"Special" coolant
I've done a search but I can't find the post on that really expensive coolant that some people are using. If I reimber right it was about $50 to do a C4. It was to be used straight with no water added. Someone swore by it. Does anyone recall the name of it and and does anyone have any experience with it?? :chevy

Re: "Special" coolant (Skipzoom)
I think you're thinking about "Dexcool"...the orange stuff. And unless you have a 96-03, i wouldn't suggest it. It's great stuff...but will deteriorate the water pump seals in "older" vettes MUCH faster than the green stuff. THIS i learned from experiance! :eek:

No it wasn't Dexcool. More of a high performance type product.
I used one of these products in the '79 (at $29/16oz can) and was NOT impressed.

Re: "Special" coolant (Skipzoom)
I used to have a really bad temp. problem with my 91 L-98. As most of us know, the first thing to do Is to clean the road crap off the exterior of your radiator. I now fill my radiator ( In the summer only ) with 1 gallon of regular coolant, 2 botles of "water wetter" ( found In most speed shops ) and fill the rest with plain water. Sitting In traffic with the a/c on, my radiator temp stays around 170-180 :cool:

Re: "Special" coolant (BobMachus)
Yes, that is the stuff. $25 per gallon and you have to use a 7lb or no pressure cap, maybe a few more things too. Is it as good as they say? I road race my car in Florida at Sebring and by the end of a 40 minute session I am about 235 degrees. Too hot for me. I know that in the end I will probably end up buying a $500 aluminim radiator but this Evans seems like a possable alternative. Could someone tell us about there Evans experience pro or con. I am going to start another subject under Evan Coolant. Those with experience please respond here or there. :chevy :chevy :chevy

Re: "Special" coolant (Alchemist)
You are probably right but I'm looking at it like this, I've got a 160 degree thermostat in the car and a chip from TPIS that is programed for that temp. I can feel the car loosing power as the temp climbs higher and higher. What is it that all the tuners say, lower temps mean more power. I guess in a perfect world I would be driving around Sebring in August and be running 160 degrees all day long. Power is good. :chevy :chevy :chevy

Re: "Special" coolant (Skipzoom)
Just remember guys, after the thermostat is open, either a 160 or a 195, it's up to the radiator, coolant, airflow across the fins and the flow of the coolant (pump). The 160 will only start the flow sooner.

Re: "Special" coolant (Skipzoom)
Interesting article here:
http://www.caranddriver.com/article....rticle_id=2264
According to this, water is 50% more efficient at conducting heat than glycol.
Just changing your glycol/water ratio might cure your problems.
Good Luck, let us know how it turns out.

Re: "Special" coolant (FullShred)
That's a good piece of info. from the Zerex guy. As far as Evans is concerned I'm still waiting on their call. Their tech Dave was busy when I called Monday. Back to the Zerex guy, he says that you loose 25% of your heat transfering properties when you add coolant 50/50 to plain water. I guess the point is that with the right type of coolant in the radiator you could GAIN 25%. I think this is exactly what the Evans people are after. I'll keep you posted. :sleep: Waiting for Dave to call.
