This thread started on the Healeys list, but is most approprate here, so I
have forwarded it in case there is someone on this list who is not on the
Healey list.

I need one of you folks with a parts manual to give me whatever info you
can about the following.
1. a Sprite radiator with a metal tag on top with the numbers
ARA 92 11 65
2. a Sprite radiator with a metal tag on top with the numbers
ARA 92 43 64 This rad fitted to a AN7.
3. a radiator of unknown origin with a metal tag on top with the
numbers ARA 92 11 66. Is it safe to assume this one is a
Sprite rad also? Its appearance is exactly the same as the
other two.
What do the above letters and numbers tell? Do the last two digits
indicate year of the car?
Any help much appreciated.
P.S. What year is the AN7 car? >>

ARA92 is a part number for the Sprite radiator used for a number of years.
The second two digets are the week of the year during which it was made
and
the last two digits are the year in which it was produced. The last two
digits do not tell you anything about the car, only the radiator.
Particulary in this case. AN7's were built between Oct 1962 and Feb
1964.
(Most likely titled 63 or 64) So, none of these would have been the
original
one fitted to the car, since the oldest one was made in Oct of 1964, eight
months after production of that model of car stopped. Remember, radiators
are very often replaced, rather than recored, when a repair is needed.
They
are all, however the correct radiator for that model, and several other
models of Sprite. >>

I am not so sure that the answer is that simple. The original radiator
carried a part
number of ARA 73. With a production change at H-AN5-6889, it was replaced
by ARA 92.
The ARA 92 remained the Sprite radiator until H-AN5 production ended in
early 1961 at
50116. With the introduction of the AN6 in 1961, the radiator part number
was
replaced by ARA 241. Thus, Keith's three radiators could not have been
produced in
1964, 1965, and 1966.
Now, what the answer is, I am really not sure!

Hi Bob,
We are in agreement regarding the early (ARA 73) type radiator. Regarding
the second type ARA 92, my information is as follows;
Per Mechanical Service Parts List for AH Sprite AN5 and MK II
AKD 3566 Issue 4;
ARA 73 HAN5-501 to 6888 Note: N.A. use ARA 92
ARA 92 HAN5-6889 to 50116
HAN6-101 to 24731
HAN7-24732 on
Per Mechanical Service Parts List for AH Sprite Mk III and IV
AKD 3513 Issue 10;
ARA92 HAN8-38829 to 62374 Note: W.S.E. use ARA 241
ARA 241 HAN8-62375 to 64734
HAN9-64735 to 72033
ARA 318 HAN9-72034 on USA
77591 on except North America
N.A. stands for Not Available
W.S.E. stands for When Stock Exhausted
If you (or anyone else) has Service Parts List data which contradicts this I
would be interested in seeing it, as this is the information being used in
the current Concours Standards, and we are always looking to update or revise
information, as well as add new information.
By way of additional information;
Physical identification;
ARA 73 is the early type without side shrouds, 10 gills per inch and the
"Built by Morris Motors" tag.
ARA 92 has side shrouds, 12 gills per inch and 3 concave (non symmetrical)
depressions in the top tank. Early ones also had the "Built by" tag, ending
date for use of this tag is not known.
ARA 241 has 4 (symmetrical) more squared off depressions in the top tank.
The above 3 are all vertical flow type radiators.
ARA 318 is the cross flow type, also fitted with expansion (overflow)
reservoir.
Vehicles;
My Bugeye (build January 21-22, 1960) fits the description of the ARA 92 and
has the tag which reads "Built by Morris Motors"
My HAN8L57588 (build December 3-7, 1965) is marked with ARA 92 45 65
My HAN9L67167 (build March 29-30, 1967) is marked with ARA 241 11 67
All the "known to be original" vehicles which I have seen fit this numbering
& dating pattern.
