It was the first warm Saturday of spring. Gus Wilson was enjoying the
weather and idly eyeing his assistant Stan Hicks - energetically swabbing
the windows of the Model Garage - when the Triumph came in.
With a distinctive brrrrp as it was smartly downshifted, the TR-3
roadster zipped past the gas pumps toward the wide doorway.
What caught Stan's eye were two very blonde young ladies in identical
snug-fitting sweaters and slacks who popped out of the little car and headed
"This might be double trouble," Gus said with a grin, as he indicated
with a pointed finger that Stan should stick with the windows, "but I'll
He'd recognized the girls - the vivacious Griffin twins, both married
"Oh, Mr. Wilson, you've just got to help us," the twin who'd been driving
pleaded as she brushed aside windblown hair to reveal a concerned but
strikingly pretty face.
"What we mean is, how can we possibly enter the rally tomorrow with this
stupid thing heating up this way?" the other twin asked.
"Okay, girls," Gus said, "one of you tell the story."
"All right . . . I'm Chris - she's Carol. My husband, Bob Fletcher,
bought this TR - 3 so the four of us could take part in all the rallies this
season. Carol and I were going to enter this car, while Bob and Mike Lanfair
- Carol's husband - will be entering Mike Lanfair's Oldsmobile."
"The TR - 3 is a classic, and it looks like you got yourselves a sharp
one," Gus observed.
"Maybe. But we're just furious with this car - and Bob! We think he
bugged it. Or won't fix it, on purpose." Chris's long lashes flew upward as
her eyes widened. "I mean, how can we concentrate on speed, time,
instructions, unknown checkpoints, and all that in rally tomorrow if we have
to worry about a nutty heat gauge that keeps bouncing back and forth like a
Gus knew Chris's young husband, Bob Fletcher, a mild-mannered test
technician with a local electronics firm. Gus recalled he'd stopped in just
a few days before to buy some wheel bearings and seals for a do-it-yourself
repair. Sidling around the girls, Gus opened the hood and looked in on the
little four-cylinder engine for any obvious signs of trouble.
"I can't imagine Bob deliberately doing what you say he has," said Gus.
"Mr. Wilson," Carol said, wagging an accusing finger under Gus's nose,
"you just don't know what Bob and that awful husband of mine would do to
beat us in that rally!"
Gus avoided escalating the argument that was obviously brewing. The
engine did not appear to be overheated. It showed signs of recent care. A
look in the radiator showed clear, fresh antifreeze, and no traces of scum
or rust that could be the tip-off to a clogged cooling system.
The nonelectric capillary-tube-type temperature indicator appeared sound
at first glance.
"The heat gauge goes up and down, up and down." Carol Lanfair's brown
"Bob says he checked it and it worked perfectly. Maybe he did, but I
don't think it acted this way when he bought it a week ago."
"Why don't you let me drive you girls home? I can see how it acts, and
talk to Bob. No use checking anything he already has."
"Oh no - they think we went to the grocery!" Carol pleaded, then reversed
herself. "No, by golly, we'll show ‘em. Come on, Mr. Wilson!"
Gus shoehorned himself into the small car, relegating one twin to the
cramped, rear bench.
Through the gears, and they were gone.
"Talk about the privileges of rank. Two blondes, a sporty roadster, and a
spring morning," Stan muttered, as he tossed his sponge into the bucket.
The trip confirmed the twin's story. Gus agreed the heat indicator would
be distracting for hours of gauge watching.
Identical twins couldn't have picked more unlike mates, Gus observed as
they wheeled into the drive at the Lanfair home. Carol's Mike was lanky,
blond, and sharp-featured. Chris's Bob was pudgy, dark, and round-faced. The
only similarity was their grimy shirts and hands, and their dumbfounded
expressions as they backed away from a sporty '64 Olds in the drive and
stared at the arriving entourage.
"Gus Wilson, what the heck are you doing here?" Bob asked uneasily.
"Never you mind, Mister Fletcher," Chris snapped, "He's going to fix the
car so we'll have a fair chance of beating you two connivers in the rally!"
"But . . . but," Bob searched carefully for the proper words, "honey,
that gauge acting up wouldn't hurt anything. Honestly, I didn't bug the car
"Well! How would you like it if one of your instruments at work flopped
around while you were making an important test?" Chris inquired acidly.
"Okay, okay," Bob agreed. "Let Gus have a go at fixing the Triumph. Right
now we've got our hands full with the Olds. You think you've got troubles
with a heat gauge? We won't have a chance in the rally. This speedometer is
all screwy - acts like it's slipping or something."
Peering into the Olds, Gus saw that the two men had shot lube into the
top end of the cable.
"That speedometer was rebuilt and calibrated only a few months ago,"
muttered Mike. "It can't be haywire."
"Hah," Carol gloated, "now maybe we have an even handicap for the rally."
"Look, everybody," Gus suggested. "Let's concentrate on fixing both these
handicaps before tomorrow's rally."
The tension eased as Gus got Bob involved in telling just what he'd done
in checking out the second-hand TR-3.
"Last week, after I'd bought the car, I went over everything I could
without a service manual.
You know - points, plugs, lube job, and all. I checked the hoses,
flushed the radiator, put in new antifreeze, everything. Gus, that cooling
system is as clean as a whistle. Oh yes, I put in a new thermostat, too."
"Was the old one shot?" asked Gus.
"Nope, there wasn't one in it."
"Well, that will give me a start," Gus said. "I'll take it to the shop
and see what I can find.
Now, about the Olds. Didn't you buy parts from me for a wheel-bearing job
on it a few days ago?"
"Sure did," Bob agreed.
"Funny, too," said Mike, "it was only when we took it for a road test,
after installing them this morning, that we noticed the speedometer
Gus chuckled. "I suspected that, and I think I know what's wrong. Your
car has a speedometer driven off the left front wheel instead of the
transmission, like most. The cable goes through a hollow wheel spindle. The
square end of the cable engages a square hole on a stand inside of the
bearing dust cap."
"Yeah." Mike Lanfair's blue eyes lit up. "I remember seeing that."
"You just may have cocked the dust cap slightly, allowing the drive lug
to not fully engage. That could cause the slippage," Gus went on.
"Check it out."
Driving back to the Model Garage, Gus watched the pulsating heat gauge.
He thumped the glass in case the mechanism was bound up - to no avail. One
thing puzzled him: Why was there no thermostat in the car when Bob bought
The first thing Gus did was drain the radiator and remove the
temperature bulb from the side of the little cast-aluminum water-outlet
elbow fastened between the front of the cylinder head and the short top
radiator hose. He wanted to double-check Bob's report on the gauge.
Alternately dipping the bulb in hot and cold water confirmed that the
"If the gauge is okay, and the cooling system is clean, what can it be
but a bum thermostat," Gus asked himself. Even a new thermostat could be
Quickly Gus removed the bolts holding the flanged front end of the elbow
to a similarly flanged hose adapter. He knew he also had to unbolt the rear
end of the elbow from the head to get at the stat, because the very short
hose and the body edge directly over the flanged joint allowed no room for
maneuvering. Lifting the elbow from the head exposed the shiny top of a
brand-new thermostat - and an older thermostat in its proper place at the
front of the elbow.
"Hey Gus, you were right about the Olds," Bob shouted as he and Mike
strode into the Model Garage. "Old bear-paw Mike here didn't put the dust
cap on quite straight. How are you coming?"
"You fellows have double trouble," Gus said bluntly.
"Gee, Gus, we're sorry about how the twins acted today - real crazy."
"I'll agree they're pretty wild, but I didn't mean that. You've got
double thermostat trouble."
He held out the twin thermostats to the speechless pair.
"It looks as though in your efforts to bring the car up to snuff you
fellows didn't see the front flange of the outlet elbow. You loosened the
back end from the head and assumed there was no thermostat. It'd be an easy
mistake. Here's where it belongs," Gus pointed out, "between the flanges, at
the front end, ahead of the temperature bulb."
"So that caused the trouble!"
"The way I figure it," Gus explained, "the rear thermostat opened,
filling the elbow. The heat went up, the front stat opened. About then,
cooler water came in from the block, temperature went down, then rose . . .
over and over again."
Monday morning, Gus was checking the newspaper to see how the quartet had
fared in the rally when the phone rang.
"Gus?" It was Bob Fletcher. "Would you like to come over to our place
this evening? The Fletchers and the Lanfairs are having a little victory
"Well, not exactly, The twins won third place in their class; Mike and I
took fourth in ours.
But we all think it was kind of a family victory. You got us out of hot
water, and we'd like to show our appreciation."
"Sounds like nobody will be eating crow," Gus said. "I'll be there."
