My 2009 Impreza Outback sport has been experiencing some persistent coolant leaks. I am quite new to working on cars so I have come to you all for help! Initially I thought that it was coming from the coolant hoses connected to the throttle body, so I replaced them, replaced the throttle body gasket, and cleaned the throttle body as well. After attempting to drive it I noticed that when the car got hot and up to pressure the leak was still ongoing paired with quite a large amount of coolant loss. I was able to catch a glimpse of the coolant hose that connects to the air intake manifold on the drivers side (about two inches from the throttle body and slightly under the throttle body’s drivers side coolant hose) leaking coolant. After the engine cooled, I checked out that hose and found that it was absolutely crispy, it had no elasticity to it what so ever. I ordered the part and replaced the hose. Now I’m seeing a coolant leak from that same spot where the hose meets the air intake manifold. I do not have a pressure tester though I will be picking one up shortly. despite this I’m confident that this connection or hose is where the coolant leak is. My questions are as follows: what is the hose fitting that screws into the air intake manifold and allows the vacuum hose to mount on it called? why does this coolant hose have no clips (doesn’t seem to on diagrams I have seen) and could this be an issue? There were no clips on the initial hose and it obviously ran fine for year. Is it possible that its the fitting thats gone bad and not the hose? If so any advice on sourcing and properly replacing it? Thank you everyone! -
Today I discovered very, very low oil and coolant levels in the Forester, and at 200000 KM I am hoping for good luck and a simple gasket change. As far as I can tell there is a delicate oily rainbow on the surface of the coolant in the radiator (difficult to tell with fresh pink coolant and brand new clean oil, and maybe this is possible under normal circumstances). I check levels more or less weekly, and until today all was OK... I have not noticed steam, smoke or whatnot from the exhaust, but I am alarmed at the rate at which the oil has suddenly gone. I am going to run the engine to temp and make a visual. What is more obvious is the fact that there is no external oil leak (I recently replaced the gushing plastic oil separator plate and crank main seal, and everything is still dry down there) but coolant has been spraying itself around the radiator top hose and cap area. Over -pressurised cooling system? I am going to drive the car down to my workshop and start to dismantle. I have ordered two standard genuine gaskets, 11044AA483, in the hope that I shall be lucky and the aluminium is fine. Regarding the head bolts, (can of worms) I have done a number of head geaskets on various vehicles, always renewing bolts, where recommended, possible or economic - why not? I notice on this forum (and others) some heated discussions regarding this topic. I dont see it mentioned in the official Subaru Forester workshop manual - they say USE NEW GASKETS, but the bolts are not mentioned. Looking at the torques applied, and compared to some cast iron diesels i have work on, one could agree that they are reusable... Wish me luck PS the car is a 1999 SF Forester I, 2.0 N/A , totally stock standard, maintained with genuine parts (even down to the Geolandars), family runner, regular oil, general maintenance, NO racing, doughnuts, drag or burnouts. I do enjoy brisk driving. Thank you in advance for any gems- SAVE THE FORESTER!! -
92 Loyale with 187K. 2WD. Is there a way to guess if this is just a blown Head Gasket or a cracked head? The car has been losing coolant for a couple of years. Now the temperature started rising. I introduced compressed air in all the cylinders at TDC. At the cylinder #2 the coolant started leaking from the radiator. I am a fairly conservative driver, drive around the town and do not rev the engine. What do you guys think? Regard, Sam
