Features

• 180ºF preset turn-on temperature

• Includes heavy duty 40/60 amp relay harness
• AC override circuit included

Part Number: DER-16738

• Application: This kit suits activating up to 2 electric fans with a combined draw of 25 amps, using a push-in radiator fin probe rather than a capillary tube or NPT threaded sensor, making install simpler on radiators without a suitable boss.

• Size/Spec Context: The 25 amp rating gives more headroom than the 30 amp and 40 amp harness kits elsewhere in the range are designed around, suiting dual fan setups where combined draw needs to stay at or under 25 amps rather than running two separate relay kits.

• Construction Note: Includes a push-in radiator fin probe, heavy duty 40/60 amp relay harness, relay wire harness and electrical connector for a complete DIY install, plus an A/C override circuit so the fan can be triggered independently when the air conditioning compressor is engaged.

• Fitment Note: Suits radiators with fins the push-in probe can be inserted into. Confirm your combined fan draw stays at or under 25 amps before wiring two fans through this single controller.

• What to Pair With: Commonly paired with dual electric fans wired together where combined draw fits the 25 amp rating, or a single higher draw fan with A/C override wired in.

• Practical Buyer Tip: The included A/C override circuit is worth wiring in on any vehicle running air conditioning, as it triggers the fan when the compressor kicks in regardless of coolant temperature, preventing high side pressure build-up at idle.
