    I have done this to the radiator when hitting another water crossing on the main road at Cape York. I just didn't slow down enough and the water didn't seem that deep.

    When I stop and then drive in, even with water well over the bonnet this doesn't seem to be a problem.

    Much easier.
    That's a bloody good idea, Mike. Trick would be to remember to take it out afterwards...

    Could probably figure out some way of making the plate double up as a drop down table.

    One bloke I knew back when D2s were new made a wire hoop in a frame.

    Fitted it and left it there.

    If the fan moved it would skim on the hoop.

    I always used a tarp over the front,and didnt hit the water too fast,no issues.

    Did many water crossings at bonnet level.The only issue we ever had was the horns filling up with water,which caused a fuse to blow,and also stops the CC working.

    FWIW,the 100series LC was notorious for destroying radiators and the rad fan as well, after going through deep water,no matter what speed,and with a tarp over the front of the vehicle.

    There has been a further development to this saga. Having been around for a while I knew about the tarp trick, I also remember that Firestone SAT tyres in 750x16 size was the only modification done to ya landy plus a shovel of course. However I digress.

    So I suggested the tarp, remove the fan etc to my son however that is too much effort apparently. And of course it would involve having to stop and actually do something. So thanks to all the suggestions from his mates on fac**ook, he is now going electric fan from a falcon wired into a three way switch,temp sensor etc.

    If fact he has already purchased the falcon fan & shroud today from pick-a-part and has been mocking up attachment brackets this afternoon. No doubt I'll be asked to wire it up in due course!

    As Biggin mentions, the V8 and TD5 fans are different, anyone know why. And would the V8 one fit the TD5. I'm actually thinking of my TD5 in this case.

    cheers

    Fitting a thermo fan MAY work in NZ where it is relitivly cooler But here in Aus it would be a "retrograde" mod because the original fan setup is Far more efficient at keeping the D2 cool regardless of if it is a V8 or a td5.
    Then you have the possibility of the electric motor on the thrmo fan shorting out whilst is having a swim as well and then cooking the motor on the way home.

    If your young bloke wants to take his 4WD for a swim tell him how to go about it correctly and Not to take any notice of the tossers on facelick

    Okay - I’ll poke my head above the parapet and risk getting my head blown off Fan keeps eating radiatorsand say that I too are modding a Ford Falcon FG fan to see how it would fit my new radiator. And before the naysayers interject, I’ve gotta say FFS these fans keep a supercharged 5.0L V8 cool so why wouldn’t it work for a 2.5L turbo diesel. I am going to find out ….

    Onebob - FYI and consideration

    - Diesel burns significantly hotter than petrolFan keeps eating radiators
    - The radiator is a different thickness/profile on the V8 Ford
    - Coolant flow rates are different

    Just highlighting its not as simple as “it works on a bigger one”

    There is sooooo much info on fitting thermo's, especially with the EL falcon ones that are a marriage made in heaven with RRC rads, and RRC rads only.

    Just seems that a lot of people want to invent stuff, without even considering subtle things like flow restriction designed into a stock set up to suit a particular engine / rad / thermostat combo, etc. TDI's had this I think.

    Big fan and big rad does not necessarily equal 'cool'. The coolant actually has to stay in the rad long enough to transfer heat to the air via the rad, etc.
