I am the person with the 1994 toyot pick up that has (had) heating problems.I found out what the problem was.The shop that I let replace the radiator, sold me/ installed a POS "cheapy" radiator.I found a significant leak / separated weld around the tops inlet.They replaced the POS radiator with a CFS radiator.It is obvious (by simply looking at it) that this radiator is a MUCH BETTER built radiator.I would still like it to run a little cooler.Does anybody know of anyone that has ever used a coolant additive? Do they really make a dofference? I am planning on running water wetter with a 25-30 to 70-75 mixture of anti-freeze to water, and then add water wetter?Does anybody know if this will make a significant difference driving across AZ and NM during the end of october?
Mix the antifreeze 50/50. The more antifreeze you have in the mix, the hotter the engine will run>
I run water wetter. the least amount is the best, but you need to add enough so that the water pump stays lubed. Follow the directions on the bottle and use DISTILLED WATER don't use tap water. If you use water wetter don't use any other additive..Technically water by it's self is the best if you live where it doesn't freeze. yet running only water won't get you the lubricant your water pump needs. You are using a NEW radiator cap Right? don't use the old one!

Whoa! Use the recommendations of the coolant manufacturers, and you don't need to use additives with new coolant! There are no additives that will make it run significantly cooler, anyway, unless you are running straight water in your rad, which is stupid for a road vehicle. Additives are to re-inforce the ingredients in coolant that fight rust, etc. The only practical way is to increase airflow across the radiator, but then the engine may never reach optimum operating temperature, meaning it will use more fuel. Water wetter is said to reduce operating temperatures by 30 degrees, but read the information properly - IN SYSTEMS NOT USING COOLANT, in racing engines, and in systems with signicantly smaller cooling systems, or systems where people are too damn lazy to change their coolant often enough! A 50-50 water-to-coolant mixture is standard, as it offers protection against the maximum temperature ranges most of us will experience. 50% anti-freeze is also the recommended minimum for corrosion protection, 70% is the maximum concentration recommended, stronger and the stuff can start to gel and restrict the ability of the mixture to transfer heat. Between 50 and 70% the cooling at high temperatures is not changed much, the difference is cold protection, and the higher concentrations would be for areas like Alaska and the Yukon.
