Pinto 1.6 Water Pump Fan Removal

[Guest Scotty]

I'm trying to fit a new water pump to my s6.it has a cortina 1.6L cortina pinto engine which I'm struggling to separate the fan from the pump I've removed the 4 bolts from the pulley but can't separate it for some reason any advise pls thanks Scott

I think youll find that the viscous fan is screwed onto the nose of the water pump with a left hand thread. Grip the pump impeller in a vice and tap the fan hub around clockwise to loosen it - the fan pulley should then just pull off the pump.

the hub of the fan screws onto the shaft of the water pump. You'll see a big hexagon for a thin spanner to locate onto.

 

This thread is a left hand thread so it turns the opposite way to normal threads to undo it.

 

Hold the water pump impellor in the vise (so the shaft cant spin) and get a thin spanner onto the fan nut.

 

PS....I never owned a thin enough spanner so I always ended up just using a flat blade screw driver and hammer to hit the nut loose.

I take two of the 13mm bolts out the pulley and this gives enough room for spanner, you not putting it back on are you mine is knackered and putting electric fan instead.

i've heard you'll gain up to ~5bhp not having the fan on there (and going electric which only turns on when needed) as its another thing the engine isn't turning around. could be rubbish but i would think it must make some difference not being there.

A fixed fan you won't be far off the mark but with a viscous fan there is not a lot to be gained as they also only come on when required. they just freewheel when engine cold.
