2. Then keep turning the pressure cap slowly,
and remove it.
3. Fill the coolant surge tank with the proper mixture,
to the FULL COLD mark on the front of the surge
tank. Wait about five minutes, then check to
see if the level is below the FULL COLD mark.
If the level is below the FULL COLD mark,
add additional coolant to bring the level up to
the mark. Repeat this procedure until the level
remains constant at the FULL COLD mark for
at least five minutes.
4. With the coolant surge tank pressure cap off,
start the engine and let it run until you can feel
the upper radiator hose getting hot. Watch out
for the engine cooling fans.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower than
the FULL COLD mark, add more of the proper
mixture to the coolant surge tank until the level
reaches the FULL COLD mark.
5. Then replace the pressure cap. Be sure the
pressure cap is hand-tight and fully seated.
