Well, apparently (and quite frankly), Talk  Newspaper wasn't the financial bonanza I had originally conceived it to  be.  So, until my next brainstorm this column is returned to the tried and  true format of

dispensing worthless advice.

Dear JB,
    My air conditioning is not working and it is  HOT outside.  The car is a 1998 Toyota Camry, 4 cylinder with 103,000 miles  on the odometer.  It seemed like it didn't cool quite as good as it should  have last year, but this summer it is not working at all.  I do hear the  compressor engaging, but just for a second.  Is this going to be expensive?  Wait!  On second thought, I don't care!  Just  help me fix it!

Dear Oldie,

by J. B. Griffin III.

    Your car uses the modern type refrigerant known as  R134a.  Also, most Toyotas, yours included, have a very small  capacity of refrigerant.  A pound of R134a refrigerant  is actually no more than a just pound of R134a molecules, each of which are  extremely tiny.  During the winter months the seals in your compressor, the  o-rings at the joints of the hoses and the rubber hoses themselves all shrink a

little and allow some refrigerant to escape.  Since your car contains only a little over 1 pound of refrigerant when new and if we assume that only 2  ounces per year is lost due to natural leakage then you can see that over a  seven winter period the system must be practically empty. 

The short cycling of the compressor you hear is normal.  There is an electrical fail-safe mechanism to protect the  compressor in case of low refrigerant.  I think a simple recharge will keep  you cool for a few more years.


Dear JB,
    Will you help settle an argument between my uncle  and me?  He is so stuck in the past.  He says the cars of today aren't nearly as good as the old ones and that they are just overpriced junk!  I say baloney!  Cars are much better now than  ever before.  Give me some pointers on how to convince him.
Coincidentally, I received this letter as well...

Dear JB,
    I need your advice right away.  My nephew is  all head-over-heels in love with these new tin cans.  I tried to tell him that nothing compares to the cars we had way back when.  What I need from  you is some examples to prove my point.  You know, big block Chevys, chrome  bumpers, that sort of thing.  Come on, let's blow him out of the water on  this one.

Don't you love it when people argue about things that they can't do anything about, anyway?

Ever notice if someone is customizing a newer car they never look for older technology to substitute for the new?  For example, I have seen many antique cars refitted with tilt steering wheels  and McPherson struts, but I never have seen a late model Corvette retrofitted  with knee action suspension.  Ok, uncle, I can see that rose colored  glasses fit you the best.  Of course, it may seem from this distance that a 1962 Chevy Impala SS convertible is a much better  chariot than any of this stuff we have today, but let me ask you, "Have you  driven one lately?"  Occasionally we get an old car or pick-up  truck in to work on in our shop.  Let me tell you, cars have come a  long way.  Oh, the old factory hot rods take off fast enough, but try to  drive one at 70mph on the road.  They don't handle well, they don't ride comfortably and they don't stop well.  In fact, in a hard stop  they are all over the place with at least one brake locked  and skidding and you wonder if it is going to stop at all.  Additionally, where is the cruise control?  How about the air  conditioning?  The power mirrors? Ever notice how dependent we have  become on the passenger side mirror to navigate traffic?  Where is  it?  Bias ply tires make me feel like the steering wheel is only there to suggest direction to the vehicle.  It seems to wander pretty much where it  wants.

Undeniably, cars have lost a lot of  the sense of freedom once designed into them.  As safety features  become more prominent and the car seems to do more of the driving for us I guess this is the price we have paid.  Yet, try to compare any of yesterday's vehicles feature-by-feature with a new Impala effortlessly navigating rush-hour traffic at 70mph, air conditioning on, cruise set,  CD's or DVD's playing all while turning in an impressive 34mpg and you will  be hard pressed to make your point.
