Disadvantages of the GM L36 engine
First of all, this series of engines is well known for their frequent coolant leaks.
A leaky gasket beneath the intake manifold is typically the cause of the leak.
Additionally, the plastic pipe beneath the generator bursts and is swapped out for a metal one.
Additionally, a crankshaft position sensor, coils, and spark plugs have limited resources.
These engines were the subject of a recall campaign in 2009 because of the fire risk.
