But it does has one serious flaw. The 4.6 was designed with a plastic intake manifold, and from model years 1996 to 2001, this manifold was prone to failure. The plastic is subjected to thousands of heat/cool cycles, in which the manifold will expand and contract.

Why does my air conditioner have a leaking coil?

Both coils are essential to the operation of your AC system. They also both hold the refrigerant at different stages of the cooling cycle. A leak in either coil can result in low refrigerant levels. Besides the coils, there are several components that are also responsible for transferring the refrigerant.
