Pontiac Astre: bodies, engines and what to know when buying
The Pontiac Astre was a compact car built on the Chevrolet Vega platform but sold under the Pontiac badge: in Canada from 1973–1974, and in the US from 1975–1977. We look at the bodies, engines and what to check when buying this rare classic.
Astre in brief
The Pontiac Astre was a rebadged Chevrolet Vega, built on the same H-body platform. It was sold in Canada from 1973–1974, and debuted in the US in the 1975 model year. The name Astre means star in Catalan — just like Vega.
Several bodies were offered: a hatchback, a notchback sedan, the Safari estate and a panel van (up to 1975). The Astre differed from the Vega with Pontiac’s grille, emblems, steering wheel and more luxurious interior trim. From 1974–1977, the cars had tail lights similar to the first-generation Firebird.
Years and changes
The only major body change occurred in 1974: due to new 5 mph bumpers regulations, the front grille changed and a larger front bumper was introduced.
In 1976, the four-leaf-spring rear suspension was replaced by a system with a torque arm spring. Production of the Vega and Astre ended in late 1977, while the estate car lived on as a Pontiac Sunbird family member from 1978–1979.
Engines and transmissions
All Astres up to 1977 came with a 2.3-litre (140 cubic inch) inline four-cylinder Vega engine with an aluminium block, cast-iron head, and a single overhead camshaft. In 1977, a 2.5-litre (151 cubic inch) Pontiac engine with a cast-iron block and head was offered as an option.
Transmissions: three- and four-speed manual, five-speed manual with overdrive from 1976-1977, and a three-speed automatic. The car has rear-wheel drive, with front disc and rear drum brakes.
What to check when buying a used Astre
Vegas and Astres were notorious for body corrosion, so be sure to inspect the wings, wheel arches, sills, and floor. Also, ask how the car was stored and if any quality bodywork was done.
The 2.3-litre aluminium-block engine was known for overheating issues and high oil consumption, so check the cooling system, oil level, and whether the engine has been rebuilt. Ask what type of engine the car has, as parts selection depends on it.
Spare parts in Lithuania are almost non-existent, but many mechanical parts are shared with the Chevrolet Vega, so you'll often need to order them from the US. There are fewer interior and trim parts, so opt for the most complete car you can find.
