that to stop. The "hiss" means
there is still some pressure left.
Then continue to slowly turn
the cap and remove it.
2. Fill the reservoir with the
proper mixture of coolant and
clean water up to the FULL
COLD mark.
3. With the pressure cap off, start
the engine and let it run until
you can feel that the upper
radiator hose is getting hot
(watch out for the engine
cooling fan).
4. If the level in the surge tank
has dropped, add more of the
coolant mixture to bring the
level back up to the proper
mark.

5. Then replace the cap. Be sure
the cap is tight.
When the engine and cooling
system have cooled down, check
the coolant level again. If the
coolant is not at the proper level,
repeat steps 1 through 5 again. If
the coolant is not at the proper
level when the system cools down
again, have the vehicle serviced.
