    Silicone Coolant Hose in Blue Suitable for Discovery 2 2.5L TD5 Vehicles (Includes:Full coolant Kit) (7 hose kit) - BA 10760 - BEARMACH Branded - Bearmach
    I haven't had any leaks yet with my Samco and Pioneer hoses, but I've only been running the Cummins coolant for abour 8 months

    The genuine top hose leaked like a sieve with genuine (Caltex) OAT.


    That Bearmach house is UK made so hopefully ok.

    Rick, are you using PG Platinum?
    Dave.

    I was asked " Is it ignorance or apathy?" I replied "I don't know and I don't care."

    Thumbs down Buy quality or....

    I agree with Tombie re Samco..

    Have purchased the oil cooler blanking plugs from Racebikebitzuk(via ebay)

    $30 freight from UK, hence I bought 2 with quality clamps for $54. Part No. BCP/19-RED.

    DO NOT BUY blanking plugs from Supacr@p..3mm thick on the sides, 1mm on the end! Built to fail...

    And don't ask how I know..

    Cheers

    OEM hoses

    I remember MANY years ago, travelling with an RAA service mechanic to collect an HK Holden with a blown water hose. It was 13 months old.
    But then, I have had 13 year old cars with original hoses.

    I had an old Patrol that had it's own version of the secret hose hiding under the water pump. I touched at at about the 25 year mark and it cracked like Land Rover interior plastic lol.

    Silicon

    The issue of quality of silicone as with any product is still suck it and see...

    PG Platinum is by far the best option, I've been using it for 8 years in the D2 and the last 4 years on the RRC as its also suitable where non OAT is specified.

    Previously used Cat ELC for a couple of years in the D2 but the PG tech wise stacks up far better.

    Having changed the top hose last night and having to retrieve the bleed bung that fell away from the hose, pulled off the 10 year old water outlet and other than the normal diecast darkening from the coolant doing its job, the inside of the head was a beautiful clean shiny light bronze tint and absolute zero corrosion anywhere inside it or the water outlet.

    I just fitted the Bearmach upgrade top hose which has the thermoplastic tees in it, I still can't justify the cost of silicone over the known issues with it.
