electric cooling fans
Thinking of replacing my current junkyard Dodge dual cooling fans with a new set. I would like to get some that draw less amps than my current ones. Not sure what mine draw but when they turn on it drops the amp gauge below 11. Anyone using a set that bolts right in and are happy with them? would like a one piece 2-unit bolt in. Again got these out of a junkyard 5 years ago and the alt. works fine while running everything else until they come on. During the day all good at night when it drops. Had alt checked it is 110 amps. all good.
Thanks Can someone move this to electrical. Thanks Last edited by kglowacky; Yesterday at 07:39 PM. |

My truck had a 78 amp alternator when a previous owner converted to internal regulator. I installed dual fans and the 78 amp alternator would just barely keep up.. At night with lights and AC running, it simply wasn't enough alternator.. I switched to a 100 amp alternator, 8 gauge charging wire to the battery and problem solved.. |

Re: electric cooling fans
I have a 110 alt. I have a LS 1 swap. The new gauge wire is 10 on the fans to a separate relay for each fan. I am thinking the old Dodge fans are drawing more then 40 based on the fact the original wire looks like 8 or 10. ( I spiced in before the original plug of the fan unit.) Looking at some new replacement fans the wire size appears to be 12 or 14. or I will need to upgrade my alt to 120/130. trying to avoid this.
