Valvoline Zerex Red Asian Vehicle Coolant

That app is called Honey? Never heard of it.

 

Yes. It's actually a web browser extension. If you look up a product on Amazon, honey will search for better price from other retailers and automatically apply coupons for you so you get the best price.

 

Actually my bad calling it an app. It is a Chrome extension. Pretty handy at times.

 

Just wanted to post another picture of the stuff.

... but you can also use Camel Camel Camel or TryCamel app to track prices fluctuations of products.

 

As opposed to starting a new thread, I wanted to ask: will the Zerex mix with the OEM coolant fine? I have drained my block and removed the radiator for a timing belt swap on my 2004, but hopefully won’t have to drain the heater core.

In the past, color meant something, but it doesn’t anymore. What does matter is ethylene glycol vs propylene glycol and the way they react with one another. But I’m not sure if it’s that simple, or other factors come into play. Now that a few years have passed, just wondering if there’s any more recent info on any problems I might encounter just buy refilling with Zerex?

 

I'll just offer my experience for what its worth:

In 2019 I bought a 2014 Scion tC (Basically a 2 door camry) from CoPart that had a hydrolocked engine. I replaced it with an engine from a 2013 Rav4 and while they shipped it mostly empty of fluids, they couldn't have removed all of the coolant from the block plus whatever was left in my heater core. I put in Zerex in and have been driving it with zero issues for almost 4 years. It seems to mix fine.

Zerex checks all the Toyota boxes I believe.

 

Yeah, as valuable as the forums are for info, imo they are rife with misinformation when it comes to things like oil and coolant. Especially since the products are continually advancing and usually faster than the information. It drives me crazy the pro-OEM crowd who act like the vehicle manufacturer is producing their own coolant or oil. Somebody out there is making the stuff for them. (You should try being on the dirt bike forums. Those are some arrogant but uninformed people).

As it is, I couldn’t find the Zerex, so I settled on the Peak Asian pink “OEM” (their word on the bottle). I can’t imagine it being any different. It was a little more expensive at $18.50/gal diluted, but at this point, I’m tired of my truck being down. I just want it back together.
