    Hot smell & sand driving

    Hey all.

    Just wanted some opinions on this..

    Recently took my Disco 2 (td5 auto) up Main Beach on Stradbroke Island. Dropped the tyre pressure to around 22 psi (on 18") and hit the beach. I'm running some BFG highway tyres so was expecting too need some extra surface area.

    Had no dramas and didn't get stuck anywhere.. did find it floundered about a lot in the looser patches. but that seemed par for the course.

    When we hit some fairly loose sand and decided to U-turn - I did notice there was a pretty hot smell coming from somewhere. Was a bit worried this might be the transmission - we were in high range at this stage.

    Any thoughts?

    Had also just had the 160k service.

    Cheers

    Wil

    Hi Wil

    Was it a brake hot smell ?

    If so could have been the Traction Control working hard.
    Cheers

    auto and the exhaust would be my bets.

    driving in the sand especially the loosish stuff is about the hardest thing you'll make a 4x4 do in terms of engine power output at low speeds. (read 20-40kph)

    The problem with these cars is they do it so easily and the driver is often unaware as to how much stress the actual drive train is under.

    Sand is like an anchor and the motor and tranny have to work extra hard.

    If a lot of sand driving is done or even on any auto box, fit an external oil cooler for the tranny if it does not already have one.
    Check the fluid if its cooked-it will smell burnt and get it changed.

    Also make sure the cooling system is totally up to scratch and a low water cooling alarm is fitted.

    Happy days

    Which is why I wondered why the OP was in high range. Selecting low range halves the work the motor and tranny have to do.

    Well.. not having done much sand driving I had consulted the manual.. which was a little 'vague' about low range. It didn't feel like i was losing significant amounts of traction, but I hadn't considered the extra drag / resistance effects of sand.

    On the return I opted for low range and all was betterer, and I just ignored the pace the other beach drivers were setting.

    I'm not sure how that would be possible.

    Edit, the auto will smell like hot oil when it gets hot.
