    The radiator outlets on the V8 110 are different to the Perentie IME

    Hi Phil - you are correct, the radiator hoses on a Stage One V8 - are different to those on a 4BD1... (I couldn't remember if the 4BD1 came in a Stage One OR County though).

    Hi Everyone else - thanks for your replies, I shall ring my parts guy this morning and see what I can get.

    Yesterday I was checking the lower radiator hose (squeezing it) and it felt like it was breaking down on the inside of the hose. So I want to replace it - and while I am at it, I might as well get all of the other hoses. I'm not loosing coolant BUT I didn't like the feel of the lower hose..

    Cheers,
    GG.

    Update

    Hi All,

    Just to update and close this topic... My FFR has been driving great, the temp sits on about 80-82c all the time, no coolant leaks and the coolant looked to be in good condition.

    However - I have a low coolant alarm that was sometimes going off when I initially started the car. The alarm would run for 2-3 minutes until the temp came up to normal and then go off.

    I inspected the wiring, and inspected the coolant levels - Alien witnessed it and suggested that I check for an air pocket in the top radiator hose.

    When I inspected the top radiator hose, it was fine - but when I inspected the bottom radiator hose (visually and by squeezing it) - I could feel the inside of the hose breaking up... It's hard to describe but something wasn't correct.

    Hence this thread - so I purchased top, bottom, and by-pass hoses.

    Last night I drained the coolant - you can see some crap in there. I am not too worried about the film - as this bucket is used for all kinds of liquids, so would not have been 100% clean before I used it:

    I have a high water pressure at home (we need a restrictor value on the house to reduce the pressure - so I flushed the system (lower radiator pipe, water pump pipe, top of water pump housing).

    I alternated between the 3 areas, using different pressures from the hose - and quite a lot of crap came out!! It was interesting watching the crap come out, the water colour change from green, to brown, and finally clear.

    Here is the original pipe - looks to be in reasonable nick,yeah?

    And here is the hose sliced up:

    The inside of the hose has a combination of dirt, rust scale and broken down rubber from the inside of the hose.

    I installed new coolant - I realise that there will still be some water in the block, but I figure that the system is a hell of a lot cleaner than it was.

    I will take it for a 1 hour test drive, to cycle the coolant throughout the system. And then the car should be good to go for Corowa & Cooma.

    Cheers,
    GG.

    I had the same issue on my 85 110 with a 4bd1
    Hoses almost crackled when I squeezed them when they were empty. Solid rust and gunk about 0.5 mm thick
    I spent hours flushing block and pump, had the rad roded and serviced+ new hoses, all good now.
