DESCRIPTION
Some vehicles may experience the coolant level warning light comes on even though the correct amount of
coolant is in the coolant reserve tank and radiator.
The coolant level sensor float in the coolant reserve tank (A) is deteriorated and absorbs coolant. The float gets
heavy, and sinks, causing the the coolant level warning light comes on. As a mass-production change, the
design of the float has been modified.
Customers having this concern should have their vehicle repaired using the following repair procedure.
