Adding an Electric Radiator Fan to a 1992 Super Custom

Hi Everyone,
Has anyone tried to add an electric cooling fan to a Hiace Super custom?
I have just had the head replaced and want additional cooling for the summer months - especially when towing.
Cheers

My SC is on stands and stripped own for bottom half repaint plus new sill on one side. looking in the front there are 2 radiators one vertical with usual viscous fan and separate AT oil cooler plus one horizontal with AC condenser with a massive electric fan on top, talk about comprehensive cooling and I can still get 110 deg C when towing up hills.

But isn't part of the problem that the one underneath with the electric fan serves only the aircon (am I right) and that leaves only the one with the engine-driven fan to cool the engine. When we had our Hiace I'd thought about fitting an electric fan but I don't think there's really enough room, and the alternator was too small to support that additional electrical load. This was discussed a little in another thread a while back.

The horizontal rad is connected in series with the vertical one the condenser below it fan on top JP parts show the two rads but not the fan condenser set up all on one page.

@JT69 my bad, I need to temper my comment with the suggestion that it may vary with the many different variations of the Hiace. Since we sold it I don't have it now to go and look, but we had to have the vertical radiator replaced in ours when it rusted out and began leaking, I'm almost certain there was no connection between the engine cooling system and the horizontal radiator, the horiz one seemed to be only for the elaborate dual aircon system. But then that van was weird in quite a few ways and had certainly seen its share of modifications.
The Dyna we now have shares many similarities with the Hiace but it has only the one (vertical) radiator.

I know someone here who mounted a horizontally-oriented auxiliary radiator about halfway between the front/rear axles as there was some open space, and put a switched electric fan on it. They can flip it on during hill climbs etc, for added cooling ability.

When I was messing about with sensors on my engine, I discovered the horizontal electric fan is also triggered by a temperature sensor near the head coolant outlet (top/front of engine).

Disconnect that sensor and the fan whirrs into life!

For the Original Poster: Your coolant could perhaps be changed for new Toyota long or extra long life, and also people of the Hilux group sometimes add oil to the main fan boss. No electric fan will rival the power of that engine driven fan (in practice), just make sure the radiator flows well, is clean, and the fan boss transmits the power when it needs to.

Also fit a decent gauge (or modify the original one to remove the dead spot) so you know when to slow down on a journey, to keep engine temperatures under control. The coolant system being tucked under the van like it is means the airflow isn't as good as on a truck, so the fan is essential at all times.
