WARNING:

To avoid the danger of being scalded, never drain engine coolant when the engine is hot.

Gasket for intake manifold collector (upper) is secured together with mounting bolt for intake man-
ifold collector (lower). Thus, even when only gasket for upper side is replaced, gasket for lower
side must be also replaced.
