NOTICE:
When installing the water hose, ensure that the exhaust heat recirculation system is filled with coolant. Otherwise, the engine water pump assembly may be damaged.

(a) Using a vernier caliper, measure the free length of the compression springs.

HINT
If the free length is less than minimum, replace the compression spring.

(b) Fully insert 2 new gaskets to the exhaust manifold and front exhaust pipe assembly.

(c) Using a plastic hammer and wooden block, tap in each new gasket until its surface is flush with the exhaust manifold and front exhaust pipe assembly.
