Fan Switches

Nathan08 · Apr 4, 2011

I have two different trucks that are in question here. My truck has a LS 1 with the aluminum radiator in the back that I have a Taurus fan on controlled by the computer switch. The problem with mine is that every now and then I have to replace the relay that I mounted on the firewall that has gone bad. If anyone has ran into this can you give me a suggestion of what y'all have done to fix this problem? Oh and I do have a manual override on it for when I know we are going to be hard in it or heating up for any reason.

The other truck is a buddy of mines that we are fighting a problem of the elec. fan ( also off of a Taurus) keeps blowing 30 amp fusses. We are using a stock 90's model screw in sending unit that is in the block ( it is an iron block 350). Does anyone know of a better switch to use for his application we keep having issues of the switches going bad? Thanks guys

As we use only the high speed Taurus setting, there is a LOT of load on startup. The fan is designed to run on low, then switch to high. I run 80 amp maxi fuse. And a CONTINOUS run relay.

Here is the relay number:
BWD S605
