My feeling is the full time fan cools the truck down far to much. In 95* and below you can almost drive with no load and never overheat. This is why I moved to an electric fan. Once you hear up your stink goes away and stays away until you shit down again.

I agree with TD the best thing I have noticed is getting the engine up to temp. I have the front of my rad totally blocked and its still hard to get these to run hot which really cleans up the exhaust. I am ready to try the mechanical fan delete.

Friend of mine told me when its -15C, just pop the fan belt off (easy on the SBU's), makes a world of difference in both smoke, and you actually get heat in the cab!

So I seriously thought this thread may have finished (with good valve seal replacement info) but now came back with good engine heat info that is very much worth while!

I like mechanically driven ...anything... but may have to see what I can do about a little more engine heat. Great posts folks!

My 406: XM-47's, hydraulic driven Garwood 10,000lb pin-on front winch, custom bumper, small jib for front or rear, PTO driven 20,000lb Garwood rear winch w/ level wind, (super secret) forward-N-reversing unit for rear winch/PTO operation, 8 speed 2x4 conversion...+2, front 3pt hitch, HT11-A1 backhoe.

The old mac trucks (and others) had mechanical shutters that closed over the radiator until they heated up. Looked kick-@$$ and zombie proof when closed...fully mechanical...

Very nice! ...appreciate the emphasis on 'mechanical' too. One of the tricks on the old M715's I worked on was a Ford Taurus 2 speed fan install. THEY MOVE AIR, like WOW. Wonder if I can find a 24V version since my Mog supports the 24V system. ...I'm a tough sell on electic though...

Search is your friend. Fair amount of info on electric fans and Mogs here. The low speed powered by 24v's on the Taurus and similar fans works well so far.

This is the Australian electric fan and electric water pump fitted to the 352 but remember the engine smokes when cold on start up and is clean when the engine is hot.
