m22x1.5 to m10 adaptor?
franky - 22/9/09 at 04:08 PM

My radiator fan switch hole is a m22x1.5... my temp gauge runs off a m10x1 thread. I'm going to use the temp gauge to run the fans as it has the ability to do so, however I can't find any adaptors anywhere? can't even find a m22.1.5 bung that I could drill and tap.

anyone have any ideas of where I could find one?

Your temperature gauge sensor should be located in the thermostat housing rather than the radiator.

If the fan switch is already located in the thermostat housing, would be it possible to make an adapter out of an old fan switch? Failing that it shouldn't cost much to get something suitable machined.

Yep, as mike says your temp gauge needs to be in the head/block, not the rad.

Even ones that fit in the top hose dont really give you an idea until the thermostat has opened up.

Doesnt the ZX12 have a temp sender in the block?

I see what you mean.... use the temp hole in the block, back of the cylinders as the main temp take-off.

however why are there temps sensors/switch's in the rad on the zx12 then?

Also might be best to leave your fan switch controlling the fan.

The ideal postion for a fan switch is about halfway up one of the radiator end tanks, the fan switch is there to control radiator temperature so that water in the correct temperature range is available to the engine.

I've got a polo radiator fitted so I can't use the original switch. The fan will be controlled by a radiator switch still. I was going to use the temp gauge I've got as that has a switchable output that I can set to match the operation of the original fan switch.

I'm just not sure how accurate the reading of the radiator will be in relation to the actual temp. Think I may use it.

The switch in the rad is for the fan only, Not a temp sender for the temp gauge.

The hysteresis of a fan switch is quite large so it doesnt matter if the temp it sees is a little skewed, and it need to know the temp of the water in the rad to determine if there is enough airflow through the rad to give you enough cooling.

The temp gauge needs to show the temp of the water in the engine, as this is where it is most important for you to know. The temp reading in the rad will be a good few deg lower than this.
