    Going to change the coolant, not done it before on this engine. I'm aware there's no bleeder valve so what's the best practice for doing it?

    Might invest in the large yellow funnel thing.

    Large yellow funnel things are brill ! ! That sorts out the only real problem which is getting an air lock which causes all sorts of problems. I used some cheap pink ready mixed in mine and was lucky as couldn't find my funnel.
    Make sure your heaters on hot so you get to the water in the matrix.

    The yellow funnels are expensive but I think worth it.

    Yeah I've heard you get idle problems etc with air in the system. You can of course just run it with rad cap off and look for burps of coolant but at the very least wastes coolant and at worse risk serious injury !

    I don't have a yellow funnel, I just let the engine idle for about 20 mins, with the heaters set to hot inside (to get full circulation). This does the job just fine.
    You'll start to see less and less bubbles popping up and of course you have to keep the radiator topped up.

    Make sure it's genuine ready mix Honda type 2 coolant! Leave he expansion cap off while running up as speedy has said put the blowers on hot and let the fans kick in a few times. So long as the coolant level is stable In the rad tank and the blowers are blowing nice and hot she should be bled up nice.

    There is no need for a flush a drain will do ,it's a entire aluminium engine and there will be no corrosion or junk to flush out.

    That depends on whether it's compatible with the previous coolant and whether you flushed the engine. If you don't know what the previous coolant is/was then it's a lot safer to flush to avoid incompatibility problems.

    5 liter of Honda coolant only cost £16 pound. Stay away from the halfrauds coolant please:sparta:.

    It has run fine for a week what are signs of incompatibility issues? I had the waterpump replaced so the majority of the old would have been replaced but imagine still atleast a litre of the old kicking round in the system as couldn’t get the whole 5ltrs in.

    Honda coolant is made CCI corporation and is the best. Halfords use BASF Glynsatin Wich is ok but is really design for the German and French car industries. All the Jap cars use CCI coolant, number one market share in Japan

    The product is called CCI golden cruiser, 20 percent global share.

    The irony being the Honda coolant is cheaper than most others including Halfords.

    It was low and only place open late on a Sunday so that's what ended up doing but should have bought a small pot for top up then the 5ltrs of the real deal with the water pump in hindsight :-/

    Worst case, a cheap silicate-based coolant can become unstable and form sand-like solids that will cause abrasion to the water pump.
