Coolant brand

    I want to flush the coolant on the tC I recently bought as it has 127k miles and not sure it has ever been done.

    Do most people use Toyota branded pink coolant or is there another brand at a normal part store that is good to use. I searched coolant and all the threads I saw were old enough to ask the question again to see if there are off brands of the pink stuff now that are safe to use

    For the price the Toyota SLLC (super long life coolant) is what we use. The stuff lasts an insanely long time, anyone who takes it out and looks at the coolant system inside it's always corrosion free. There are alternative aftermarket choices but they're the same price, or close to it. And Toyota SLLC is the pink coolant. Not much has changed since a couple years ago.

    Also, you can flush it, but usually drain/fill is all that's needed. If the pink stuff is in your current tC then no need for a flush... just saving you time and still giving you 100% performance

    Thanks for the info. I will stop by the dealership after work. My hope is it is the original coolant and the previous owner did not do a flush and replace with something else.

    Assume with a drain and fill I just need one gallon?
    $20 a gallon is a good dealership price so got 2. Lucky I do have the red coolant and judging by its current shade I will need to flush (or drain and refill) Since I have 2 gallons I may drain, refill, run, drain and refill.

    I also have an issue with the warning light but will start a separate thread for that

    yeah I think the last time I got the coolant I got it for about $18 a gallon. Yeah drain/fill is the way Toyota says to do it. They say to never do a power pressure flush, since that will most likely rupture the aluminum radiator. Sounds like you're on the right track to get the coolant up to date!

    Did you check the coolant hoses? are those new? If you have any question to the age, best to replace those now and not waste that coolant. Just saying.. I went with the Toyota hoses since the aftermarket didnt have the sleeve on the lower or upper hoses. the lower one protects against anything that might fly off the drivebelt.. The upper has a foam sleeve that protects the wiring to the main 02 sensor..

    The one problem I did have, was Toyota's clamps fit all three spots but never could I get theirs to fit the upper connection of the lower hose. I went with a constant spring tension clamp from Oreilly on that one. No issues..

    just thought i'd mention it..
    I started to drain the coolant and it looked perfectly clean. Guess the previous owner had it done. In the black radiator filler neck the color was a little deceiving (kinda looked brown).

    Anyway, I closed things back up and refilled the coolant (a litter over half a gallon was drained) And I can return the 2nd gallon I bought.

    good to hear! Glad that everything is going well for your coolant change. That's what is cool about the Toyota coolant. People go 140k miles drain it out, looks clean! Yeah that black filler neck can make you think it is a lot darker than it really is.

    I usually have the 2nd bottle to fill up the reservoir and in case it "burps" the air out of the system. But hey if you're able to use 1 gallon, then hey save the $$$
