roger1 Posted August 12, 2004 Share Posted August 12, 2004 I replacing the coolant and would like to get all old stuff out as it's about 3 years old. Is it those large flush plugs with the hex opening? As I remember they were slightly different diameters. If it is they are sure much easier to get at than the 1.8 OHC's. Off topic of my post, I used a Subaru timing belt and had marks on belt with number of teeth between sides and crankshaft. Really handy for this shadetree mech. Do the other parts houses do that too?

Bill90Loyale Posted August 12, 2004 Share Posted August 12, 2004 Is it those large flush plugs with the hex opening? Yes. Two of them. 14mm allen size, I think. Let us know how it goes removing them. I'm planning on doing the same with my wife's 95 legacy. Quote Link to comment Share on other sites More sharing options...
DerFahrer Posted August 12, 2004 Share Posted August 12, 2004 I have a much more unorthodox method of cooling replacement, but it's never failed me. I just drain all the old coolant out, and stick a running garden hose in the radiator. I start the engine up, and just let it run like that, water pouring in the radiator, circulating through the cooling system, and draining out the other side of the radiator. You can do this for a while, the cool water will keep the engine cool. Once you see pretty clear water coming out of the radiator drain, shut the engine off, and turn the hose off. Then add your new coolant, burp the radiator properly, and wa-la! You have a clean cooling system Quote Link to comment Share on other sites More sharing options...
Guest jclay Posted August 12, 2004 Share Posted August 12, 2004 Where exactly are these plugs you speak of? I'm swapping in a new radaitor this weekend, and figure that while i'm at it, might as well drain the block coolant. the garden hose method sounds very tempting... jared Quote Link to comment Share on other sites More sharing options...

Bill90Loyale Posted August 12, 2004 Share Posted August 12, 2004 Where exactly are these plugs you speak of? On both sides of the oil pan. One for each side of the block. Quote Link to comment Share on other sites More sharing options...
