What are your opinions on:

LubeGuard red (or similar) when doing an ATF change?

Water Wetter (or similar) when doing a coolant change?

Are these products functional? Worth it?

Ive used water wetter in all my cars and trucks. I use it in my drag truck (10 sec. club). I have noticed about a 5-8 ticks down with my 180 t-stat in the 00 bonne. Worth it

Thanks for the testimonial.

My objective is to keep my engine and tranny as cool as possible (yet still be within normal operating parameters).

You need to research the products thoroughly before using them.

IIRC WaterWetter is intended for warm weather use only. I believe the package says to remove it before winter or keep diluting it with antifreeze/coolant for the winter.

Definitly drain coolant and change over t-stat for winter. its part of the winter routine. Change your oil too to a 0w30.....helps for the cold mornings Its cold in Canada....i like my heater.

He may not have an issue with winter problems...check his location.

Althoooough, they've been having record cold in CA this year.

Thanks all.

I've already done 180 degree drilled thermostat and switch to Prestone. Temp gauge reads lower than before, but since the gauge doesn't seem to be linear, I will have to wait until my scantool gets here to see what my actual temps are (and to make sure I'm not running TOO cool!). I run 10w30 synthetic year-round.

In Southern CA, cold weather is not my issue. It can get blazing hot in summer, especially on the desert side of the mountains and between here and Vegas. That'* the main reason for the t-stat and my questions re: water wetter.

Anyone got anything to say about LubeGard?

No idea on the Lube..

The wetter though..did drop my summer temps about 5-10 degrees

Lubegard Red is a good idea for the tranny. It'* the ONLY thing besides ATF that I'd put in mine. I run it in every auto trans I own. I won't say that it will definitively keep it cooler (you should really run an aftermarket cooler for maximum cooling), but it'* properties will make it last longer. The rest of the additives are snake oil to one degree or another.
