THERMATIC® FAN SWITCH (Mechanical) (Part #0401)
The Mechanical Thermatic® Fan Switch can be used with our Thermatic® Electric Fans & EWPs®. It senses the coolant temperature after it passes through the engine block prior to entering the radiator and is adjustable from 40° to 100°C (104° to 212°F). The Thermal Switch is mounted near the radiator and the stainless steel probe fitted inside the radiator hose. The Thermal Switch & relay kit enables a fan to operate both thermally and also when the air conditioning is running.
Sensor Wire Length: 110cm

OPTIONAL ACCESSORIES
Should you not want to squeeze the probe of the Mechanical Thermatic® Switch between the radiator inlet and radiator hose, or the radiator fins, we recommend you look at part number 0409 or 0400 (Sold Separately).
The #0409 is a simple, economical Adaptor Kit allows easy fitting directly into the top radiator hose. Just fit the probe into the compression fitting, remove about 17mm (2/3”) of radiator hose, fit the adaptor between each hose and secure the hose clamps. The kit comes complete, as shown, for a watertight and effective probe installation. Extra rubber sleeves are supplied to enable fitment to radiator hose sizes from 32mm to 40mm (1¼” to 1½”) diameter. Suits all temperature sensors with either a 5mm (3/16”) or a 6mm (1/4” outside diameter and temperature gauge senders with 6mm (1/4”) NPT thread.
Note: This is an accessory for use with #0401, #0404, #0444 and #0500 Thermatic® Electric Switches.
Should you need to account for Air Conditioning, we recommend the Mechanical Thermatic® Switch(12V & 24V) plus Relay for Air Conditioning, Part #0404.
