Coolant: Testing and Inspection
Coolant Check1. Look at the coolant level in the reserve tank. Make sure it is between the MAX mark (A) and MIN mark (B). The coolant level should be at the MAX mark only in hot conditions.
2. If the coolant level in the reserve tank is at or below the MIN mark, add coolant to bring it up to between the MIN mark and the MAX mark, and inspect the cooling system for leaks.
