2.
Remove the cap from the heat exchanger and observe the fluid level.

Install the cap onto the heat exchanger.
IMPORTANT: When installing the cap, be sure to tighten it until it seats on the filler neck.

With the engine at normal operating temperature, check the coolant level in the coolant recovery bottle.
