Meeky Moose Posted January 13, 2004 Share Posted January 13, 2004 didn't they come with a coolant overflow tank? the one i just picked up didn't have one, and it just pumps the antifreeze out on the ground in very small amounts.. and in 2 weeks time its about half empty.. it only does it on short drives (5 miles or so) now i put my ea82 coolant overflow tank in there where the jack goes (since theres no other place for it) but i'm still stumped somewhat.. and i'd like to put my jack back in its spot..

Skip Posted January 13, 2004 Share Posted January 13, 2004 Tony, did you change the rad cap also? They are special for overflow systems. My Brat does not have an overflow (funny thing just today, I was thinking of adding Ol'Tw's to it ) I do not think it should be dumping that much out of the over flow. If you fill it to the rim, it will dump some and seek a level and should hold there. Could you mount the jack in the spare tire? Quote Link to comment Share on other sites More sharing options...
CIS Subaru Posted January 13, 2004 Share Posted January 13, 2004 I've never heard of any EA81 car that came with an overflow tank. There's a tab inside the radiator that marks the MAX fill level. If you fill past that tab, then coolant will likely drain out onto the ground. Quote Link to comment Share on other sites More sharing options...
Meeky Moose Posted January 14, 2004 Author Share Posted January 14, 2004 ahh, well someone has replaced it before me with a standard 13psi cap.. maybe its got the wrong cap on it.. which would make sence if they bought it for an 89 subaru, lol.. ya gotta buy parts for an 83 or 84 to get the right stuff for this car.. guess i need to go check out a cap for an 83 and see what the difference is.. well with the tire in the spare tire area theres no room for the jack.. the handle still fits under the tire tho..

NV Zeno Posted January 14, 2004 Share Posted January 14, 2004 I installed a reserve tank in my EA81 years ago. Didn't have to move anything around under the hood, either. I got a generic reserve tank kit from Kragen. It was a square tank with a mayonnaise jar sized cap. Came with a mounting bracket that can be easily modified to mount near the jack...mine's been there prolly 10 years now, no problems.

beauregaardhooligan Posted January 14, 2004 Share Posted January 14, 2004 Meeky, the only dumb question is the one you don't ask. CIS Subaru is correct about EA81s not having an overflow tank. They are double row radiators with a larger top to allow for expansion compared to EA82s with a single row, smaller top, and overflow tank. If you fill it past the level tab, it'll just spit it out when it gets hot. A common problem is overfilling the radiator, then refilling with water when it burps. After several cycles of this you end up with diluted antifreeze. A 13 psi cap is correct. A overflow tank certainly won't hurt, but, as Skip says, you need a different cap.

junkyardgabe Posted January 14, 2004 Share Posted January 14, 2004 another thing is on your short trips the thermostat isn't opening in that time and that pressure has built up and blows out the excess Quote Link to comment Share on other sites More sharing options...
Meeky Moose Posted January 14, 2004 Author Share Posted January 14, 2004 great.. thanks for the tips and info everyone.. Quote Link to comment Share on other sites More sharing options...
LostWater Posted January 15, 2004 Share Posted January 15, 2004 Tony, when I put an ea-82 rad in my hatch, the only place I found for the tank was the same that you chose, right where the jack goes. I would like a picture of that one NV Zeno did to see how he mounted it. Mark Quote Link to comment Share on other sites More sharing options...
Meeky Moose Posted January 15, 2004 Author Share Posted January 15, 2004 i found a place for it over on the passenger side, but thats a long stretch of hose to go that far, lol.. it could also sit behind the ac pump.. but it would rub there and i fear it would spring a leak sometime.. you'll get to see little Junky when i get that windshield from ya Mark.. p.s. my back seat tops are perfect except for a 1/2" tear in one..

beauregaardhooligan Posted January 15, 2004 Share Posted January 15, 2004 junkyardgabe, I must respectfully disagree about the thermostat holding pressure. It only stops coolant from flowing thru the radiator. The pressure will be equal throughout the system. Quote Link to comment Share on other sites More sharing options...
