What do you use? Same as radiator coolant and if so do you mix with water or full strength? Thanks!

 

Same as the radiator. I used straight water and a bottle of Water Wetter with my JDM heat exchanger

 

The most effective water / coolant mix would be 80% water 20% coolant.

Use distilled water for less contamination.
Staight antifreeze will reduce you heat transfer.
You need the corrosion inhibitors that it includes. I think it also increases the boiling point. (not positive on that)

Straight distilled water would be optimum at the track then replace with the mix you drain out.

It is just over a gallon unless you have the oversize external radiator.

I have a question for anyone about how to hook up a light to monitor when the intercooler pump comes on. I would like to know that.

Can you just tapp into the hot lead to the pump and then to the light and then ground? Or will that bleed off voltage and harm the pump motor?

Thanks

 

Is this the right mixture for Hot Florida? I don't want to blow my truck up...

 

Im pretty shure the pump runs of the neg signal from the computer.

 

80% dis water, 20% 40 below, 1 can water pump lub.

 

If you use a LED instead of a light, the current draw will be so minimal it won't affect anything.

Put a 1200 Ohm resistor is series with a "standard" LED and your current draw is only 10 milli-amps. If that is too dim, just use a lower value resistor. If you don't use a resistor, you'll burn the LED out.

 

Ok, makes sense. Where would be the best place to make the tap? Light on when intercooler pump is working.
Thanks

It'll give you an idea of how to wire up the pump, as well as where to wre in the LED.

I plan on hooking the LED up to the pump hot, so when the pump is on, the LED is on, no matter if I'm running the pump, or it's running due to normal operating conditions.

 

I use maple syrup. It works great.

 

I think the 80/20 mixture is right George... I changed mine out not that long ago with Steve when we cleaned the intercooler. Distilled water is better, but not crucial by any means.

I think we just filled 4/5ths of the tank with water, then we added the coolant..... you will need to fire the truck up and let it run for a bit...then fill it to the line with more coolant.

Maybe Steve will grace us with his presence and confirm this...
