Several of the group were looking for a suitable pump for auxillary spray bar cooling
of coolent and/or oil recently..............Here is a cut and paste of the best of the lot during
testing of several.............Also the link to the complete study is below............
Nissan Terano (Headlight Washer Pump)
This is truly the big-banger of the group.
We’re told that this pump is part of the headlight washer system that was fitted to the Japanese-market Nissan Terano 4WD (aka Pathfinder). With a body measuring 140mm tall and 57mm diameter, the Terano headlight washer pump is one serious bit of gear – much bigger than the other pumps. The water inlet fitting is 8mm OD and the outlet is 5.5mm OD.
Connected to the Spraying Systems nozzle and operating at 14.2 volts, the Terano pump generates a massive 55 psi output pressure. And, as you can imagine, the water spray from the nozzle is beautifully atomised! Running at 55 psi, this pump has a water flow rate of 290ml per minute – so you’ll likely need a large capacity water reservoir.
Compared to the windscreen washer pumps, the Terrano headlight washer pump generates considerably more noise and vibration. As a result, this unit is factory equipped with rubber insulators on the mounting bracket to help reduce the amount of vibration transmitted to the vehicle body. Keep this in mind when you mount it in your car.
With such tremendous output, the Terano pump consumes a lot more power than its windscreen washing rivals. Peak current draw on start-up is 12.5 amps, while it draws 6.7 amps continuously.
It’s no wonder this unit has meaty power and earth wires!
