Installing an electric fan and removing the stock supposedly adds power. I have an electric fan to install and my mechanic thinks it's not a good idea. He thinks the stock fan will keep the motor cooler and that if there is an electrical problem like a blown fuse, the electric fan may not work which may cause overheating. Does anyone have any information or advise for this? Thanks.

I got tired of replacing the fan clutch and installed a Mr. Gasket 14” Electric Fan with Painless Wiring and thermostat Kit on a 73 240z and it works like a charm, not only releases HP, also quiets the motor.

I too installed an electric fan, i am using a 12" unit, works well, have not had a problem yet. I also installed a override switch.

It's a great way to go,much quieter and it's the thermostat
that controls the temp of the motor. Install an overdrive switch
like Shaver and it will be fine.
I think they are more reliable because of fan clutch
failures. You may gain a few HP too.

my 240 used to stay above the halfway mark on the temp guage and i didnt like that.. with the elec fan i can adjust it to exactly where i want it.. and an override switch for traffic.. just dont forget about it when the cars running and you got your hand in there!

Hmmm. I have the stock setup on my '72, good friend runs electric on his breathed-on '78 280Z. He would affirm all the good things posted thus far, but I have one question... His car is nearly stripped, no accessories (radio, etc.) Mine, OTOH, has two power amps, CD changer, A/C, Maserati air horns, and Hella 500 driving lights. No problems with the alternator yet, either (over a year with this setup). I wonder if in a car as well equipped (some would say crammed with gizmos) as my '72, this wouldn;t be the straw which broke the camel's back. Suggestions?

there is a formula that you can use to figure out what each accessorie is pulling amp wise. it is


W=VI

W is the watt of the item in question (i.e. 150 watt amp)
V is the volts on the system and
I is the amps that the item draws

so I=W / V

in most cases you should know what the watts of your items.

by the way what is the ampage on a stock first generation z alternator?

Strictly Z has a high output alternator on there website that would solve all your problems. I think the 78 and newer Zs have a slightly higher output alternator than the older models, so that is a possability also.
