Emery:

This is interesting. Although you list my e-mail address below, I didn't
write the question.

Incidentally, you say you have the Champion RJ18YC plug in your Onan, that
number is close to the coach engine Champion RJ18YC6 plug recommended for
the 75-77 455 cid and 403 cid engines.

I'm wondering if the Champion RJ18YC is the equivalent of the AC R46S I had
as a plug number for the Onan??

How about spark plugs for the Onan. I can't find them at any of the auto
parts stores. I know I can get them from the Onan distributor at higher
cost.

I just checked my Onan and find that I purchased Champion RJ18YC. This was
looked up in a Champion book that listed generators. I believe that they
have discontinued the RJ16 plug. Purchased at AutoZone. Don't remember
price but probably about $1 to 2.

A while back someone mentioned the PermaCool maxi cooler. I can't recall
if it was just a mention or an install.

If it was an install where did you mount it? and have you been in hot
whether since?

I rerouted and double checked tranny cooler stuff today and bypassed
external ATF filter and threw out the thermostat gadget.
Temps are better, but pan temps not quite as good as with my old (I
thought inferior) tranny cooler.

After an hour's running in 80 degree sunshine the pan temp crept up to
170+/- and the temp just before the tranny cooler was about 210 +/-.
Final Drive about 180 +/-.

That's MUCH better than when filter was still inline along with the
thermostat, though it was bypassed on the inlet side. the final
impropvement was when I took my chickenwire rockguard off. (Not really
chicken wire but a facsimile

I have the cooler mounted against the cross member ahead of the rad wich
means that the lower half is fully exposed to airflow and the upper half
is exposed directly to the huge lighting holes in the cross member. The
fan is mounted behind and pulls the air. recommendation was to push the
air but I thought I'd try the above as it fits really nice.

I'm going to see how it behaves in the early morning cool and if not
satisfactory Im going to move it ahead of the crossmember, or I'm going
to get another cooler altogether. This thing is twice as big as my old
one was and seemingly only half as good :-)

No noise all day today except on occasion when applying brakes. I think
I had several sources of noise, one being the center hub cover coming
loose. Maybe I'm down to the last noise. Didn't get many miles done
today, but at least got some done [g]

BTW... 185 vs 195 degree thermostat! It seems immaterial if you
travelling in 70+ degree weather as water temp was around 195-200 which
basically would mean that either thermostat would be wide open or close
to it in the case of the 195.

time to hit the hay and get ready for an early start.

I suspect the problem is the fan clutch is still set to engage at a higher
temp. I had this problem when I switched to a 160 degree thermostat. I had
to adjust the thermostat on the fan clutch to engage at the lower temp.

The fuel gauge will read full if 1) there is no 12 volts supplied to the
changeover switch, 2) the changeover sw is defective, 3) there is a break in the
lines feeding the tank senders, 4) the plug at the chassis rail is corroded, 5)
the tank senders are open. If both tanks indicate "full", it's not likely both
senders are open. The trouble should be located at the dash panel.

I just finished trouble shooting a similar problem. The main tank was reading
full all the time. I found a break in the wire feeding the plug at the chassis
rail.
