I then poured more coolant from the jug thru a strainer and saw more of this substance. cups of the Zerex coolant I noticed white flaky material in the bottom of the cup. I normally just pour from the coolant jug, but got anal as I wanted to know exactly how much went back in during this first change/refill. of Zerex Asian Formula - red label - to use as a replacement. A little different story than the other Zerex coolant threads.Ī couple of weeks ago I changed the factory fill coolant in my '15 Tacoma 4.0L - it too uses Toyota's SLLC. This is an old thread, but I do not like starting redundant ones, so I'll post what I have to say here. I didn't do in depth analysis on this but wanted to post my observations and pics for others to use as a reference when looking at the same issue. I will be doing a second drain and fill next weekend, and then do one drain and fill every year as preventative maintenance to keep the coolant fresh. I used Toyota SLLC and did my first drain and fill (1 gallon). I'm sure the Zerex Asian would work fine but with the price difference being only $6.00/gallon there was no reason for me to cut that corner. I would not mind using the Zerex Asian if i was doing the total flush but I did not want to mix the two and leave it like that long term. I bought both but ended up returning the Zerex Asian. Toyota Red and SLLC were said to be compatible and backwards compatible with Pink being the new and improved version.

I found many people who said using Zerex Asian was ok, however most of them stated they were doing a full flush of all the antifreeze and not just doing a drain and fill or topping off their existing Toyota Coolant (Red or Pink). Both have the the same temperature ratings. The main ingredients are similar but there are definite differences in the two compositions. I just wanted to post some pictures, prices, and the ingredients of both to give further resources to those looking at their options.Ģ) Ingredients: Ethylene Glycol (107-21-1), Water (), Diethylene Glycol (111-46-6), Sodium Benzoate (532-32-1), Corrosion Inhibitors, Defoamers, Dye, and Bittering Agent.ģ) Engineered by Valvoline for Asian Vehicles (Nissan, Honda, Toyota, Hundai, Mitsubishi)Ģ) Ingredients:Water (), Ethylene Glycol (107-21-1), Diethylene Glycol (111-46-6), Sebacic Acid (111-20-6), Potassium Hydroxide ().ĥ) Price: $19.00/gallon (At local Toyota Dealer) One that typically came up was the Zerex Asian sold at NAPA. I read up on a lot of forums concerning the use of alternate coolants instead of using Toyota SLLC. I just wanted to refresh the coolant already in my system. I plan on doing 2 or three drain in fills over the course of the next three weeks. I did not want to do a complete flush, just a drain and fill of the radiator. No need to overthink.I needed to do a drain and fill on my 04.


These aren't your grandfather's (or even your younger you) cars. Seems like there's an awful lot of waste going on when it comes to fluid changes on cars these days. For that vehicle I use only Toyota OEM or Denso filter inserts. My GF's Lexus IS250 has been getting 10,000 mile OCs since there is nothing fancy about the cartridge filters I use. The oil was still serviceable and had adequate TBN and viscosity remaining. I did have a UOA done after the first 30,000 mile interval and posted the results at the time.

I'll let y'all know if and when the engine blows up. My current OCI is 15,000 miles or one year using M1 EP 0W-20. I did three of the 30,000 mile OCs on the Mazda with microGreen filters before the company went out of business. I drove that car for 23 years (353,000 miles) before ruining it in an accident. I started doing 10,000 mile OCs in 1990 on my 89 Honda Accord (with any brand of synthetic 10W-30 that I found on sale). I don't plan to ever change it unless I have to open the system. I've been adding RMI-25 to it every 15,000 miles and the coolant still looks almost new. I have 121,000 miles on the factory FL22 fill. I've been doing plenty of experimentation on my 2012 Mazda3. It's made for "forever" use in OTR trucks. My go-to replacement coolant is Peak Final Charge.
