Which engine coolant?

The service manual is very vague on this - "Subaru coolant". Whatever that means.
In previous years the car has been serviced at Subaru (by the previous owner, I'm not that rich) so I have no indication as to what's in the system. Any ideas?

I use Prestone.



The Subaru conditioner is just Radweld BTW.

Important coolant info: http://www.subaruforester.org/vbulle...-coolant-1059/

You can use non-Subaru brands too, but it needs to be non-silicate, non-phosphate and non-amine type.

Personally, I use which ever happens to be in stock at my local autofactor (typically Bluecol 2 year) - though I do change it every service.

Was: 3 x WRX, 1 x Foz XT
Now: BMW M235i + X1, Cooper S, KTM 450 EXC, Triumph Tiger XCx

What Silke said, the aluminium block needs a non-silicate, non-phosphate and non-amine type.

Non-silicate, non-phosphate, non-amine. Got it.

Do you add Radweld too? Is one 250ml bottle enough?

I didn't.

Look here: Prestone (yellow/extended life antifreeze/coolant)

Subaru specifies a non-silicate, non-phosphate and non-amine antifreeze. They also refuse to tell anyone which brands meet their specifications.

By law, Subaru cannot mandate Subaru coolant unless they provided it for free.

I spoke with a chemical engineer at the company that manufactrurers Peak Coolant last week for 40 minutes. Here's what I found out:

Peak Global is 100% phosphate and silicate free.

Virtually ALL coolants manufactured for the past few DECADES are non-amine. Therefore, nobody lists non-amine on their coolant bottles.

The ingredients in Subaru and Peak Global are identical except for minor differences in the anti-corrosion package.

The company that makes the anti-corrosion package for Subaru coolant also supplies Peak. That company has told Peak Subaru's anti-corrosion package is 100% compatible with Peak's. they are virtually interchangable.

In a brilliant marketing move, Subaru has managed to skirt the Magnusson Moss Act but telling us to only use a "non-amine" coolant. Since nobody's made a non-amine coolant for years, we're running around looking for coolant that doesn't have something that isn't around anymore.

It's like your doctor telling you it's OK to drink cola, but make sure the label says cocaine-free. How long has it been since Coca-Cola's ingredients included cocaine?

By the way, the guys at Peak are very familiar with Subaru, Subaru coolant and Subaru coolant additive.

As far as I'm concerned, Peak Global Coolant is the equivalent of Subaru coolant.

I'm using Halfords Advanced Antifreeze, which is an OAT coolant.

Halfords | Halfords Advanced Antifreeze & Coolant Concentrate 5 Litres

I made sure I flushed the system before changing.

I use Peak Global, the most convenient place I've found to buy it now Walgreens, sometimes it goes on sale for $8.99.

This kind:
