was intsalling my 5/16" motordyne and it came with a coolant control valve.....dont know what it is, and if I need to install it...any ideas?

 

You don't have to install it, but its definitly better if you do. It will allow your plenum to run much cooler.

And since you live in SD, you can turn the valve to the off position and just leave it there all year round.

 

just installed it but wondering why would cutting off the coolant to the engine beneficial to the motor?

 

Its not coolant to the motor, its very hot coolant comming out of the motor that is being flowed through the plenum.

This is done to heat the plenum in the event of driving in really cold weather. This is to prevent ice formation on the throttle body butterfly valve.

Problem is, they heat the whole plenum in the process all year round. Even when it isn't needed.

The CCV allows you to not heat the plenum when the extra heat isn't needed. If you aren't driving in cold weather, you don't need your plenum to be heated.

 

I think i just might install mine now. I also had no clue how it actually worked.

 

Tony, are you not putting directions in your kits???

 

kit comes with directions and they are also on his website

 

Directions always go into the kits. They are a required part of the kit just as much as the actual product.

Other than the tools to put it in, the objective is to make each kit with everything needed for a complete installation.

 

Oh I Know this...I was just r***ing you.

 

tony-
i have the basic 5/16. i think the CCV is pretty cool idea, but i don't have one. can u just sell it to me seperately?

 

Could you guys tell me why ice would form on the butterfly?

I know it says that the ccv is used for climates usually above 45 degrees, but where would the water / condensation come from, and how would it freeze @ underhood temps??

-thanks

 

Ever heard of google or yahoo? Just put in "throttle plate icing" and you will have a few thousand hits... magic!

 

wow undrgrnd...thanks for the new sites i can check out. btw blow me

the sarcasm on this site is ridicolous.

my question was more at what temps the butterfly would freeze, but i guess i'll spend some time searching.

 

haha

 

You could install just a CCV, but you really want it with the Aramid gasket too. (You can find the Iso Thermal upgrade kit on our website.)

You need both the CCV and the Aramid gasket to really make a difference on the plenum temperature. There are 2 major heat inputs to the plenum.
1) Hot manifold heat transfer.
2) Hot engine coolant heat transfer.

The Aramid gasket cuts off the heat soak through the lower manifold.
The CCV cuts of the heat transfer from the hot engine coolant.

Think of it this way. The aluminum plenum assembly has the equivalent of two blow torches pumping heat into it. If you block the heat from one torch, the plenum will still be quite hot. But if you block the heat from both, it will make a big difference in assembly temperature.

This is why you need both the gasket and CCV for a real effect.

 

I use 45'F as the minimum temperature to turn on the CCV because it leaves a good (safe) margin above freezing.

 

thanks hydrazine... once the engine is warm, is it OK to close the valve again?

 

Valve position is adjusted based on atmospheric conditions.
Not engine temperature.

If it's freezing cold outside, turn the valve to the "open" position regardless of engine temperature.

OTOH, if you have the Copper Iso Thermal, you don't have to adjust anything. Its all automatic and it works even better than the CCV if you are driving in cold weather. The Copper allows you to heat the throttle body without having to heat the entire plenum. And this means you can take better advantage of the very cold air you are driving around in.

Cold air is great for the engine, just not the throttle body butterfly valve...

 

i was speaking of the manual valve style

 

thanks for the quick replies...you answered my question and i'll be ordering soon.
