Manually Control Engine Fans

Q: Can the fans be rigged to come on while the engine is not running?

A: Yes. There is a temperature sensor on the block (passenger side under the third spark plug) with one wire going to it. Take the wire off and splice another wire off of it. Route that spliced wire into the car and up behind the dash. Then just hook it up to a switch. Run another wire from the other contact on the switch to a ground, and then when you switch it on, both fans will come on high.
