LA1 L36 L67

General Motors / V6 / General Motors 60° V6 - Petrol / 3.4/3400 / LA1

Engine manufacturer

A car and its engine do not always share the same manufacturer. Sometimes the engine and other components can be borrowed from other manufacturers.

General Motors

Engine family

General Motors 60° V6

Engine series

Each individual engine series has its own design features and is installed on certain vehicles.

3.4/3400

Displacement

The more cylinders in the engine and the higher their total volume, the more powerful the car is considered. On the other hand, the more cylinders an engine has, the higher the fuel consumption.

3.4L V6

Oil capacity

Keep an eye on the oil level in the engine. If it is too low, it can cause a breakdown, because all its elements must be abundantly lubricated during the operation. If it is too much oil, it will interfere with normal engine operation and create excessive resistance.

4.0 quarts

Oil viscosity

Different engines require different viscosity grades of oil, which are specified by the engine manufacturer. These viscosity grades are typically denoted by a number and a letter, such as 5W-30 or 10W-40. The number represents the oil's viscosity at low temperatures, while the letter represents its viscosity at high temperatures.

Oil drain plug torque

When changing the oil, make sure that you tighten the oil plug strictly with the necessary torque. If you screw it in too loosely, the oil may simply leak out, or if you apply too much force, you risk damaging the threads.

18 lb-ft

Coolant capacity

Lack of coolant in the system can lead to engine overheating, which in turn leads to costly repairs. Ensure that the coolant amount is always at the level specified in the manual.

11.3 quarts

Battery size

There is a special area for the battery in your car. When selecting a battery, make sure that it will fit in its intended location and will not be too large.
