Hey all

 

I have the electric fan kit from Zcentre and twice now I have parked up gone off for half an hour or so and then come back and the car wont turn over as there isnt enough juice in the battery. I have replaced my battery with a 680Amp job from Halfords and hopefully that will fix it but as its hot I'm guessing the fan just runs until the engine cools down but this could take a while???

 

Has anyone else done anything to fix this? Switch under the dash maybe?

that is possible, especially if your a jap spec which has a slightly smaller water pump wheel than a UK spec anyways.

Danny and other companies now do an overdrive wheel for the water pump to bring things back into corect sync, however am thinking thermostat or summitt, new or not the odd rare occassion has seen a faulty one from new.

good luck

While we are on the topic of waterpump pulleys.....An overdrive pulley and the Jap spec pulley are both smaller than a UK pulley.

 

Nissan designed the Jap spec water pump with its smaller pulley to spin faster than the UK spec...my guess is becuase the UK spec would be driven at a higher sustained speed...so the pump would spend more time spinning faster than a Jap spec so they had to underdrive it.

 

I'd be interested to know the size difference of an overdrive pulley compared to the Jap and UK spec pulleys.

if aux fan is coming on early when you look up in aempro you can see what degrees its been set to and you can adjust that easy, anothe point if the electric fan you have fitted is it spinning the right way round /?

hi mate thanks for the reply yes its spinning the right way. I've set it around 87 88 and it seems to be working just fine now
