Viscous Fan Issue

<< < (4/4)

L90OOK:
I have run an electric HD Kenlowe fan for years with mixed results!  :roll:
The standard Thermostate & relay setup is useless.  The temp senders are taken from the top hose which means the fan only switches on when the water entering the engine rquires cooling, i.e. to hot to be of any cooling use to the engine!  :shock:  :?
Also I foung the termostatic controller, that switches the fan on/off, lasts a limited amount of time before it gives up all together!  Also the standard setup doesn't give you the ability to override the thermostatic controller & switch the fan on when you want too.
I have now fitted the X-Eng solution which is suberb.  It fits into the bottom hose where the water is going back into the radiator from the engine.  So when the water coming out the engine is too hot it switches the fan on, thus providing forced air cooling from the first instance it is required & switching the fan off as soon as it's no longer required.  The X-Eng solution also gives you the ability to wire in an override switch to switch the fan on at your discretion.
I have run this setup for a while now...whilst towing trailers upto 3Tonne & it has performed flawlessly.  
This is on my 110 200Tdi CSW, uprated I/C & tweaked fuel pump.
Hope this helps :shock:  :roll:
