coolskaterkid Posted October 6, 2009 Share Posted October 6, 2009 so my 84 gl ea81 orignally just had one fan, i found the other one at the junk yard. I dont have ac so i plugged it in on the driver side where the plug is. But when it gets to temp just the one fan kicks on. I tested the fan by jumping it and it works just doesnt kick on. Is there any other reason is it because mine doesnt have ac or somthing? Link to comment Share on other sites More sharing options...
GeneralDisorder Posted October 6, 2009 Share Posted October 6, 2009 You don't have the AC relay's to power the fan. You can wire in a relay from the fan thermo-switch in the radiator. Just wire the relay to trip off the ground signal from the thermo-switch and power the second fan from a fused lead off the battery or the main junction (fusible links).

GeneralDisorder Posted October 6, 2009 Share Posted October 6, 2009 You don't need the second fan - a good radiator and the single stock fan will do the job just fine. You are just sucking more juice from the already taxed alternator - they only have 50 amps at full speed and at idle it's about 15 or 20 amps - which is generally when you need the fans (car not moving, idleing).
