n 8115, a brass 1/4 NPT plug mounted on the block between the starter and oil filter housing see pictures. There is no hose connection to it so if you have something there, it ain't right, someone put it on probably to help facilitate draining the coolant. Most likely when the manifold was replaced as often times a manifold stud or two get pulled out and thus causes the water jacket to spew coolant out. By the way, there is also the same brass NPT petcock on the bottom of the radiator to assist in draining the coolant as well. It is also recommended to remove the petcock when servicing the starter. It helps to remove it in order to pull the starter off. Get out your essential manuals, MPC, F-04, and operators manual to see the parts and descriptions.

  • There is supposed to be a drain valve in that hole. They usually look like the same part you use to drain the radiator. No hose unless you want to stick one on there temporarily to direct the flow to a bucket.

  • Thanks guys. Today I took the 5/8 hose off petcock and plugged the hose till I can get a new top radiator hose installed. It is so easy to reach the engine dipstick now. This setup must have been for a tank heater.
