May 14, 201213 yr 96' EJ25 DOCH outback wagon- my girlfriend and i drove up hill from mountain pass. we notice temp. gauge going climb up to overheat and saw smoking under the hood. we pull over and saw the coolant box's by the radiator were broiling even inside the radiator broiling too. Seem coolant not even through into engine. so, i was thought it's water pump broke and new replaced timing belt kits too, do am i right? what you think it's problem solving. thanks.
May 14, 201213 yr Yep.........head gaskets........your 96 has a reputation of blowing head gaskets. Do a search here on this website for "head gaskets," to read lots about it.
May 14, 201213 yr Head gaskets Classic head gaskets. You just noticed the most telling symptom. Most important thing is to not keep doing this. If you stop overheating it just HG replacement may do. Keep driving it and a 2.2 swap is the cure.
May 14, 201213 yr headgaskets. you can verify that we're right by either listening to us or going to the auto parts store and getting a kit that tests for exhaust gases in the coolant. but my muffler had no coolant smoking?that is not a failure mode of this engine, so you won't see that. not all engines have the same failed headgasket symptoms. as a matter of fact no EJ25 from 1996-2010 will exhibit oil/water mixing or coolant out the exhaust, which are what some people typically look for. they don't fail that way. headgaskets - they are pushing exhaust gases into the coolant - heating it and causing it to hydrolock, not ciculate, overheat, and boil.
May 14, 201213 yr There is a tool that percolates the gasses from the top of the radiator through a blue fluid. If it turns bright green, the cooling system is contaminated with combustion gasses. That's the first step in confirming your headgaskets are gone.
May 15, 201213 yr Author got you. i already tear down but timing belt DOHC...hard to removed sprocket. so, seem need buy the large pliers jaw for removed camshaft's sprocket before out the camshaft?
May 15, 201213 yr No, you will break or chip the cam pulleys. Take the valve cover off, there's a spot on each cam you can grab it with a wrench, I think a 1 1/16 fits? It's been a while.
May 16, 201213 yr If you need cam pulleys let me know. I have a set of 4 I pulled for another member already pulled that he ended up not needing. Usually folks just need the right side. I put them in a kit I call "the dreamers kit" or "I'm feeling lucky kit" often for folks that had a timing belt break or idler fail, valves collide, and they think it's just the cam pulleys that broke during the crash. It includes both R side cam pulleys, a used timing belt, and used idler of your choice. Enough to make you realize jus thos screwed you are and that the engine needs to come apart. Then I have heads for when you realize what the real fix is. Again it's usually just the R side. They will need the cam sprockets at some point anyways. I seem to sell about 4 of these sets per year. Infact I'm almost out of them.
May 16, 201213 yr Author how is smart are you! Really, i use large clamp lock on the belt make this stay before remove camshaft's sprocket. No, you will break or chip the cam pulleys.

May 16, 201213 yr how is smart are you! Really, i use large clamp lock on the belt make this stay before remove camshaft's sprocket. I had a friend do that and he paid $100 for a new sprocket from the dealer because he needed the car running that weekend. The sprokets are fragile and the bolts holding them to the cam are usually brutally tight.
May 17, 201213 yr Author thats good for when i can install camshaft's sprocket...i need to know what torque on it?
