For all vehicles, check the level of the tank by viewing the lower mount on the tank. Less than 2 mm (0.08 in) (# 1) of the mounting slot should be
visible above the attaching nut. If the gap is greater than 2 mm (0.08 in), loosen the surge tank and hold in a downward position to achieve less
than a 2 mm (0.08 in) gap above the attaching nut. Tighten the bottom nut first, then both top nuts.
Tighten
Tighten the nuts to 10 N-m (89 lb in).

Verify coolant level in surge tank:
-
If engine coolant is hot, above 83°C (180°F), fill the coolant surge tank 12 mm (1/2 in) above the cold indicator mark.
-
If the engine coolant is at ambient room temperature, fill to the top of the cold indicator mark.
