I've done the reading, and I want to purchase a new fan switch.

I have a 87 Z28 with the LG4, non-CC. So I don't need to worry about how low I go since my carb will squirt the same fuel regardless right?

With that in mind, what's the lowest fan switch I can get (And it's turn on/off temp's)? I don't want to spend $50-60 on an adjustable one, I'm hoping for a stock replacement.

Also - if you have the part numbers that would be helpful.

 

If you anticipate ambient temperatures below 10°C, you might want to keep the coolant temperature above 80°. Much lower than that, and you won't get acceptable fuel evaporation in the intake, and may actually get carburetor icing in humid conditions and colder air. If you only use the car in the summer, and don't need to worry about temperaures below 10°, you can probably go as low as 75° without noticing any problems.

 

I thought pretty much the lowest fan switch I could get is a 160 from Hypertech? Is there a GM one that low?

<And yes, the car is summer only>

 

Not that I'm aware of, but I don't know everything. I do know that AutoMeter offers a wide range of temperature switches for about $20 each.
