What to do/not do on a tour

Technical Information

  • Coolant Notes: New type of antifreeze is causing leaks in brass and lead radiators. The following notes are from club members:
    • I'm now use Havoline Conventional antifreeze for older auto and light trucks. This still has silicate, but much lower then the new types.
    • I'm using Prime and Advanced Auto Parts antifreeze coolants. They say "Extended life". Neither say OAT/IAT. They are both green.
    • Try "Conventional GREEN Formula" "PEAK" Antifreeze & Coolant. Its good for "All Makes and Models: 1989 and earlier"
    • CARQUEST makes a house brand antifreeze for older vehicles (ones with copper core/lead solder radiators).
    • Any conventional green antifreeze, whether PG or EG based, would be good to use in older vehicles. Most nationwide parts store chains carry the conventional green Peak antifreeze. The Sierra may be a bit harder to find, usually NAPA is the only retailer that consistently carries that product.
  • Remove a stuck Head:
    • Start the engine and warm it up to operation temp. Turn off the engine and back off the head bolts. Do not take them off. Crank the engine over a few times with the ignition off. Use a sharp putty knife and drive it between the block and head. Apply penetrating oil in the holes made by the putty knife. Clean around the bolt holes and add penetrating oil around the bolts. Keep cranking the engine and using the putty knife and penetrating oil until it pops up. If this does not work try driving a small screw driver between the block and head but be real careful not to damage the block and head. Move around the engine doing this until it pops.
    • A home made tool consisting of two old spark plugs with the porcelain removed and bolts stuck up through the holes in the plugs will provide a pulling force if a piece of angle iron is mounted on top of the studs and the spark plug bolts threaded through matching holes in the angle iron. Tightening the nuts screwed onto the spark plug bolts puts downward pressure on the studs and upward pressure on the head.
  • Spoke spacing on wheels for fine point judging
    • The article by Steve Schmauch is in The Restorer March/April 2012, pp 12-14.
    • To measure the different outer rim spoke spacing in the 30-31 rims a small paper stock card is suggested.
    • The four different spacings between groups of three spokes are: 30 KH mm, 35 KH mm, 38 Ford mm, and 43 mm Ford.
    • The article indicated we should check 5 or 6 of the spaces on each rim as some variation in spacing occurs. Read the gage that exactly fits or best fits multiple spaces on the outer rim to define the manufacturer of the rim. Your 2 options are KH (Kelsey Hayes) or Ford.
    • The 35 mm KH time period of use was 1/30 to 4/31. Other three sizes were used 1/30 to end of Production.
    • This check is only necessary for fine point judging. If you already have a straight set of painted rims, do not worry about this for tours and parades. The difference is hard to see if you have 35 mm and 38 mm spaces between the groups of three spoke sets.(A 3mm difference.) Observing the difference between the 30 and 43 mm spoke sets is easier.
  • Air Filter
    • Personally I wouldn't run any type of air cleaner. Our roads today are so clean the amount of dust you would suck up in 40 years would never wear out that engine. I think if it was necessary Ford would've put one on there. It's not like air cleaners were not invented back then. And they just didn't see any point in it and still they lasted 80+ years now without one. There are pros and cons to air cleaners on up draft carburetors. If you have fuel leaks air cleaners can trap them and can cause huge fires instead of just letting it drip on the ground. Air cleaners, no matter who made it or what type it is, reduce performance by restricting airflow. There are a few good things like obviously cleaner air in dirty environments, along with collecting air away from exhaust manifold leaks. There's probably more I'm not thinking of. When it comes down to it if you must run an air filter, the carb can be pressure balance to compensate. David at RENNER'S CORNER
