Ok to bleed the air out you fill it up and let it run with the cap off until you see the thermostat open. It will start to push liquid upward and probably some out. Then all of a sudden the level in the radiator will drop. The thermostat just opened, all the air should be in the radiator at this time. Fill her up and cap it.

If your truck has a deeper issue the radiator will never show signs of the thermostat opening it will just boil over with the cap off. You know look like a volcano.

Are you certain that is a '69 chassis and not a '79? As I understand it the wheelbase on the trucks up to '72 were the same. You have an large gap between the bed and cab indicating the longer wheelbase of the '73-'79 chassis. Also do you have 5 or 8 lug wheels? Those look like they would be 5 lug wheels making the chassis a 100 or 150 not a 250. The differences in the 100, 150 & 250 are chassis. The bodies are the same. If that is a 100 or 150 chassis you now have a 100 or 150 not a 250.

 

that's a good-looking ride.

 

Good eye there! 8 lugs, but I don't know enough about vintage trucks to be certain about ANYTHING on this truck! Going by the information given me by the previous owner...its a 65'-69'. The title reads 65', but I honestly don't know. I'm gonna post some pics.....if y'all could help me identify this frankentruck, I would be truly grateful. Also, if there are specific pics you'd need to look at to help....by all means, let me know and I'll post them! A couple more facts....the fuel tank is behind the seat, and the cab does NOT have a hole in the floor for the 4-wheel shifter, so the donor cab obviously doesn't match the rest of the vehicle.

 

Better yet, rather than random photo's...what should I take pictures of that would help to ascertain the facts????

 

Your body is '65/'66. Cab could go back to '64 but probably goes with the truck. Measure the wheelbase. 131 is correct for your truck. 133 is the '73-'79 chassis. Crawl under the back of the bed and measure the width of the frame rails. If the wheelbase is 133 and the width is 34" it is a '73-'77 1/2 F250 chassis. If it is 38" wide it is a '77 1/2 - '79 chassis.

 

I've never heard of, or seen a 16 lb. radiator cap. There is no Ford part number for any such thing.

The following is what came standard equipment in all 1958/79 Passenger Cars, F100/350's / 1961/79 Econolines / 1966/79 Bronco's:

C9AZ-8100-A (replaced B8A-8100-A) .. 13 lb. Radiator Cap (Motorcraft RS-12-A).

Beginning in 1961, the following was available at the parts counter: C1UZ-8100-A .. 13 lb. Radiator Cap-Has release handle (Motorcraft RL-12).

No such thing as an F150 until 1975.

You have an F250 4WD "Frankenstein monster" with a cab from a 1961/66 (with a step: 1961/64 F100/250 2WD/4WD, 1965 F100/250 4WD, 1966 F250 4WD / w/o a step: 1965/66 F100/250 2WD, 1966 F100 4WD).

The front fenders are from a: 1961/66 F100/250 2WD, 1966 F100 4WD, have a 36" opening radius / 1961/65 F100/250 4WD, 1966 F250 4WD, 1961/66 F350 fenders have a 45" opening radius.

The Styleside bed is from a 1964/65 F100/250 2WD, 1966 F100 4WD / 1965/66 F100/250 2WD & 1966 F100 4WD w/an 8' Styleside bed: 129" wheelbase.

1967/72 F100/250 w/an 8' Styleside bed: 131" wheelbase / 1973/79 F100/250 w/an 8' Styleside bed: 133" wheelbase.

1965/72 F100/250 2WD/4WD have 33 1/2" distance between the inner frame rails (behind the cab), as do 1973/76 F250 4WD's, 1977 F250 4WD's before serial number Y20,001.

These 1967/77 F250 4WD's are referred to as High Boys by enthusiasts, have a "divorced" transfer case.

1977 F250 4WD's from serial number Y20,001, 1978/79 F250 4WD's are not High Boys, have 37 1/2" rear frame rails and a "married" transfer case.
--------------------------------------------------------------------------------------------------------------------------------------------
All 1967 F100/350's with 352's, 1968/76 F100/350's with 360/390's came with a fan shroud as standard equipment.

There were two different shrouds, because there was more than one type of radiator.

D3TZ-8146-C (replaced C8TZ-8146-K) .. Fan Shroud / Marked on upper left corner: D3TA-8146-DA or C8TA-8146-S

Applications: 1967/76 F100/350 352/360/390 / Use with Standard, Xtra Cooling & A/C Radiators.
--------------------------------------------------------------------------------------------
C7TZ-8146-B .. Fan Shroud-Use with Super Cooling Radiator (SC/R) only / Marked on upper left corner: C7TA-8146-H or D2TA-8146-HA or D3TA-8146-JA

Same applications as above.

Note: The SC/R uses a different radiator support, has a larger opening radius, because the SC/R is taller.

 

Thanks.......now is there any way you could put that into English, or is the composite vehicle simply to complicated to be explained in anything but mathematics?

 

According to ND I am incorrect on the wheelbase for your body. Yours would be 129" which could very well make your chassis a '69. The only thing I challenge in what Bill states is I think he meant diameter instead of radius when speaking of fenders. Simply measure from the front of your wheel opening to the rear of your opening. Compare to his numbers and this will tell you what fenders you have.

 

C2TZ-16005-D Right & C2TZ-16006-D Left .. Front Fenders: 45" opening radius.

C2TZ-16005-E Right & C2TZ-16006-E Left .. Front Fenders: 36" opening radius.

See anything mentioned inre to diameter? I don't either.

I can tell immediately when I look at one a these trucks, which fenders it has. Not only is the radii different, but so are the wheel opening scallop lines. This truck has the 36" fenders.

Since we are unaware what frame was used, with an 8' Styleside bed, it could have a 131" wheelbase (1967/72 F100/250 2WD/4WD), or 133" wheelbase (1973/79 F100/250 2WD/4WD).

I ruled out the 129" wheelbase because of the large gap between the cab and bed. 1965/66 as original, the gap would be no more than 2" wide.

I owned one a these trucks (1965 F100 2WD 8' Styleside) from 3/1965 (bought it new) to 11/2009 (sold it to a collector in Sweden for 6 figures!).

Uh, included in the 6 figure sale were a: 1939 Packard Super 8, 1962 Bentley Continental Flying Spur, 1963 Galaxie 500XL HT, 1963 Studebaker R2 Super Hawk.

 

Time to draw your sword sir! A 45" radius would indicate a wheel well opening of almost 9' across and almost 4' tall. Since 4' is more than waist high on me from the ground I tend to think diameter not radius.

 

Throw down your gauntlet, unsheath your sword and challenge "The Deuce" to a as he was Prez & CEO of FoMoCo when these trucks were new.

So. he's the person ultimately responsible for what Ford parts catalogs state. But, since "The Deuce" died in 1987, using a sword on a long dead person is rather a moot point, doncha think?

Henry Ford II = known throughout the land as "The Deuce."

 

Just means I will need a sword of at least 6' in able to reach him from above!

 

No sword, regardless of its length, is necessary, The Deuce was cremated. According to findagrave.com, location of his ashes is unknown.

Now that we have throughly this thread, it's now time to return to our regularly scheduled program.

 

What I want/need to know is what engine is he working with...looked back at the posts and still don't know.

 

It's the 6.4L 390......or at least, that's what I've been told! All I can tell you for certain at this point, is that it's a big block V8. I haven't cleaned the engine, but the only reference numbers I've found so far is a part number for the carb.
