Information on repair and maintenance of Chevrolet Tahoe cars electronically
Chevrolet Tahoe is a combination of advanced technologies and the long history of the legendary SUV from the American company General Motors. Over the years of its existence, it has acquired a reputation as a powerful, reliable and comfortable car.
The SUV combines excellent maneuverability with high driving performance. It is based on the Chevrolet Silverado pickup platform, which provides it with a strong frame and reliable axles. The name of this family of SUVs comes from a lake in the USA. The model has been produced since 1992.
At first, only cars with a three-door body were on sale, and in 1995 five-door versions also appeared. The designation "1500" on the body of the Chevrolet Tahoe indicates the load capacity in pounds (although this value is rather arbitrary).
The power units were a petrol 5.7-liter V8 (258 hp) and a diesel 6.5-liter V8 (182 hp) with turbocharging, starting in 1994. The engines were mated to a 5-speed manual or 4-speed automatic transmission. The transmission had several versions, and in the American market models were offered with both all-wheel drive and rear-wheel drive.
Some versions of the Chevrolet Tahoe have the ability to engage front-wheel drive and rear-wheel drive using buttons or a lever in the cabin. However, if all-wheel drive is engaged manually, it should only be used in slippery areas to avoid damage to the transmission. In subsequent car models, the front-wheel drive is automatically connected electronically when the rear-wheel drive slips.
The SUV has an independent front suspension, and a dependent rear suspension with a continuous beam on springs, which provides good maneuverability in off-road conditions. One of the positive qualities of the car is its spacious interior. The rear door on all versions of the Chevrolet Tahoe is double-leaf: some doors are vertical, while others are horizontal, while the lower door does not lower to the floor level.
In the second generation Chevrolet Tahoe, presented in 2000 on the GMT 800 platform with a wheelbase of 2946 mm, 4.8-liter Vortec gasoline engines with a power of 275 hp were installed. and 5.3-liter Vortec with 285 hp
The car was equipped with General Motors' patented Autotrac 4x4 system, which was a computer-controlled transfer case. The Autotrac 4x4 system allowed the driver to select one of five transmission modes using a button:
- 2Hi mode was used in normal road conditions, providing fuel economy by disabling the front axle.
- AUTO 4WD mode was an automatically engaged all-wheel drive, suitable for driving on mixed roads. When the rear wheels slipped, the system automatically engaged all-wheel drive and disengaged it if necessary.
- The 4Hi mode was a permanent four-wheel drive used in snow drifts, icy conditions and other difficult situations.
- 4Lo mode was used in difficult road conditions such as driving in deep snow, mud, steep slopes and sand. Switching to this mode required stopping the car.
- Neutral mode allowed the car to be towed without the risk of damaging the transmission.
In 2004, there was a minor update to the model, as a result of which both engines added ten horsepower.
In the third generation of the Chevrolet Tahoe, introduced in 2007, the car was built on the new GMT900 platform and was equipped with fourth-generation GM Vortec eight-cylinder V-twin gasoline engines. The engine displacement was 4.8 liters and 5.2 liters, and the power was 290 hp. and 320 hp accordingly.
All Tahoe models came with an electronically controlled four-speed automatic transmission. They also had three types of pendants:
- Conventional suspension (ZW7).
- Suspension with variable springs at the rear (Z71).
- Z55 active suspension (Autoride) with electronically controlled shock absorbers
The third generation of Tahoe continued the tradition of previous models in providing a comfortable and powerful SUV with a variety of suspension options to suit the different needs of owners.
The fourth generation Chevrolet Tahoe, introduced in September 2013 and on sale in the first quarter of 2014, is manufactured at the Arlington, Texas plant. It is built on the GMTK2XX platform and is equipped with new EcoTec3 5.3L V-8 FlexFuel (L83) gasoline engines with a power of 355 hp. and a torque of 519 Nm. Rear-wheel drive or all-wheel drive are available, and the transmission is a GM 6L80 6-speed automatic.
The fifth generation Chevrolet Tahoe, introduced in December 2019, is built on the T1XX platform and equipped with a new independent rear suspension instead of the continuous bridge present in its predecessor. The suspension is equipped with Magnetic Ride Control adaptive shock absorbers (standard on Premier and High Country versions and optional on Z71).
Beginning with the 2022 model year, Chevrolet provides a 6.2-liter, 420-horsepower V8 engine on the Tahoe RST, Z71 and Premier trims. And from 2023, the Super Cruise partial autopilot function became available for top versions of the Chevrolet Tahoe.
