cooling fans

[grandpxigtx]

hey fella's just i want my cooling fans to come on at a lower temp. instead of the 225 degree that's stock so is there any trick out there i can do?

Buy an adjustable or lower temp electric fan relay from a local performance shop. The one on my S-15 is non adjustable and kicks in at 180 and cost under 25 bucks cdn

cooling fans

okay i have a 95 grandprix with a 3100v6 two cooling fans i bought a temp.remote fan switch that sticks a probe in the rad. to turn the fan on at 180 degrees but it dont work or i hook it up wrong cause i put a fuse (10 amp) between the relay and the battery and its blowing yht fuse.

Stock cooling fans are turned on via the GND, not the power. The ECM applies the GND signal to complete the circuit. So to add an alternate switch, you need to hook it up similarly, but triggering the GND, not the power.

I had a similar problem with the fuse, I just added thicker wires to the relay and added a bigger fuse and it works fine. I just used a ford taurus fan from a wrecker $5 but I have found that a chrysler fan draws less power

Temp Sensor

Is there any electric fan that has a sensor that screws into the head/block instead of the phony probe that pokes into the radiator? '86 S10 3.1.

Edit: Derale http://www.derale.com/electric-fan.html I wonder if you could use this sensor and relay with a different fan such as the flexalite Black Magic. Because of the flexalite's built specfic for the S10.

Since that is just a relay setup, it should work with any fan.

Do you know what kind of p/u the "Black Magic" has? I read their site and they mention an adjustable relay but they don't say anything about the sensor type.
