The last one.. If it robs power.. why did they design our cars to run coolant through the throttle body?

By design, the coolant lines are there to prevent the throttle plate from freezing under cold temperature. Because of this, the throttle body receives the same coolant temp running through the engine, which also heats up the intake temp.

I had my accord bypassed been thinking about it on the solara but never done it. Altough I have thought about relocating the IAT to the bumper or some similar place.

Straight water cools better than coolant any day of the week,


ouch ... is that a joke? Makes you question the rest of this guy's advice.

yeah, water is an excellent heat sink, but adding ethylene glycol makes it a better heat sink. Remember colligative properties from 7th grade science class? Any solute dissolved in water will increase its boiling point and decrease its freezing point, hence coolant/antifreeze.

Straight water does "cool" better than coolant (Antifreeze+water).

Being a good coolant does not mean being a better heatsink. Coolant is made to hold on to heat and move it to another location. Heatsinks are made to dissappate heat quickly, which is the exact opposite. What you want in a cooling system is a high specific heat liquid to hold onto heat and move it away from the hot parts, then run through a radiator (with a low specific heat, like copper), which then acts as the heatsink and dissapates the heat into the air. If the liquid in a coolant system has a low specific heat, it cannot hold onto the heat long enough to move it away from the engine block and into the radiator.

Adding antifreeze lowers the specific heat of water, which makes it let go of heat better, and makes it not as good for moving heat away from the engine. Antifreeze has about half the specific heat of water.

Antifreeze is used for two main reasons, first is to lubricate the coolant system, second is to make sure water always stays in liquid form no matter the temperature. If Antifreeze was a better heat mover, there would be no reason to use water at all and engines would be built to use pure antifreeze. However, it does not remove heat fast enough, so engines are built to take a compromised 50/50 mix.

Did the TB coolant bypass a while back. The metal on the TB doesn't get as hot as it used to. You're not gonna feel any increase in power from this alone, thats for sure. I wouldnt recommend it if you live in a cold climate - dont want that butterfly valve sticking.

I am glad you remeber your stuffs from grade school, but this also means you need to go take class in college.

Because water have hydrogen bonding ability with the oxygen atom, this will induce higher boiling point because more bone strength. The ethylene C=C an unsaturate organic compound however will lower the freezing point. Therefor it is called ANTIFREEZE.

So a radiator with full water vs full antifreeze, the one with full water will win

^^ Hey Turbo, my quote questions the author of that accord article, not your post, did it sound like i was attacking you? :o apologies if that was the case.

in any case, that accord guy has several questionable points, like the others have posted about the TB valve etc, and my quote about the coolant is just one of them.

but it seems like you just paraphrased what I said, that ethylene glycol acts both as an anti-boil and an anti-freeze, but neither of us distinguished the difference between heatsink, heatmover, heatdissipator, specificheat, etc,.

Jon11582's excellent distinctions puts the coolant discussion to rest. :D

who has actually tried this stuff anyway
remember a while back the DIY with the butterfly valve? There was mixed results on that one and this one may have more of the same
so before i go tinkering away i wanna know what other people have noticed.
