PaSprinter24 Posted February 16, 2013 Share Posted February 16, 2013 ok so wat im getting from this is that prestone wouldn't work/ shouldn't be used on our cars?

compsurge Posted February 17, 2013 Share Posted February 17, 2013 Just get Peak Long Life if you're worried. Prestone is probably fine. The change interval is what's more important. Link to comment Share on other sites More sharing options...

SBT Posted February 17, 2013 Share Posted February 17, 2013 Your mileage may vary... some coolants are aluminum alloy block friendly, some are not... and therefore your longevity (mileage will vary) if you don't use the Subaru-specified coolants items. I've always used Subaru coolant iand conditioner in all my Subarus. Had six at the time of the original posting, now down to four. No problems with the Head Gaskes in any due to proper coolant change procedures and proper coolant. Therefore YMMV if you use other than Subaru cooalant products. - Pro amore Dei et patriam et populum - Link to comment Share on other sites More sharing options...
PaSprinter24 Posted February 18, 2013 Share Posted February 18, 2013 ok so I should be alright then using the prestone and the conditioner for 30 thousand miles and then switch back to Subaru coolant? Link to comment Share on other sites More sharing options...
SBT Posted February 18, 2013 Share Posted February 18, 2013 I think the key will be whether you use distilled or tap water. There's so much chemical elements in tap water that it makes sense to not introduce that into your cooling system where it will have a bad effect. If you haven't done it already, then my recommendation is to get the Subaru coolant and use that with the distilled water. Take the Prestone back. But that's just me. - Pro amore Dei et patriam et populum - Link to comment Share on other sites More sharing options...

_karu_ Posted April 25, 2013 Share Posted April 25, 2013 Is there a bleeder nipple of some sort that you can use to let the air bubble out? Link to comment Share on other sites More sharing options...
_karu_ Posted June 15, 2013 Share Posted June 15, 2013 Do I need to dilute the OEM Subaru Coolant? Link to comment Share on other sites More sharing options...
SBT Posted June 15, 2013 Share Posted June 15, 2013 Which type did you buy? Long life or Super long life. First you dillute, second you don't - Pro amore Dei et patriam et populum - Link to comment Share on other sites More sharing options...
_karu_ Posted June 15, 2013 Share Posted June 15, 2013 I just checked the coolant that I just bought and it's the Long Life one. I also bought the conditioner as well. I guess I'll have to dilute it. I re-read the thread and found the instruction you posted before on how to dilute the anti-free, thanks! 1 gallon should do it. Per the tech manual, the cooling system holds 7.7 U.S Qts (MT model) and 7.6 U.S. Qts (AT model) which is nearly 8 quarts (2 U.S. gallons). To maintain the recommended 50/50 antifreeze to water dilution on a MT model, you'd need ~ 4 Qts (3.9) of Subaru OEM AF and ~4 Qts (3.9) of distilled water plus the 4 ozs of Subaru Cooling System Conditioner. Should be good to go. Good thing I asked before I put 2 gallon of Long Life into the car! BTW, any idea about the bleeder nipple? Is there such thing in my 2.5i 4 EAT?

_karu_ Posted June 15, 2013 Share Posted June 15, 2013 Gotcha. I was actually referring to the bleed screw though. In Honda's, they typically looked like this: http://techautorepairs.com/images/bleed-bolt1.gif From what I've been reading, it seems like our car doesn't have such thing. I've read the instruction and there is no mentioning of loosening a bleed screw to let the air bubbles out. Link to comment Share on other sites More sharing options...
SBT Posted June 15, 2013 Share Posted June 15, 2013 We don't. I'd follow the how-to that I posted.

_karu_ Posted July 14, 2013 Share Posted July 14, 2013 Does anybody know how to drain the coolant from the reservoir tank? Can we easily take out the bottle? Or, is there a drain plug at the bottom of it? Link to comment Share on other sites More sharing options...
MaStaMooN Posted July 15, 2013 Share Posted July 15, 2013 If I want to just replace the upper radiator hose, will it be as easy as drain only enough to get the pipe off and the new one on, then fill? Or will there still be the need to go through the entire burping procedure? Jon - vBGarage Profile Link to comment Share on other sites More sharing options...
compsurge Posted July 15, 2013 Share Posted July 15, 2013 Only one way to find out! I'd recommend doing the burp. I can't see any way that you won't introduce a nice slug of air into the system. It will leak a lot out of the engine side due to the pressure head of the coolant in the radiator . Link to comment Share on other sites More sharing options...
SBT Posted July 15, 2013 Share Posted July 15, 2013 It will completely drain your turbo coolant tank and likely pull (by gravity-feed vacuum) coolant from the top of the motor so you'll introduce air into the system. Don't replace the hose without doing the purge process. - Pro amore Dei et patriam et populum - Link to comment Share on other sites More sharing options...
RustyShackleford Posted July 15, 2013 Share Posted July 15, 2013 Does anybody know how to drain the coolant from the reservoir tank? Can we easily take out the bottle? Or, is there a drain plug at the bottom of it? On my car (same as yours, not sure if turbo is the same) there's just one bolt and you can remove the thing. Then you can give it a thorough cleaning too. Link to comment Share on other sites More sharing options...

Or, is there a drain plug at the bottom of it? There's one or two bolts at the top and the bottom fits into a post slot IIRC. Undo the bolts, take the hose off below the radiator cap, and lift it out. Clean it out with Simple Green or the Purple stuff and wash it out. Make sure you rinse it really well, several times to get any residue out of the bottle. Reinstall in reverse sequence. - Pro amore Dei et patriam et populum - Link to comment Share on other sites More sharing options...
