LOL really :D? Surely I can't be the first fool on here to actually fit one? You probably know more about 'em than me then - an I've been reading up on them for months to make sure my money was being well spent!

I'll make a note of that relay info, thanks that's really helpfun as we were having a hell of a time finding the right wires!

It has been well spent - believe me - brill bit of kit - yu only need the small one for a Hippoo. It should reduce Cavitation completely - that wot kills these injun (apart from coolant loss) - apart from the general **** design. Make sure you monitor the coolant temperature at the output from the injun - so yu get the hottest temp - not on the way back from the radiator, like LR :doh:
 
because it is well documented by peeps with a greater knowledge of thiis subject, than you or I.
It isn't THE big issue - it is ONE OF the - Hippoos are plagued with crap design features.

i thunk it were the hot coolant sat in the injun after switch off that caused probs

it is - the coolant contacts hotspots in the cooling passages and boils, thereby creating an insulating barrier of air which exacerbates the problem - that is called cavitation - similar to cavitation produced by impeller blades on pumps.
 
only interested i never seen any signs of it ,i have in other engines and water pump housings ,poor design with liners and gasket anddifferent expansion rates

On R118, the relay trigger wire is a Brown/Pink wire - the power wire to the fan is Brown/Red (unless its been wired with Trailer wire :p). You will need a diode if connecting to the N/K wire, or via relay if connecting to the N/R.

Unfortunately a late one with ac doesn't have a relay:( it has a control unit sat on the fan housing which receives a signal from the engine ECU which can apparently vary the fan speed! That took some tracking down as everything you read says there's a nice simple relay! Which is why I'm toying with separating the fans. Let the ECU do one normally and the ewp controller the other thru a new relay? Just depends on whether it throws a fit or if it buggers up the ac with only one fan? Only one way to find out!
Oh and another point! No ones said burn it yet?????

We must be making progress eh? I would probably have a better idea about what was going on with the wiring had I not been putting the lump back together :D. Seems like in this case seperation would be sensible - as long as the ECU doesn't throw a **** fit about one fan being isolated.
