Zerex Asian vs. Toyota "Pink" SLLC
I needed to do a drain and fill on my 04. I did not want to do a complete flush, just a drain and fill of the radiator. I plan on doing 2 or three drain in fills over the course of the next three weeks. I just wanted to refresh the coolant already in my system.
I read up on a lot of forums concerning the use of alternate coolants instead of using Toyota SLLC. One that typically came up was the Zerex Asian sold at NAPA.
I just wanted to post some pictures, prices, and the ingredients of both to give further resources to those looking at their options.
Zerex Asian LLC:
1) 50/50 Pre Mixed
2) Ingredients: Ethylene Glycol (107-21-1), Water (7732-18-5), Diethylene Glycol (111-46-6), Sodium Benzoate (532-32-1), Corrosion Inhibitors, Defoamers, Dye, and Bittering Agent.
3) Engineered by Valvoline for Asian Vehicles (Nissan, Honda, Toyota, Hundai, Mitsubishi)
4) Meets or exceeds ASTM D3306 & D4985
5) Price: $13.00/gallon (At NAPA Auto)
Toyota Pink SLLC:
1) 50/50 Pre Mixed
2) Ingredients:Water (7732-18-5), Ethylene Glycol (107-21-1), Diethylene Glycol (111-46-6), Sebacic Acid (111-20-6), Potassium Hydroxide (1310-58-3).
3) Engineered by Toyota for Toyotas.
4) Meets ASTM D-3306 & D-4340
5) Price: $19.00/gallon (At local Toyota Dealer)
The two were very similar but different. The main ingredients are similar but there are definite differences in the two compositions. Both are Ethylene Glycol based. Both have the the same temperature ratings.
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). Toyota Red and SLLC were said to be compatible and backwards compatible with Pink being the new and improved version.
I bought both but ended up returning the Zerex Asian. 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'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 used Toyota SLLC and did my first drain and fill (1 gallon). 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 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.
