AMC Straight-6 engine
Encyclopedia
The American Motors Corporation (AMC) straight-6
family of engines was used by a number of AMC and Jeep
vehicles from 1964 through 2006.
(OHV) and flathead
(L-head) side-valve versions.
Sometimes referred to as the 196 engine, this engine was originally designed by Nash
in the 1930s as a flathead, and redesigned as an OHV engine in 1956. The flathead version was discontinued for 1956–1957, but reemerged in 1958 as the economy engine for the "new" Rambler American
. When the engine was changed to an OHV configuration the water pump was moved from the left side of the engine (driven by a shaft extending from the back of the generator) to the front above the timing chain. When the flathead model was reintroduced it also received the new water pump. Equipped with such high quality parts as forge
d crankshaft
s and connecting rod
s, these engines earned a reputation for remarkable durability. The flathead, however, was prone to the typical flathead problem of overheating under sustained heavy load. This was from the hot exhaust traveling through the cylinder block
to the exhaust manifold
.
American Motor introduced an aluminum block version of the OHV 195.6 CID engine in 1961. It was produced through 1964. This engine used cast iron
cylinder liners and a cast iron head. The head is slightly wider on the right side than the cast iron block head. The heads will physically interchange, but the head designed for the cast iron block will need material added to its right side to properly seal on an aluminum block.
The 196 OHV requires more periodic maintenance than newer model engines. The head bolts must be re-torqued (retightening process) regularly. Factory service manuals recommend that head bolt torque be checked every 4000 mi (6,437.4 km) and to re-torque them every 8000 mi (12,874.7 km). With modern head gaskets this service interval can be extended to re-torque the bolts every 12000 mi (19,312.1 km), or every other year. The exact cause of the headbolts loosening over time is unknown, but it is believed that thermal expansion and contraction of the block, head, and bolts eventually causes the seal between the head and block to loosen. This maintenance is imperative to prevent the engine from running hot (the first sign of a blown head gasket) and thus warping or cracking the head. The cast iron liners in the aluminum block version can also shift if the head bolts are not properly torqued and the engine is run hot. If this process is not followed, then repairs will be necessary and replacement heads and aluminum blocks for these engines are now more difficult to find.
crankshaft for 1964. This design was produced in various forms through 2006. The 232 CID "Torque Command" inline six was AMC's first modern six cylinder engine.
To commemorate the engine's May 1964 introduction, 2,520 "Typhoon" cars were made on the Rambler Classic
hardtop body. Each featured the 145 hp 8.5:1 compression ratio engine, Solar Yellow body paint, a Classic Black roof, and a distinctive "Typhoon" script in place of the usual "Classic" name. All other AMC options (except engine options) were available.
The new engine replaced the Nash
195.6 CID OHV I6 in the Classic and Ambassador for the 1965 model year (this was also the first use of a six in the Ambassador since 1956).
In 1966, a 199 CID version finally replaced the aging 195.6 CID OHV and L-head engines. Road tests by Consumer Reports described the new powerplant as "a very smooth and quiet engine, which should give good performance."
Both the 199 and 232 featured a 3.75 in (95.3 mm) bore, and either a 3 in (76.2 mm) or 3.5 in (88.9 mm) stroke. The 199 was discontinued in 1970; the 232 was offered alongside the 258 CID (made by using a 3.895 in (98.9 mm) stroke crankshaft and slightly taller block) during the 1970s, but was discontinued in 1979. Increasingly stringent emission control regulations continued to decrease the engine's power output, making the smaller version inadequate as increasingly stringent safety regulations
also made vehicles heavier.
Applications:
After its midyear 1964 introduction in the "Typhoon" two-door hardtop as part of the mid-sized Rambler Classic
line, the 232 engine was adapted to fit into the smaller 1965 Rambler American
by using a special short water pump, an adaptive piece also used in the 1971-1975 Jeep CJ-5. Air conditioning was available only with the older 196 engine in the American, because there wasn't space for it with the longer 232.
Through the 1970 model year, the 232 shared a deck height with the 199 CID engines. Starting in 1971, AMC raised the deck height to produce the 258, and the 232 adopted the 199's longer connecting rods. Bore and stroke remained the same.
In 1972, the bell housing bolt pattern changed to match the larger version used on the V8 engines.
Changes for the 1976 model year included fuel economy improvements that also reduced emissions and reduced warmup time. This was accomplished by reshaped carburetor
air passages that pushed the fuel efficiency of a 232-equipped AMC Gremlin
to 30 miles per US gallon as tested by the United States Environmental Protection Agency
, compared to 24 miles per US gallon in 1975.
Applications:

The 242 cu in (4 l) engine introduced in 1987 was an evolution of the 258. It had the same 3.895 in (98.9 mm) bore as the 2.5 with a longer 3.414 in (86.7 mm) stroke giving it a displacement of 241.6 cubic inch.
The 4.0 is one of AMC's best-known engines. It was one of four AMC engines kept in production when Chrysler bought AMC in 1987. Chrysler engineers continued to refine the engine to reduce noise, vibration, and harshness
. The last in the line of the AMC inline sixes, the 4.0 is regarded as one of the best 4x4 off-road engines, and it is known to be able to go more than 300000 miles (482,802 km) without rebuilding. There are many aftermarket parts available.
When introduced, the block-mounted oil filter check valve was eliminated on the 4.0 (along with the 2.5) when Chrysler engineers standardized their oil filters. The pre-1987 engines had an oil filter adapter with 3/4 and 13/16 threads (which used a GM oil filter common to Buick, Oldsmobile, Pontiac, and Cadillac V8 engines) while the 1987-06 engines were originally fitted with a 20mm metric thread filter (later revised in 1991 for the common 3/4 threaded Mopar and Ford V8 oil filter).
The first 4.0 engines in 1987 had a RENIX
(Renault
/Bendix
) engine management system
considered quite advanced for their time. A knock sensor allowed the ECU to control spark advance in response to fuel octane and engine load. Unfortunately, there are few scan tools capable of interfacing with the system to pull diagnostics codes. RENIX systems also have no permanent memory for diagnostics codes thus making the diagnosis of intermittent problems more difficult.
The 1987 RENIX 4.0 made 173 hp and 220 lb·ft. In 1988, the 4.0 received higher flowing fuel injectors, raising output to 177 hp and 224 lb·ft—more power than some configurations of the Ford 302
, Chevrolet 305
, and Chrysler 318
8-cylinder engines, and more than any of the Japanese 6-cylinder truck engines, but with comparable or superior fuel economy.
In 1991, a Chrysler fuel injection system replaced the RENIX system, and the intake ports were raised approximately 0.125 in (3.2 mm) for a better entry radius. Chrysler also enlarged the throttle body and redesigned the intake and exhaust manifolds for more efficiency, and the fuel injectors were once again replaced with higher flowing units. The camshaft profile was also changed. The net result was an engine that made 190 hp and 225 lb·ft. Badging on most Jeeps equipped with this engine read "4.0 Litre HIGH OUTPUT." The new cam profile combined with altered computer programming eliminated the need for an EGR valve and knock sensor, but made the engine more sensitive to alterations, especially where emissions are concerned.
Small changes were made to the cylinder head for the 1995 model year. In 1996, the engine block was redesigned for greater strength. The new block had more webbing and a stud girdle for added rigidity of the crankshaft main bearings. Engines installed in 1999 Grand Cherokees carried the PowerTech name, which had been used intermittently in prior years and on other Chrysler truck and SUV engines. The name was subsequently passed on to 4.0s in the other Jeep models that used the engine, the Cherokee and Wrangler. The cylinder head was again changed for the 2000 model year to a lower flowing, more emissions-friendly design. This head was designated as "0331" in the casting number. These heads are prone to cracking and causing coolant to contaminate the oil, resulting in catastrophic engine failure. Also new for the 2000 model year, was the distributorless, coil on plug ignition system.
Output as of 2004 was 190 hp at 4600 rpm with 230 lb·ft at 3000 rpm.
The 4.0 was discontinued at the end of the 2006 model year, replaced in the redesigned 2007 JK Jeep Wrangler
by Chrysler's 3.8 L OHV V6 which originated in the company's minivans. The 4.0 engine was also made in China
, where a slightly modified version of the XJ Jeep Cherokee with 2.5 and 4.0 engines were produced alongside the Chinese-produced WJ Grand Cherokee since 2006.

4.0
The 242 cu in (4 l) engine introduced in 1987 was an evolution of the 258. It had the same 3.895 in (98.9 mm) bore as the 2.5 with a longer 3.414 in (86.7 mm) stroke giving it a displacement of 241.6 cubic inch.
The 4.0 is one of AMC's best-known engines. It was one of four AMC engines kept in production when Chrysler bought AMC in 1987. Chrysler engineers continued to refine the engine to reduce noise, vibration, and harshness

. The last in the line of the AMC inline sixes, the 4.0 is regarded as one of the best 4x4 off-road engines, and it is known to be able to go more than 300000 miles (482,802 km) without rebuilding. There are many aftermarket parts available.
When introduced, the block-mounted oil filter check valve was eliminated on the 4.0 (along with the 2.5) when Chrysler engineers standardized their oil filters. The pre-1987 engines had an oil filter adapter with 3/4 and 13/16 threads (which used a GM oil filter common to Buick, Oldsmobile, Pontiac, and Cadillac V8 engines) while the 1987-06 engines were originally fitted with a 20mm metric thread filter (later revised in 1991 for the common 3/4 threaded Mopar and Ford V8 oil filter).

considered quite advanced for their time. A knock sensor allowed the ECU to control spark advance in response to fuel octane and engine load. Unfortunately, there are few scan tools capable of interfacing with the system to pull diagnostics codes. RENIX systems also have no permanent memory for diagnostics codes thus making the diagnosis of intermittent problems more difficult.
The 1987 RENIX 4.0 made 173 hp and 220 lb·ft. In 1988, the 4.0 received higher flowing fuel injectors, raising output to 177 hp and 224 lb·ft—more power than some configurations of the Ford 302

8-cylinder engines, and more than any of the Japanese 6-cylinder truck engines, but with comparable or superior fuel economy.
In 1991, a Chrysler fuel injection system replaced the RENIX system, and the intake ports were raised approximately 0.125 in (3.2 mm) for a better entry radius. Chrysler also enlarged the throttle body and redesigned the intake and exhaust manifolds for more efficiency, and the fuel injectors were once again replaced with higher flowing units. The camshaft profile was also changed. The net result was an engine that made 190 hp and 225 lb·ft. Badging on most Jeeps equipped with this engine read "4.0 Litre HIGH OUTPUT." The new cam profile combined with altered computer programming eliminated the need for an EGR valve and knock sensor, but made the engine more sensitive to alterations, especially where emissions are concerned.
Small changes were made to the cylinder head for the 1995 model year. In 1996, the engine block was redesigned for greater strength. The new block had more webbing and a stud girdle for added rigidity of the crankshaft main bearings. Engines installed in 1999 Grand Cherokees carried the PowerTech name, which had been used intermittently in prior years and on other Chrysler truck and SUV engines. The name was subsequently passed on to 4.0s in the other Jeep models that used the engine, the Cherokee and Wrangler. The cylinder head was again changed for the 2000 model year to a lower flowing, more emissions-friendly design. This head was designated as "0331" in the casting number. These heads are prone to cracking and causing coolant to contaminate the oil, resulting in catastrophic engine failure. Also new for the 2000 model year, was the distributorless, coil on plug ignition system.
Output as of 2004 was 190 hp at 4600 rpm with 230 lb·ft at 3000 rpm.
The 4.0 was discontinued at the end of the 2006 model year, replaced in the redesigned 2007 JK Jeep Wrangler
