'07Camry hybrid_U (L/O 0610) Checking the coolant level If the coolant level drops within a short time after replenishing, there may be a leak in the system. Visually check the radiator, hoses, coolant filler cap, radiator cap and drain cock and water pump. If you can find no leak, have your Toyota dealer test the cap pressure and check for leaks in the cooling system. CAUTION To prevent burning yourself, do not remove the radiator cap when the hybrid system is hot. Coolant type selection Use of improper coolants may damage your cooling system. Only use "Toyota Super Long Life Coolant" or similar high quality ethylene glycol based non−silicate, non−amine, non−nitrite, and non−borate coolant with long−life hybrid organic acid technology. (Coolant with long−life hybrid organic acid technology is a combination of low phosphates and organic acids.) Coolant reservoir for engine Coolant reservoir for inverter, traction motor and motor generator Look at the see−through coolant reservoir when the hybrid system is cold. The coolant level is satisfactory if it is between the "F" and "L" lines on the reservoir. If the level is low, add the coolant. (For the coolant type, see "Coolant type selection" described below.) The coolant level in the reservoir will vary with the hybrid system temperature. However, if the level is on or below the "L" line, add coolant. Bring the level up to the "F" line. Look at the see−through coolant reservoir when the hybrid system is cold. The coolant level is satisfactory if it is between the "FULL" and "LOW" lines on the reservoir. If the level is low, add coolant. (For the coolant type, see "Coolant type selection" described below.) The coolant level in the reservoir will vary with the hybrid system temperature. However, if the level is on or below the "LOW" line, add coolant. Bring the level up to the "FULL" line. 357 2007 CAMRY HV from Oct. '06 Prod. (OM33749U)
