    Anyone have any links to any good tutorials out there on how to do a coolant flush on a first gen 2.7L?

    1. Drain your radiator
    2. Fill up with distilled water
    3. Turn on heater and drive for a bit.
    4. Let cool, and repeat until clean, clear water is all you get. Usually a 2-3 times.
    4. Drain radiator and fill with coolant of your choice. I took into account the water in the engine and heater core and mixed my full strength coolant 60/40 with distilled water for a 50/50 final mixture.

    Yep. If you want to go a step further you can get one of these

    http://www.amazon.com/Prestone-AF-1...1462729894&sr=8-2&keywords=coolant+hydrometer to see approximately where your coolant is chemically.

    My coolant is good still but my upper and lower hoses are bad so I am just gonna do a whole flush. Question with the flush. Is there any way to get all the cleaner/water out of the system so I can just put 50/50 in??

    There's probably not much water left once you drain it, and just filling with 50/50 will get you close enough.

    Depends what coolant you plan to put back in, I used Toyota red which comes full strength and had to mix myself. I wouldn't use anything else personally.

    Not sure what the 1st gens came with standard, but the 2nd gen is the Toyota pink (not red). It comes in a 50/50 mix.

    The pink and red are slightly different formulas. Diluting red does not turn it into pink (well, it may look pink). But either should work fine.

    The first time I flushed I used Toyota Red, $40 a gallon, fuck that's that just ridiculous... so the last time I refilled from the radiator change I used some Prestone.

    Should be fine as long as it gets a good flush. Just don't mix the green with the pink.
