Bleeding the Cooling System
3. Open the hood.
4. Remove the coolant pressure
cap carefully.
5. Slowly pour coolant into the
filler neck until the coolant
level reaches the bleed return
hole on the inside of the filler
neck. Leave the pressure cap
off.
6. With the cap off, start the
engine and allow it to idle.
7. With the engine idling,
observe the coolant level in
the filler neck. Make sure that
the coolant level in the filler
neck is always visible. When
the level falls, add coolant. A
rising level is acceptable.
NOTE: During bleeding, air pockets will bubble to the surface. Add coolant
after these air pockets have surfaced, making sure that the coolant
level remains visible in the filler neck.
8. With the engine idling, and while making sure that the level in the
filler neck remains visible, observe the bleed return. If the system is
self-bleeding properly, coolant will be pumped out of this hole.
NOTE: Coolant flow may be erratic (spitting, misting) for the first few minutes
of bleeding, but as long as the procedure is followed and coolant is
visible in the filler neck, the system should bleed properly.
