Making the truck run cooler (cheaply)

[pauly383]

Sure , I can verify when I get home tonight . Saved the box .

This is what the guy at the Napa by my work told me just now on the phone TS6641 .

Just looked online and it says its for gauges , but i will still check when I get home .

And FYI , same thing happened to me the first time , got one for idiot light .
The difference is the idiot light one has a short fat probe , and gauges have a longer skinny probe

I would not run less than a 50/50 mix of water/antifreeze.

Air pockets in the cooling system will allow the coolant to expand and raise the operating temp.

DEI makes a additive that will lower operating temps as well.

Straight water cools MUCH more effectively than any coolant/water mix. The Thermal conductivity of water goes down with the addition of nearly anything else. There are two reasons for using something besides straight water in the cooling system. Freezing point and anti-corrosion. Something tells me that Davis doesn't get all that cold, even in the winter. Right about now you've got MiniSkirt Weather (tm) so freezing isn't a likely problem.
You can run straight water with a corrosion inhibitor for the summer. Come fall I'd add some coolant.

Check out Redline's "WaterWetter" A problem that straight water does have is that it has too much surface tension. That's the property that allows you to slightly overfill a glass. In a cooling application that property doesn't always allow the water to get into all of the nooks and crannies of the cooling system (air bubbles). Air acts as an insulator which overheats the metal behind it. The overheated metal then superheats the nearby coolant making steam. That steam puts a huge load on the radiator. Products like WaterWetter and the DEI clone/copy actually reduce the surface tension of water so that those air bubbles can't form in the first place.

Here on the coast we can run straight water with some anti-corrosion addititive, though I usually don't as I want to be able to go into the mtns w/o worrying about the coolant freezing.
BTW, only fill with De-ionized or Distilled water. You don't want the minerals in your local water in your cooling system. They reduce the water's cooling ability and eventually make a mess out of the system.

Redline Water Wetter.
This stuff WORKS! I had it in my old Plymouth Laser a bunch of years back, and forgot about it, until the first really chilly days of fall hit. My wife came home from work one day and said "The heater won't get warm in the car". Went out and drove around hard; the temp gauge wouldn't go over 1/4 scale (normal was 1/2 scale - stupid no-numbers gauges... ). Drained and refilled the radiator with 50/50 - worked fine again.

thanx for the info....that looks like just what the doctor ordered for the new engine.
