    Hey folks,

    I'm brand new to the forum and new to motorbike riding! Passed my test 6 weeks ago (age 37) and bought myself a lovely 2014 Street Triple 675 R, I absolutely LOVE it :grinning:

    Just a quick question if that's okay. I've just picked it up from the garage after having two new tyres (Road 6's), an oil & filter change and a full coolant flush. When asked about the coolant I've noticed he's used a non-OAT coolant and everywhere online says it should be OAT, including the manual.

    Should I flush it out again and replace with the OAT stuff? He used this one - https://www.granvilleoil.com/prodInfo?pID=364

    Appreciate any help thanks folks as I daren't ride it currently! :joy:

    Firstly contact the dealer and note your concerns because any damage that may be caused should directly fall at their door at least they should at no cost to yourself replace the coolant with the specifications recommended or they have a apprentice doing the easy service jobs that is not familiar with the bikes spec's or at least he is a scape goat that will be blamed

    Colour coding of coolants is not universal, so it is a bit of a minefield to know you have the right stuff. The main thing is that the coolant should be 'OAT' silicate free coolant. Different types shouldn't be mixed.

    That Sub Zero product does not say silicate free, so personally I'd think it should be drained, flushed and refilled with a silicate free 'OAT' product.

    I went through this whole thing when I wanted something to top up the level on my previous bike, and ended up just using de-ionised water!

    Thanks for the reply folks. It wasn't a main dealer it was just an independent mechanic like. I'm going to drain and flush it myself tomorrow, I've looked at some videos and it doesn't look too complicated I'll flush it with de-ionised water etc and then get the proper OAT stuff

    IMHO If it’s a Triumph dealer doing the servicing they should be using Triumph branded products.
    I home service my bikes and carried out numerous system flushes using 10litres of distilled water to ensure all the old coolant was removed before swapping over to the latest D2053 Triumph recommended coolant to avoid any possibility of the incompatible coolant types leading to sludge forming, gallery blockage and engine damage.

    I suspect it was not an official Triumph dealer or they would have been obliged to use the recommended D2053 coolant.

    Why go to the expense of doing this yourself it's not your mistake you are in a sense paying twice at least keep the receipt and insist the dealer reimburse you for the coolant and flush

    Hi and welcome to the forum, firstly Triumph do not make their own coolant, often coolant from different manufacturers is perfectly safe to use, the colour is only a dye, take the flushing for example, do people really think dealers use ionised water to flush systems, the amount they would necessitate using would be a giant tank full of ionised water, all that needs be done is flush it out using a hosepipe connected to a tap, with a suitable spray attachment and carefully flush through, and reverse flush out, job done. a few months back I completed a coolant change on my STRS 765, my sons Ducati Panigale 1299s and Suzuki Katana 1000, we have had no issues whatsoever, and like many others, have renewed it on countless bikes for people. It is the same with engine oil, people get fixated on colour and manufacturer, as long as it is suitable there is nothing at all wrong with whatever you choose, suitability is the criteria. I use Motul coolant and engine oil at present, but do chop and change, different engine oil colour is also only a dye added after all, it may be pink, green, orange or traditional looking, it makes no difference, if it is the right grade and specification it is good to go.

    I've used Halfords OAT coolant in the car and the ZZR for years and will use it in the Triumph when the time comes.
    To make the flushing process easier I made up a simple hose attachment that can be used in the rad filler or clamped to suitably sized hose (heater hose in the car) to flush the whole system through....

    I've just changed the oil and filter on the Triumph and gone with Shell AX7 again, mainly because I found it on offer locally but it could just as easily have been Castrol, Silkolene, Motul etc. OEM filter of course, every time.
