Installing an Electric Fan??
Alright so on my 84 z28 it has currently a stock thermal fan on it...today @ the junkyard i came across a fan off a thirdgen w/ what seemed to be the same engine as mine (lg4). Big question is how exactly do i wire this fan because all it has is a power and ground cable to it and will it be enough to cool my engine...?thanks!
PS, they want $35 @ the local junkyard for it..

If you can find them-although they require a little more work to fit..., if that stock fan won't cut it, there are much better fans such as the T bird or Taurus that are 2-speed and move a lot more air. Normally they draw a substantial amount of current but if needed I have a specialized harness made to deal with that by allowing 3 fan speeds. It can be used with and fan also or dual fan setups.

Re: Installing an Electric Fan??
Where can we buy a temp grounding switch online that I can thread in to my waterneck?
I was thinking 180 on and 160 off

Re: Installing an Electric Fan??
You'll have to go with Hypertech or similar if you want it to run that cold. 200 degrees is optimum for combustion efficiency. Carbon molecules break down better with a little heat and running an engine too cool will not allow enough of the fuel to atomize as well. A good rule of thumb is to remember that cold air is good and warm fuel is good-not the opposite...., its just one of the reason all the manufacturers run fuel lines through an area of coolant crossover lines on the intake wherever possible now. Warmer fuel breaks down easier and you can warm it even further if the fuel pressure is higher.

Found some switches, i'll stick with 190. It'll be mounted on the water neck so the engine should be running around 200 when it kicks in.
