Evans Coolant
 

Has anyone tried this coolant in their car?

Re: Evans Coolant
 

nothing better than straight water

Re: Evans Coolant
 

I used it for several years when I had a set of heads that would leak when coolant pressure got over 10 -12 PSI .
Evans coolant allows the use of zero pressure in the system so I got by for a year or so till I replaced the heads .
I also used it in my Stocker ,where I found it really helped the consistency and a little quicker ET even though the coolant temp was higher .
Your coolant temp will be higher due to the coolant having a better heat absorption than straight water, meaning the actual temperature of the cylinder and head are lower because the coolant is absorbing the heat.
The coolant is defiantly not for everyone ,but it does have it's uses. especially for racers who have to store their cars in cold areas and it does not damage aluminum heads or radiators .
It's also a little pricey , but it can be reused over and over . .. there is very little degradation.

Read their web site ,It really explains the function of the coolant
I noticed you are in DIV 5 , it might have some benefit over straight water at the higher altitude tracks due to its much higher boiling point.

Re: Evans Coolant
 

No "coolant" cools, they all raise operating temp, holds heat and requires a longer time period to get that temp down to pre race temp. If that's attractive to you, go for it.

Re: Evans Coolant
 

The Evans stuff needs a high flow system to work properly. While it will absorb the heat better than water, if your system cannot quickly move the Evans, the car will run warmer rendering the coolant useless at this point.

If you're running any OEM components (pump, radiator, etc.), the Evans is probably not for you. In an application where you have a big electric water pump, small aluminum rad with large rows, etc., you may find a use for the Evans. That being said, in a high flow cooling system, with good components, you shouldn't even see the boiling point of water unless you're heat soaking the engine. Personally, I wouldn't consider it for my vehicles unless I lived in a cold environment.

I put it in my car two or so weeks ago, due to the fact that water will freeze here in NJ and I will be going down to Florida for the Gators, Ill post back in a couple of weeks if I see any differences.

Re: Evans Coolant
 

Thanks for the info. Once car gets hot have a hard time getting the car to cool down after a run in short amount of time. It gains temp quick after making the first hit of the day.

Re: Evans Coolant
 

straight water is your friend. What temp are you staging at and what do you have for a cooling system?

Re: Evans Coolant
 

The condition you're describing can usually be attested to an inadequate radiator, and/or fan set-up. I'm leaning more towards the radiator.

Re: Evans Coolant
 

agreed

Re: Evans Coolant
 

Evans will not make your vehicle run cooler, its just a legal fluid that won't freeze, rust and has a higher boiling point.

Re: Evans Coolant
 

Car has a Afco scirocco radiator/fan/shroud and a Meziere 55 gpm pump with 16 an hoses top and bottom. Had a 12 an hose from top of intake to top radiator and switched to 16 an and it did help with cooling the motor down a little faster but still can’t cool down very quick.

Re: Evans Coolant
 

1. that water pump needs a radiator with the same size inlet and outlet as on the pump.

2. what temp are you staging at?

Re: Evans Coolant
 

The larger AN helped because the pump was able to push more coolant through the radiator. The more coolant you can push through the radiator, the faster it will cool. At the same time though, you're trying to push 55 gallons of fluid per minute through a 1" (16 AN) hole. You really need to open up the inlet/outlet to get more coolant through the system. You could put a stock water pump on, and see no change in temperature, with the restriction being caused by the 16 AN inlet/outlet...

I understand you may be space confined with your application, but I would see if I can get something larger than a 2'x1' Scirocco rad. I honestly didn't even know those things were still being used outside of dragsters and altereds.

Re: Evans Coolant
 

I try to roll into the water at 110 and leave the line at 140 and go through the lights at 170 +. Car does have double pass radiator. Talked to Meziere they told me to use the 12 an on top and 16 an to slow the water flow down. Both Afco and Meziere said this should have no problem cooling off after a pass.

Re: Evans Coolant
 

what's in the radiator now?

Re: Evans Coolant
 

Water and Purple ice

Re: Evans Coolant
 

get the purple ice out

Re: Evans Coolant
 

Why?

Re: Evans Coolant
 

it's a coolant, coolants don't cool and it also has a reputation for eroding aluminum.

Re: Evans Coolant
 

I agree with slowing the flow down and let the radiator do its job, which is to radiate the heat out.

Re: Evans Coolant
 

Could you elaborate? This does not seem to be most folks I know experience with products like this. Is Purple Ice different from other "water wetter" type products?
Thanks.

Re: Evans Coolant
 

water wetter, purple ice and the like are snake oil. I've tried them many times since Redline's water wetter was first introduce to the market in the late 70s! They do nothing to reduce water temperature and today with real time data acquisition systems, it is easy to see and the results indisputable.

Re: Evans Coolant
 

Finally got out in the shop my radiator measurements are 23 x 3. With the 12 an upper hose it actually held more heat in the engine. I know there are a lot of cars with the same setup and don’t have this problem. I’looked at the VP web site and they have a coolant called stay frosty.

Re: Evans Coolant
 

coolants don't cool
