pause to allow any pressure to release through the overflow tube,
then press down and tum counter-clockwise to remove cap.
Points To Remember:

coolant to return from the reser ve tank to the radiator when the
engine cools. If cap rep lacement is necessary, use proper cap.
C. Check coolant freeze poi nt in the radiator. If anti-freeze is
added, contents of reserve tank must also be pro tected agains t
freezin g.
D . CooHng system leaks may p revent the reserve system from
fu n ctioning properly. If frequent coola nt additions are required,
or if the level in the reserve tank does not drop when the engine
cools, the system should be pressure-tested for leaks. Check
pressure cap by opening radiator drain cock. This should empty
the reserve tank if the cap is sealing properly.
