  1. If it's like my '36 Pontiac, there is a metal shielded wire that runs the length of the steering column, with a button on the upper end and a GM connector on the lower end. These typically wear where the cable exits the steering column, short out, and cause the horn to blow at inopportune times. You can get a new wire from Rhode Island Wiring Supply. Send it you old one and they will attach the connectors for you. Just retake off the horn button, disconnect the lower end, and pull the wire out.
  2. The steering column shift lever on my automatic '66 Galaxie squeaks. It seems to originate behind or within the gear indicator on top of the column. I shot some silicon down there, but no change. Any ideas on what to try next? Thanks!
  3. I changed out the neck of the radiator years ago and fit a 3-4 lb. cap to it. It's always worked very well. As you say, these radiators are not intended to be filled. I do believe combustion pressure is getting into the cooling system, but can't figure out how/why that is happening. Any possibilities come to mind? Thanks.
  4. I'm losing coolant in my '36 Pontiac flathead six. There are no leaks on the garage floor. The thermostat isn't stuck. There is no water in the oil. The exhaust shows no sign of steam. The head gasket is intact. The engine runs beautifully with no misses, backfires, lugging, or other signs of mis-functioning. If I fill the radiator half full, it will run at 160-180 on a very warm day for 30 minutes or so; then coolant will be forced out of the radiator overflow tube. (It's pressurized to 3-4 lbs) I took the head off. All the valves have a nice white powdery look, but one plug is black (the others white/light brown). That cylinder (#5), also shows some black deposit on the combustion chamber. These cars do have a water distribution tube, but it was replaced 25 yrs ago when the engine was rebuilt. With modern coolant rust inhibitors, it should still be intact. Any thoughts on what the problem is would be much appreciated. Bob Shafto Member #800-555‬
