  1. How can I tell if coolant in my oil is coming from my water pump or a head gasket?

    I own a 1973 Ford F100 with a 360 engine and automatic transmission. About two months ago I had my truck overheat because of a plugged up radiator. I replaced it with a new one and it has been running fine until recently. Now, I have found coolant in my oil. I changed out the water pump about a...
  2. Color coded wiring diagram

    Does anyone know where I can get a color coded wiring diagram for a 1973 Ford F100?
  3. 1978 Ford Shop Manual Vol 3&4 - Group 32 - Lighting System

    This will really help me out! The last couple of days I have been looking over my wiring harness and to be honest, I'm surprised the truck runs. So, I've decided to try to work on it and try to clean it up. Thanks!
  4. New turn signal switch not functioning.

    Now my parking lights will light up every time I hook up the battery, so something isn't right. Tomorrow, I'm going to rewire my new turn signal switch, but instead of using connectors I'm going to solder it all and use heat shrink.
  5. New turn signal switch not functioning.

    I have a 1973 F100, 360 motor, automatic transmission, 2 wheel drive. I just put in a new signal switch and it's not working. I need a schematic for the wiring. All the color codes matched, so I just rewired it the same. I'm guessing, I'm not getting any power to it. I tested the fuses and they...
  6. Truck won't start, bad voltage regulator?

    I finally figured out that I had accidentally reversed the "S" and "I" small wires on my starter solenoid and that's why the truck wouldn't start. So now it's running, but I need to take it out for a test run to make sure all is well.
  7. Truck won't start, bad voltage regulator?

    I have a 1973 F100, automatic transmission with a 360 engine. I went to start my truck the other day and it sounded like my battery went dead. I tried start it again and nothing , no click, nothing. I just bought a new battery for it about 3 weeks ago and I checked it and it seems fine. I even...
  8. 1978 Shop Manual Vol 1 - Section 13 - Steering

    fatherdoug, It looks as if no stone was left unturned. I now have the retainer in place, so now I Just need to put the new turn signal switch back in place. I also need to look over the neutral switch because I found the clip for it and now I need to figure out how it goes on. Thank you for the...
  9. I can't get my steering column to bo back together.

    I have a 1973 f100 automatic transmission, 360 engine. I was wondering if anyone has a schematic for the steering column. I have been trying to get my steering column back together and it just won't budge. I push the spring portion in and they to get the ring that holds the turn signal switch...
  10. 1973 360 f100 with Edelbrock 1406 Carburetor and Accel points eliminator

    I need to know what RPM am I supposed to use for setting the timing.
  11. 1973 ford f100 360 engine - No connecting wire from my starter relay on the "I" side .

    It looks like my truck does not have a primary resistance wire going to my coil. Won't that fry my coil or is the module supposed to protect it?
  12. 1973 f100 360 engine, No Spark

    One thing I noticed also and forgot to tell you , is that when I turned the key to start the truck, instead of my battery gauge showing 13.4 volts, it would go straight to negative voltage. The battery is new and is cranking fine. I have solid state ignition that is pretty old and probably needs...
  13. 1973 f100 360 engine, No Spark

    I decided to take out the heater box. Being I don't have a heater or an air conditioner on this truck and the box was blocking the left bank of spark plugs I figured it would make it easier to do a tune up which is what I am about to do. After I got it out, I tried to start it but nothing. I...
  14. Autolite 45 or 46 spark plugs

    I'm just wondering if I will have to throw away a set of spark plugs. I own a 1973 ford F100 2w drive with a 360 engine. The plugs I'm talking about are a set of Autolite 46's. The last engine I had in my truck was burnt oil so I had these spark pugs. Now I have a rebuilt engine with about...
  15. 1973 Ford F-100 360 engine overheating

    I'm pretty sure mine is a C6. I'm going to have to go at this one by myself also. My truck already sit's up fairly high, so hopefully I'll do alright.
  16. 1973 Ford F-100 360 engine overheating

    I was going to put anti-freeze in the radiator after putting on the new lower hose and I noticed that it had a large evaporator blocking my new radiator. I didn't even notice it when I was putting the radiator in. This truck hasn't had A/C since I've owned it, so I got rid of it. Now my radiator...
  17. Engine flush

    I did both a radiator flush and an engine flush. The radiator was too far done so I replaced it and it took care of my over heating problem. I did the engine flush a little differently than what was suggested, I drained the dirty oil, put fresh oil, then flushed it. My truck seems to be running...
  18. 1973 Ford F-100 360 engine overheating

    Well, I think I finally have it fixed. First, I bought a upper radiator hose and a thermostat, that did nothing. So, I bought a radiator cap and a water pump, that did nothing, I then by-passed the heater core, that did nothing. So, then I flushed out the radiator a couple of times, that did...
  19. 1973 Ford F-100 360 engine overheating

    I did, and you are right, it made no difference. I'm going to get three containers of oil with a couple of motor flushes. Flush the engine with fresh 10-30 oil a couple of times, then put in fresh oil. Hopefully, that will clean it out and it will take care of my problem. The engine starts...
  20. 1973 Ford F-100 360 engine overheating

    My mistake. I was talking about the radiator on the last post, what I think might be the problem is my motor is plugged up. I only use my truck about every 3 months to go to the dump, so it doesn't get used much, also I think I put in 30wt. oil. The water seems to be getting around every where...
  21. Engine flush

    Has any of you ever tried an engine flush? My truck has a 360 and has started to over heat recently. I have posted on here before and as I said, I have placed the radiator cap, thermostat and water pump, but it is still over heating. If you have what did you use and just how well did it work?
  22. 1973 Ford F-100 360 engine overheating

    Well, I finally put a new water pump on my truck and it made no difference, it's still overheating. So, I have changed the thermostat, radiator cap and water pump. I even by-passed the heater core and ran my hose straight from the pump to the engine and it's the same. It starts right up, I don't...
  23. 1973 Ford F-100 360 engine overheating

    No, definitely no leak. I've owned several vehicles new and old and I have never seen one build up that much pressure. The pump is on order, so as soon as I get it hopefully it will solve my problem. If not, and the radiator is still good, then I guess the last item is a blown head gasket.
  24. 1973 Ford F-100 360 engine overheating

    As soon as I get the pump put in, I will try that. I bought the radiator about 4-5 years ago from Summit Racing. It's an aluminum radiator.
  25. 1973 Ford F-100 360 engine overheating

    Thanks for getting back with me. Yesterday I took the water pump off, so hopefully I am half way there.
