April 16, 200619 yr help !!!!!!!!!!!!!!!!!! how do you bleed air from the cooling system , i read it a few months ago but cant seem to find it . my car has the famouse water noise in the dash board i have a legacy 2.5 please help...........
April 16, 200619 yr Idle engine with the rad cap off until the fan comes on. Top off, mount cap again.
April 16, 200619 yr Setright has nailed it that is the way I do it and it works fine. Idle engine with the rad cap off until the fan comes on. Top off, mount cap again.
April 17, 200619 yr thats how i do it, the other method suggests putting the front of the car on ramps to bleed it. nipper
April 17, 200619 yr Author i jacked up the front and did as setright said , a heap of bubbles came out large and small and when i turned the car off a few more went in to the over flow bottle is that normal leaving it over night to cool any other advise
April 18, 200619 yr When you mount the rad cap, there will be a delay before the cooling system builds enough pressure to push expanding fluid past the rad cap. Once it does, it WILL cause bubbles in the tank because the hose connecting them is empty to start with. But why did it happen after you switched off the engine? Fit a new, genuine cap before going further.
April 25, 200619 yr Don't forget to milk the upper radiator hose to squish the air along with all the useful advice you already received above.
April 27, 200619 yr I'm not a fan of squeezing the hoses, you are just as likely to suck air back in. If your rad has a bleeder screw that should be out too, of course.
April 27, 200619 yr Get one of these and don't look back: Lisle #22150 http://www.automotivetools.com/online-store/scstore/p-LIS-22150.html **** ******!
April 27, 200619 yr Biltz, thanks for that great link. I can't tell you how much I dislike slowly pouring coolant into a Subaru just to avoid those darn "air pockets". Have you used that Lisle coolant thingy? Do you like it?
April 27, 200619 yr am i just incredible lucky? i have never had an airpocket in the cooling systems, and ive changed raditaors, flushed em, changed T-stats and waterpumps, never an issue. nipper
April 27, 200619 yr am i just incredible lucky? i have never had an airpocket in the cooling systems, and ive changed raditaors, flushed em, changed T-stats and waterpumps, never an issue. nipper i'm getting ready to flush mine (99 OBW 2.5 DOHC) i can't decide if i should just flush with water, or use one of the products available. i've got a net T-stat, so i'll flush it with it out. the headgaskets have been done so i was thinking of using comercial flush. what do you think? when i'm done i'll replace with antifreeze and distilled water.

Flush with water. DO NOT use a product. if you been flushing regularly there is no need for it. FLush products can remove everything holding your system together. nipper

FLush products can remove everything holding your system together. nipper well...i just got the car with 70k on it, the heater doesn't seem to put out like it should, i thought maybe someone had put the "treatment" in it so i was going to use a product to try and clean it out. HG's have been done, i figured i'd be okay with something recommended for aluminum. but, water it is....thanx
April 28, 200619 yr well...i just got the car with 70k on it, the heater doesn't seem to put out like it should, i thought maybe someone had put the "treatment" in it so i was going to use a product to try and clean it out. HG's have been done, i figured i'd be okay with something recommended for aluminum. but, water it is....thanx two words "reverse flush" . i flush via the heater hose (get a kit). Its amazing what comes out. DId you use a OE t-stat? The pipes in the heater core are huge compared to the radiator, so heater cores dont clog as easily as they used too, if ever. nipper
April 28, 200619 yr Have you used that Lisle coolant thingy? Do you like it?Oh yeah man, several times. It's just cheap plastic crap but it works really well. I actually learned about that device on USMB about 2 years back ...somebody posted a link to it. Harbor Freight carries it too. **** ******!
