Used about 1/2 gallon of LLC in the past few weeks which is equivalent to 1 gallon after the distilled water is added. I suspect that this was more a case of a bad installation on the dealership's part. Not sure why the pump in the '08 failed at 89,000 miles and again at 94,000 miles. Car is still under warranty.Ībsolutely! the coolant DOES protect the pump. I specifically asked that the coolant be drained and replaced with SLL. The car is going back to the dealer tomorrow for "rework" to replace the water pump. I did add 8oz + 8oz of distilled water to bring the level up to where it should be.
#Toyota super long life coolant type manual#
The owner's manual only indicated that the following should be used: "Either Toyota Super Long Life Coolant or a similar high-quality ethylene glycol-based non-silicate, non-amine, non-nitrite, and non-borate coolant with long life organic acid technology." After an extensive search, I did find a reply from Patrick similar to what he posted above. I, too, was wondering if the two coolants were compatible. I had a gallon of LL coolant for my 1003 Highlander.
Since it was Sunday evening and he was preparing for the trip home (and the car was low on coolant) there were not too many options. I opened the hood and noticed dried fluid encrusted on the pump itself. I immediately knew that it could not be anything but the water pump. The ICE water pump had been replaced by the dealer (under warranty) in June. My son was visiting from New Hampshire with our 2008 Prius. Strange how this exact question came up a few weeks ago.
