I know what works for my vehicles, like everything else, choose the path you're most comfortable with. Nothing coming out when some of these have been drained, flushed with clear water and refilled the same way after 3 years and 60k+ miles. No build up of any kind in the system, reserve tanks, etc. Each vehicle completely flushed with straight water then refilled with 50/50 Prestone green coolant and distilled water and the prescribed amount of Water Wetter added. My vehicles and methods eliminate all that. How many of those experiencing issues in actual vehicles had coolant in there beyond the recommended change interval and/or cross contamination of topping off with non-compatible coolant or stop leak or any other form of radiator treatments or flushes? All possible variables unaccounted for. All of these have had Water Wetter added: Computer geeks hot rodding up liquid cooled computers.what does that have in common with motorcycle or automotive cooling materials and systems? Even the car board, there were those already on the 1st page stating they've had no slime or negative effects.īased upon my real world experiences since 1999, there are no ill effects. I call into question half of those posts. Worst case, I'll just stick with the regular old ethylene glycol. I also believe that engine ice just recently gained approval by AMA but haven't really heard from any of the local racers using it. I know water wetter is popular amongst the road racing community as it has been one of the only approved coolants that you can run in AMA and other racing organizations. I want to know, from real world experience, if anyone can attest to the abilities of one or both of these products. but of course they're gonna say that their product works wonders. I've read a little on each manufacturers website and they each claim to drop temps, increase mileage blah, blah. (I know the V doesn't have a temp gauge so you really can't tell if the temp drops). If so, did you notice any improvement in performance, etc. My question is, has anyone out there in the V world tried the water wetter or engine ice coolant brands. Good luck trying to find that, in my opinion it is just easier and safer to buy the Toyota specified product and change it every five years or so.I am currently about to flush my coolant system and have been tossing around the idea of replacing with water wetter premix. Toyota states that in order to avoid technical problems, only use “Toyota Super Long Life Coolant” or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with long-life hybrid organic acid technology. In some cases they can be substituted for one another and sometimes not. Today there are many different types and formula coolants. Then early antifreeze was developed that had a one or two year life and compared to adding alcohol was considered permanent. That alcohol evaporated rather quickly and needed to be check regularly. Regarding “permanent” antifreeze, years’ ago to prevent the water that cools an engine from freezing, alcohol was added. Coolant/Antifreeze WaterWetter - 12oz, doubles wetting ability of water to reduce temps by up to 20f, rust and corrosion protection for reduced coolant levels or straight water, compatible with all glycol antifreeze, cleans and lubricates water pump seals. The level should also be checked during oil changes. Toyota also recommends that coolant level and condition should be checked at least every year or 15,000 miles. Clean coolant not only protects your vehicle’s engine from freezing in the winter and overheating in the summer but also acts as a lubricant and corrosion inhibitor. ![]() The coolant in your Toyota does not last forever and will deteriorate through a combination of age and contamination. Toyota recommends replacement of engine coolant at 100,000 miles, then at 50,000 mile intervals thereafter. You can find the exact service intervals for the 2008 Highlander coolant here, at Toyota’s online maintenance schedule for the Highlander. Does this coolant/antifreeze last the life of the car and is this the only kind I can use? I thought I remember reading about permanent antifreeze is there such a thing?Ī. When I got home I was reading the owner’s manual and it referenced Toyota Super Long Life coolant. ![]() My 2008 Toyota Highlander was in for some routine service and the advisor recommended that I replace the coolant. Maintenance intervals have stretched double, triple and longer in the last decade, but how long exactly does “Super Long Life” coolant last in a Toyota Highlander?
