Just a reminder to anyone who lives where it's hot. It's back above 100 and our merciful mild spring is over. Don't forget to check your coolant and hoses, your a/c, your belts, and your tires/tire pressure. Oh, and grab a Big Gulp for yourself!

One more thing. I put Royal Purple's Purple Ice in my radiator. I'll check in if it does any good. Anyone have any experience with this?

Hmm..I live in Houston so I know all about the heat. Please keep us posted on the Purple Ice, I may have to check that out myself. Do you mix that like coolant, or do you use it straight?

Yeah it is freakin' 106 f**king degrees here in Vegas already It was 82 here last tuesday...nothing like a good drastic temp change to screw with the body...

It's just a small bottle of additive. You just dump it in the overflow tank. Your chevy dealer or Napa should have it. It's about 12 bucks so I really hope it works. I haven't really driven with it in but I'll let you know if it runs cooler.

Yea...I hear ya. We don't get those 100+ days like you guys do in Vegas, but the humidity is killer here in Houston. 95 feels like 115.

I've never used the Royal Purple before, but tried Redline's version called "Water Wetter" which didn't make any difference temp-wise or that I could feel, just sort of made me feel better I guess... lol

Which reminds me, since I had the coolant flushed at 48K miles, I need to get some more... Might try the royal purple this time.

Let us know if you see any change!

I did some experimenting today and found that the Purple Ice did give some slight results. I drove around in about 100 degree temps and watched the temp guage (and the road, of course). I noticed that when the thermo opened, the engine did get a cooler gulp of water than before. About 8 degrees, or 1.25 tick marks. The guage would go up to where it usually does and every so often it would reduce quite a bit and then work it's way back up. I'd say that's pretty significant. I even drove on the freeway and in stop-and-go traffic. Same results. I guess I'll keep it. It may not sound like much but it will give a little more leeway when pulling my trailer during the summer. Oh, I'm ruling out any thermostat problems because it worked normally before and the truck is fairly new.

I would like to know about that purple stuff too. I have seen it for sale, but I have not tried it yet. We have hit temps a little over 100 a few days out here in CA. Just tells me it's gonna be a hot summer, and good thing I bought a boat!

az'03Silverado · May 28, 2005

I've been driving for a few days with the Purple Ice in the system and have had the same results. 6-8 degrees cooler temps. Just tells me that the stuff does what it says it will. It pretty much makes the radiator more effective. I had it on the freeway at about 65 for 10 miles today and it really worked well with the continuous air flow. I'm sold.

Does it really make a difference how "effective" the radiator is? I thought that as long as the engine stayed at the normal temp level, everything is ok. Engines are supposed to run AT certain temps for various reasons.

Good point. Normally it doesn't really matter and the truck has always run right on temp even during the hottest parts of the summer. But, when it reaches 115 here in Phoenix in a month or so, every little bit will help. Usually, when the outside temperature gets that hot, the fan clutch is almost always engaged. If this Purple Ice dicipates even just a little extra heat from the coolant, it will give some leeway especially when I tow my trailer around town.
