Disadvantages of the GM L36 engine
- First of all, engines of this series are famous for frequent coolant leaks.
- The source of the leak is usually a leaky gasket under the intake manifold.
- The plastic pipe under the generator also bursts and is replaced with a metal one.
- Also, spark plugs, coils and a crankshaft position sensor have a low resource.
- In 2009, there was a recall campaign for these engines due to the risk of fire.
