Question OK, do we really need "Subaru coolant" for radiator?

I jsut got my 2000 RS with 48,000 miles & thought I'g take it to the only freakin' sub dealer in the county to get the car a good checking out and my wallet a good lessening of it's contents.

I dropped about $290 on various things, and it occurs to me that the radiator has never been flushed, so I ask how much that cost, since in the manual it says to use only "subaru" coolant. Joe Service Manager says it would cost me $100 to flush and fill radiator!?!?!?!

I say hell no and take it to an all asian repair shop (1st time there) and they do it for $35 with brand X...can't remeber what brand, but I could find out if it really matter. I assume it was a quality, industry standard brand.

So what's up with the "Subaru" coolant???? Is it needed?

I have never heard of needing special coolant. Mine sure doesn't have Subaru coolant, and it seems to work just fine. I wouldn't worry about it too much.

Supposedly it's formulated to prevent any reaction w/ the aluminum block material that would cause mineral build-up in the longterm.

Honestly, it's probably just Prestone or some other brand re-labelled. I just figure for a coupla bucks more, why the hell not? Just do the flush yourself so you don't get killed by dealer labor charges.

not even CLOSE in consistency. Even when it's already cut with distilled water it's still 3 times thicker then Prestone or any aftermarket coolant. All i reccomend is using factory coolant in all vehicles.

HndaTch627,

Maybe so, but sometimes you need to fill up when you're not at the dealer. How much do they charge for a jug of that stuff at Subaru? I get this creepin' feeling that it's like $20, and that's pretty steep for coolant. Dropping Prestone into my radiator has never caused any problems.

So what's the argument? Seriously, I want to know.

Last time I was told to specifically get a part from the dealer it was my oil filter. I paid six bucks apiece for 4 filters, got home, and saw a big Puralator/Subaru stamp on all four filters.

If all the Subaru coolant is going to do is protect radiator down to (-)x degrees then I should be fine with prestone, etc, (since I live in TX).
Unless the sub coolant has more benefits than protecting at lower temps I don't think I'll mess with it. Please correct me if i'm wrong.

Also, I heard it's ok to pour coolant into toilet? Is this true???? The only reason I took it to a shop to get it flushed is becasue the only place that takes radioator coolant around here is 20 minutes away and only open from noon-4 PM on weekdays(Environmental Collection Center).

A gallon of Subaru coolant at full list price is $12.36, so you won't get killed in price for it at a local dealership. If it comes in a one gallon jug, I don't care who told you it was premixed, it's not . The text on the jug is as follows:

Quote:
(Insert poison control junk here)... The product contains ethylene glycol, dietheyle glycol, and inorganic/organic acid salts. Do not store in open or unlabelled containers.


It then goes on to "performance":

Quote:
Subaru Long Life coolant is an ethylene glycol base product for long-lasting aluminum and all other component's protection. Subaru Long Life Coolant has been developed to provide corrosion and rust protection of all cooling system components. Requires no additional corrosion inhibitors. A 50/50 mixture of Subaru Long Life Coolant and water is recommended for year round protection.

As for the freeze protection:

Quote:
50/50 Mix:
Freezing Point -34 deg F
Boiling Point 265 deg F

70/30 Mix:
Freezing Point -84 deg F
Boiling Point 276 deg F

So Brian do you basically agree that I ought to use Subaru stuff?

Your working at Exeter can't have any bearing on your decision.
Damn the man.

I won't tell you what I pay for it . In all seriousness though, other than it being perhaps a pain to go to the dealership and pick up, there's no real reason not to use it IMHO. It may be twice what other antifreeze costs, but Subaru makes coolant for the cars for a reason, and it wasn't to get $12 out of people. They made it because the wanted a coolant with certain life expectancy, freeze/boil characteristics, and corrosion inhibitors. If they could have used something cheaper (costs less I should say), and off the shelf with the properties they wanted, that you can get at any Autozone or PepBoys, don't you think they would have ?

Buy only the Subaru coolant. It is silicate free coolant which is less corosive on your engine internals. If you use dex-cool the mixture of the old and the new dex-cool will coagulate and gunk up on everything. Everyone talks about getting ripped off by buying this....OKaaaaay. Most mods are $200-$800 and they're worried about $5. Anyway, after researching all the posts about coolant on NASIOC thats what I found. Hope this makes your decision easier.

Yes, in fact in cold weather climate areas you are supposed to use anti-freese to keep your pipes from freezing in the winter. My family has a cabin up in the Sierra mountains, and we always use anti-freeze in all the sinks/toilets or the pipes will completely freeze up.

Well... I've never had to fill up my reservoir more than maybe a little bit here or there, at which time I used Prestone or whatever I had on me. The major fillups were always done at the dealership I assume, and I think flushes were done at 30k and 60k services.

Guess I'll buy some SOA stuff.

Hmmm. The bottle of Zerex Extreme I have in the basement (ok, now it's on my desk) has the following info on it:

Quote:
50/50 Mix: -34F Freeze, 265F Boil

Its patented extended life formula is phosphate and silicate free and helps protect engines from rust and corrosion for 5 years or 150,000 miles

Protects all cooling system metals, including aluminum

Oh - regarding antifreeze disposal: be careful if you are on a septic system; the antifreeze can kill the bacteria.

From http://www.epa.gov/grtlakes/seahome/...e/antifrze.htm

Quote:
The major components of antifreeze can be broken down by organisms in a sewage treatment plant. If your home is connected to a sanitary or municipal sewer system, household quantities of antifreeze can be flushed down the drain with plenty of water. The solution is not so easy for those homes with a septic tank because antifreeze can overwhelm the organisms in your septic system, causing damage to the system. If your wastewater goes into a septic tank, very small amounts over a period of time can be flushed with plenty of water. Better yet, ask a friend, relative, or neighbor who is hooked up to the sanitary sewer system to use their drain to dispose of your household quantity of used antifreeze. Do not pour antifreeze into storm sewer openings, sinkholes, or abandoned wells where they will directly pollute the water.

If you live in a warm climate, will distilled water and hy-per lube or water wetter provide enough corrosion protection?

I'm thinking no...
