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! -
I have a 1990 subaru legacy manual Trans and I've been having quite the idling issue. I just replaced the MAFS and she still won't idle what so ever. I'm planning on cleaning my throttle body and replacing the gasket to see if that helps. I've already replaced the top end throttle body vacuum line and it didn't do anything to help. I need some wisdom due to this being my first import please help me out -
I have an 03 Outback 2.5 A/T w appx. 184k miles. Trans has been replaced and the previous owner took good care of and maintained the vehicle well. The past several months I have had starting/idling/stalling issues. This general is worse when the vehicle is cold. It is hard to start without giving the accelerator a little help it most of the time will not start and keep running. It will stall if the idle is not kept up but when it does it runs fine. Sometimes it will idle and or start on its own without help, but that is generally only when it is warm, however can periodically do so on a cold start. When it stalls out, often the "AT Oil Temp" light flashes. The car is not throwing any codes. When these issues first started the symptoms where worse and the idle on a few occasions started to run high on its own, yes while driving which was quite dangerous! A few weeks back I ran some Seafoam into the intake into two different areas as per the bottles instructions to try to ensure that all cylinders where feed properly with the remains in the fuel tank. I also cleaned the throttle body out the best I could (air filter good, pcv valve iffy.) I did not get the standard heavy white smoke on start up that I normally do on other vehicles leading me to question whether the process took properly. I had a mechanic tell me to reset the computers values by disconnecting the negative lead & touching it to the positive side and leave set for 15 minutes or so. All of this seemed to do the trick. However, it started again and I brough it to my mechanic. The only thing they could find was a reported vacuum leak next to the intake. That certainly could do it and assumed that when I reassembled the air cleaner, I must have not made a proper connection and was gald that was the problem. It was not. THe car is still doing the same thing. I am going to try and replace the fuel filter and pcv valve next but if that doesn't do it, I am stuck! Suggestions!?! Btw: The TPS switch was tested and all that seems to be good. Please HELP!?!
