Electric fan install help!!

[sd0676]

Hello, First let me say thanks for any help. I am installing an electric fan from a 94 into my 91. I've done the alt. upgrade. What size fuse do I need going to the 100 amp relay that runs the fan from the battery??

Dont know what a 94 fan pulls at startup thats what you have to figure out. Once you get that just go a little bigger on the fuse.

The fuse for the stock 94-95 GT cooling fan (it's two speeds, the V6 fan is one speed) is 60 amps IIRC. NOTE: When these fan motors melt down, the fuse seldom seems to blow. Some fans were even retrofitted with a circuit breaker on the high speed terminal for the event of an internal short.

Choose your circuit protection carefully.

Good luck.

Good question. I see everyone saying use a fuse/circuit breaker but they rarely mention a specific size to use.

How about the 3.8L Taurus fans, what size is reccomended with those?

Is a circuit breaker any faster or more consistent to react than a fuse? How do you reset the small 12V circuit breakers, by removing current to it (by turning the ignition or fan switch off)?

I'm installing my Taurus fan with a soft-start controller that doesn't require a relay but I'm still a little confused what kind of circuit protection to use. I don't believe the instructions specify what amp rating is needed. I believe the controller is rated for 30-35 amps, so I figured I'd go with a 30 amp fuse (or circuit breaker)? Any comments?

Fusible links are more common because they're cheaper. Some newer cars do use ANL style fuses however.

The DC Controller comes with its own fusible link.

your going to need about a 40 amp fuse for the taurus fan...it runs a little over 30 at high speed so a 40 should be fine...

Bosch 75a relay, $2 fuseable link, $2 switch and 10G wire is what I use with my sn95 fan. Been flawless for over 5 years now

The start-up draw will probably blow the fuse.

Yea, I went with a 75 amp fuse just because of the initial start up.
