    Bingo...
    Ok, sit back and be smug.
    At speed, the aircon is blowing bloody hot, yes?
    If the electric fan isn't pulling 100% air from the total face of the rad even under normal circumstances, it won't pull the additional bloody hot from the Aircon bloody hot and cool its own bloody hot as well in an efficient manner.!!
    Mine didn't rhyme.....
    Say it.. go on


    :oops:

    So how come the petrol kicks the aircon fans in for extra cooling?

    So does the diesel 1999 and on and it is all directed towards the viscous fan by the shroud.

    I might actually do that mod. When I am towing a full load the temperature does creep up on the big hills. I'll keep the viscous though!

    That mesh is a serious impediment to air flow, and that fan sucking will never cope.

    except that the viscous fails on a regular basis causing overheats.

    You have another problem, using just the airtcon fans in 36/38C aircon on flat out, the needle never budges past 12 o'clock on either of my P38's. Above 30/40 mph the fans only run from the aircon command as the ram airflow is sufficient to maintain engine temperature.

    All done. Refitted a shroud and nicley fitting to the fan.
    All refilled and sitting pretty.
    Air con on low to push a little harder, bonnet closed and sitting pretty at 12┬░clock!!( Well, just before)
    The fan now works half the time and definitely more effective.
    Road test tomorrow will reveal the results properly.
    No overheat problems Data, it never overheats!
    I did find a lot of dust in the lower part of the rad and half an hour of blowing air from the compressor has cleared a lot of crap.:cool:

    If you're out wading then give it a really good hose out afterwards. The mud gets in everywhere and turns to ceramic where hot.

    I thought Datatek's mod did away with the v/fan and the rad cowl.

    I have no business posting on this thread (other than owning a P38 4.6 Petrol) and wishing @Mark Piercy well in fixing his problem, but I have always believed that motor manufacturers have quite probably researched what is required for their product not to be constantly broken down at the side of the road and therefore parts are there for a very good reason. The actual quality of the parts (over time) may change as they seek to make more & more money by reducing costs but the basic designs are sound.
    I do shy away from all species of "Modification" (but not refurbishment for repair) because it puts you outside of the envelope of RAVE, LR Dealer Support and INDIE experience and you are on your own (other than some of the real Genii on this forum).

    His mod does, I didnt do this on mine, just fitted an electric fan.. the big mistake was not using a shroud. As wammers quite rightly pointed out, the fan was only cooling its own size in surface area and not the whole face of the rad!! Now I have a shroud fitted it is all singing and dancing again! Thanks to all your input and better understanding and helping.;):)

    The majority of cars these days use electric fans, quicker warm up when cold helps meet emissions regs.
