Hi All,
Results Time!!
Well, only put 50-60 miles on with the new coolant, but I was impressed. Talk about a consistent, predictable cooling system. I wired a fan override switch while I was at it and hid it under the dash. I think I might make one tweak yet to the Evans Cooling system, and that would be the addition of a thermostat.
The Evans tech line said to remove the stat, but I'm running at 170 cruising. Granted it was not a hot day (77-78 ambient), but that was a bit cool. But considering where I'm coming from, that's nice.
When going back and forth between very hard driving and cruising, I'm used to a temp stair-step effect. Start at 170, drive hard, goes to 195. Comes down to 185, drive hard, goes to 200. Relax, goes to 195, drive hard goes to 215.
Yesterday, I was on again, off again, practiced some launches and even (way out in the country....) lit one up in second gear, holding it on the rev limiter for a good 6 seconds before the tires finally hooked (even dad was giddy and smiling after that one). Temp just kept creeping between 185 and 170, never going over 185.
Now when I'd stop, the temp would creep. And left to its own devices, it would get to 200 and the fans would kick on and I'd see a max of 210, fans cycling on and off. Nothing wrong w/ that.
BUT... the fan override does its job. I flogged the car hard then came right back to my driveway and kicked the fans on. Temp never went over 180. I shut the fans off when the needle started heading backwards, so I think they would've actually cooled it off more.
BOTTOM LINE: The Evans Coolant works. It doesn't cool better than water, but when the water gets HOT, it starts to lose its cooling ability. Evans does not. Go to the Evans website and read up on nucleate boiling to better understand. This stuff never gets out of control.
The "P.S." - After I bled the system, I went in to hook up the overflow line from the surge tank to the overflow bottle, no sooner had I leaned up against the fender than I saw a spray of liquid and then a plume of steam. My thermostat bypass hole plug had severed at the hands of the hose clamp and Evans NPG+ was shooting out like a fountain. Nothing I could do but watch it. $28/gallon, not happy. BUT... the aftermath was nothing big. 5 seconds with a hose and it was gone. The stuff is basically clear and non corrosive. And only a quart or two came out. Also non-toxic.
I approve!!!
