Usage:

G3516 3RC
Engine
G3516 (S/N: 3RC1-UP; 4EK1-UP; WPW1-UP)

Problem

Some G3516 engines equipped with the LE .5g engine upgrade kit, have had the coolant line leak. The line is between the turbo outlet exhaust elbow and the right side exhaust manifold coolant return block.

Solution

A permanent resolution has not yet been defined. In instances where exhaust manifold shields are used along with the kit, ensure that no gaps are present near this hose.
