Hmmm.... all the recent cars/trucks I have owned have done this...
Ch*vy, Toyota, Honda and Ford. Never gave me any trouble. I did wonder
about it at first, but since the vehicle remained cool and the a/c
seemed to function correctly otherwise, I thought it was probably a fuel
saving measure. >>

The compressor cycles for various reasons.
The system works on a pressurized cycle; there are sensors in the system to
check pressures. if the pressure is too low, the compressor will shut off. If
the pressure is too high, the compressor will shut off.
In a normally functioning A/C system as in most cars/trucks, when the
compressor builds up enough pressure in the high-pressure side to provide the
designed flow through the valve, the compressor shuts off, because more
compression isn't going to do any good. When the pressure drops a little, the
compressor cuts back in, until the pressure rises again, and the cycle
repeats.
Why this hasn't been noticed is hard to say, but in a normal system, even here
in Phoenix on the *HOT* days (in our '92 Explorer sport and '91 F-250), this
cycling goes on all the time.
I did minor A/C work for years in my shop, and the books all described this
behaviour. If the freon levels are right, and the pressures are right, the
compressor will cycle like that (unless the system is just too small).
Hope this helps.
Bill

Subject: FTE Small - Radiator changes

Greetings and Salutations to one and all!
I was glad to find a sight dedicated to us "little folk". I own a '88
Bronco II, (I call him "Nuttin' Much") that is NOW powered by a
'78 351W with a '86 Metric OD 2wheel drive(unfortunately) trans.
The radiator I purchased is from James Duff Enterprise and a 4-core
custom for the V8 swap. The problem is the radiator is leaking and
starting to fall apart. I read in Summit Racing that it was
suggested
to someone that they could use the Ranger radiator in a Ranger V8
conversion. I also read in the catalog I received from J.D.E. that
the old 6cyl radiators wouldn't allow for enough cooling. Anyone out
there have any ideas? Thanks for your help.

Hell.. mine's worse than that! (Not the seal completely; just overall
usage.) Basically a Ot. a tankfull.

Me either but at 152,000 miles it's time for me to rebuild my tired
steed.

Certainly not the IDEAL way to do it, but yes you can just pull the oil
pan and tranny and replace the bearings/seal that way. Please invest in
some 'plastigaguge' though to make sure the bearing clearances are OK,
and also check the end play with the new thrust bearing installed. Dont
forget that a GOOD machine shop can build up the thrust surface of your
bearing if the end-play is still high rather than springing for a new
crank. (Worked for me.. had a 318 with 400+ HP that was still running
strong 50,000 later that I needed .028" reduction of play in.. and I
beat the snot outta that thing!) Put some fuel line or vacuum caps over
the end of the rod bolts when you take 'em off to prevent any nicking of
surfaces of course.

> I know I have to pull the engine

You do? Unless you're planning to have the crank machined (recommended
of course), you should be able to do it 'in-frame' if the tranny's out
of the way. (Of course the engine might be all BUT removed for
clearance getting the oil pan off..)

Hmm.. if you're planning on yanking the engine anyway and can afford it
get the head resurfaced and a valve job on it, put a quick hone on the
cyl's and a set of std. size rings on the pistons and dont worry about
it for another 50-80,000! (Although this could be done in-frame too.)
Plus if you've already had some machine work done the shop'll be more
willing to build up your thrust bearing for you if needed.

Hello,

This is interesting about the gas tank of the Explorer and a steep
incline. I happen to live on a steep hill and noticed that I always
seemed to be low on gas until I got down to the highway and drove for
several miles. Then I'd have a lot more gas than I thought!

Ken Justice

Overall pretty correct; I might add that lower overall temperatures are
obtained by letting the system cool below the point that ice would form
on the evaporator then cycling off for a moment to bring the surface
temp. back up. With the exception of GM products using a variable
displacement compressor almost *ALL* vehicles cycle when working as
designed since 1975 or so.

At approx. 95F heat index A/C systems get maxed out (at idle at least)..
It might not have been noticed going down the road or..?

Exactly.. it *should* have been cycling all along. On the days of the
MOST load it would cycle less, but now that temp's are decreasing the
cycling should increase. Try asking your Question on
http://www.ford-trucks.com//lc/lc.php?action=do&link=http://www.aircondition.com/wwwboard/index.htm to make sure I didnt drop
the ball but it seems it's OK. (Possible low charge now, but still
wondering why no cycling earlier.)

Dave,

You don't have to pull the whole engine to replace the main-seal..But
you do have to drop the tranny; its the same process needed to replace a
clutch...My recommendation is to take it to a shop..its a difficult task to
do w/o a lift, ect..

Subject: FTE Small - ADMIN: BBS info

A few list members have asked why you must "register" before
using the web BBS. They correctly pointed out that most BBS
systems don't require this. The reason is simple: spam.

Systems that don't require registering allow automated email
address harvesters into them. Registering is a process that
an address harvester cannot do. Therefore, you can safely
use our BBS without fear that you'll end up on spam lists.

Now returning you to our regular program........
