GMC Savana

The history of this model began in America and the progenitor of the modern Chevrolet Express was the G-Van 20, G-Van 30 and other buses of the American market. The General Motors concern to this day successfully produces cars of the same class, such as the GMC Savana, a great variety of EXPLORER, STARKRAFT, DEEP, WORKVEN trim levels with a high roof with a low roof, all-wheel drive and one bridge are widely represented on the market, these cars can serve as an office on wheels , and be used in work and when transporting people and can truly be considered family cars because of their large capacity and comfortable and convenient interior.


Despite the fact that the GMC Savana have proven themselves to be reliable and safe cars, like any other brand, they have weaknesses and typical malfunctions, knowing about which and properly undergoing maintenance and routine maintenance, the operation of this luxury car will not cause problems and will bring real pleasure.


Cabin filters were not installed on all CHEVROLE EXPRESS and GMC SAVANNA cars, this problem is easily solved by introducing a standard installation kit with filter elements.


The data have a large mass and a powerful engine, usually 5.3 liters, but the size of the brake disc is quite small


If you prefer an active ride and high speeds, then it is better to replace the regular brake discs and calipers with a reinforced system with six pistons and a 385 diameter brake router.

Since GMC SAVANNA vehicles, especially those with a high roof, have a large windage, we recommend installing a rear anti-roll bar with additional shock absorbers to improve comfort and safety. and also to avoid buildup.


The rear suspension is spring and since the car is heavy, the weak point is the intermediate leaf springs, which can burst if a stone or dirt gets between the sheets. It is very easy to avoid this breakdown and replace the springs; it is enough to wash the springs from dirt with a strong pressure of water with a high-pressure washer every time you wash the car. Repair and maintenance is not an easy task as it requires special diagnostic equipment, high capacity lifts and of course the experience of mechanics.


The engine and automatic transmission are very afraid of overheating, so you need to monitor the cleanliness of the radiators and prevent them from being polluted with poplar fluff and dirt. Cleaning of radiators is carried out only with a complete disassembly and dismantling of the air conditioner radiator, as well as with subsequent refueling of the air conditioner.


On cars until 2008, the weak point was the transfer case (transfer case), since the filler plug of the transfer case was slightly below the prescribed level, and when changing the oil, especially in non-core services, the mechanics did not know that the prescribed volume is filled into the transfer case not only through the filler plug, but an additional 0.8 liters is added through the speed sensor, and thus the lack of oil, when changing the oil in the transfer case, led to its complete destruction.


In 2009, they released a transfer case of a new type, which differed from the previous one only in that the filler plug of the transfer case was 3 cm higher. transfer case (transfer case) in our warehouses. Proper and timely oil change – according to technology, solves all these problems.
