greenleg88 Posted August 19, 2008 Share Posted August 19, 2008 What is the capacity for the radiator? i just drained it and not much came out... only about a gallon went back in... when we flushed water into the engine, it would fill up and over flow the way we put it in.. (we put it in on the left side while facing the car going into the engine) that didnt really help the rest flow out any better on the bottom of the car either. it seems liek there was something clogged in the engine? why is that?

Strakes Posted August 19, 2008 Share Posted August 19, 2008 Your cooling sytem may be clogged. Or it has a big bubble of air in it. Check out the following links: http://www.ultimatesubaru.org/forum/showthread.php?t=84025 http://www.ultimatesubaru.org/forum/showthread.php?t=21681 http://www.ultimatesubaru.org/forum/showthread.php?t=66821 Burp the system. If you have a bleed screw on the top of the radiator...it's pretty easy. Next time, fill it painfully slow. Start out through the top radiator hose into the engine, then slowly pour coolant into the radiator. If you search the board using "burp", you'll notice that Subarus are prone to getting big air bubbles in their cooling sytems during coolant changes. Good luck!

RallyKeith Posted August 19, 2008 Share Posted August 19, 2008 The thermostat is at the bottom of the system, where the lower radiator hose connects to the engine. If you didn't remove the thermostat (and assuming it's a factory thermostat with the pressure relief hole) you will only get a small dribble out. Last time I did one I only remember putting in about 1.5 gallons or so with the system as drained as I could get it. Link to comment Share on other sites More sharing options...

Good luck! hmm thanks for the info. after reading those, ive learend a bit.. but.. doesnt loosening the bleed screw on top of the radiator only help the radiator drain faster? how do i get the air out of the actual engine block?

Strakes Posted August 19, 2008 Share Posted August 19, 2008 I ended up with a big bubble in our old 93's engine block. I filled the system up as best as I could. I opened the bleed screw, started the engine, & turned the heater on. I slowly poured coolant into the radiator as the thermostat opened up and let coolant in the block and pushed the air out through the bleeder. When coolant started to ooze out the bleeder, I closed it and shut everything down and put the radiator cap on. I was surprised at how much air was trapped in the system.

EVOthis Posted August 20, 2008 Share Posted August 20, 2008 prob. not the best method but sometimes you can redline it in neutral for a second to get the air out....i did the radiator on saturday in my 96 Legacy and for the life of me couldnt get all the air bubbles out...no matter what i did the bottom hose was still cold...so after running out of options i remember someone telling me you could just gas it a few times....worked for me....
