vs
Antifreeze PEAK or OEM Toyota
Reviews
The Peak coolant that is the correct color for your year, i.e. pink for the MkIV, is fine. I have been using it for several years with no problems.
Pros: no problems for years
Vehicle:
Volkswagen
I ran the euro Peak without issue for about a year but I was bleeding coolant and in desperate need of the cooling system overhaul.
Pros: ran without issue
Vehicle:
BMW
My car is currently filled with the Peak Euro Blue stuff, works fine, identical to the OE BMW formula anyway
Pros: works fine, identical to OEM
Vehicle:
BMW
I personally use Peak brand coolant, and I've never had an issue for 100K+ miles.
Pros: no issues for 100K+ miles
Vehicle:
Subaru Forester
Mileage: 160934 km
The green does "work" but it wont help the health of the engine long term as there are chemicals in the Toyota red which help protect the engine, fittings, rad etc. Buy the right stuff from Toyota and it'll last ages, the wrong stuff will screw things up long term.
Pros: protects engine, lasts long
Cons: green coolant harms engine
Even though most will say to stick with G12/G13, I think that is where that "sand" comes from. I decided last year to completely drain the system - including engine block - and converted to Peak antifreeze. I have not had any problems since.
Pros: no problems since
Cons: sand in heater core
I did this a few weeks ago on my '13 Sequoia, but I did not flush it. Just drained the rad and the valves on the block. Replaced with Toyota red and distilled water at 50/50. The fluid I drained was as clear as the fluid I replaced, so I felt flushing was not necessary.
Pros: clear fluid after drain
Cons: no flushing needed
Vehicle:
Toyota Sequoia
Toyota brand coolant is top notch, supposedly can last for the entire life of a car and never needs to be replaced
Pros: top notch, lasts entire life
