I’m almost positive 2.5s did, mine has a piece on the left and right side and the main middle piece is missing bc the previous owner took it off. Anyone with one local to western pa?

Does anyone still have the plastic skid plate that came stock on these cars laying around?

Does it make a difference if you use the blue disc on a drill vs just cleaning the surfaces with a gasket scraper? Is one better than the other?

I have a 09 2.5 with an auto. the car has 124k on it. i’m not sure if the fluids ever been changed before. should i change it?

Also I called several subaru service and parts departments and they said that you don’t need to replace the water pump because they hardly ever see them fail. should i replace that and should I also replace the thermostat when I do the head gaskets?

Does anyone know which year sti or wrx gaskets will work on an 09 2.5i? The dealer said there is two different head gaskets for the same year frame sti.

Are the sti gaskets multi layer steel like the six star ones?

Yup definitely the head gaskets. Pressure tested it today and you can see the coolant drip from the back of the heads on the bottom. When I do the gaskets I plan on using copper gasket spray. Anybody have anything bad to say about the stuff? Also on head gasket jobs i’ve done in the past we just cleaned off the mating surfaces the best we could with brake cleaner and a rag and put the heads back on. Is there a better way to do this without getting the heads machined? I’m afraid to nick the block or the surface of the head if I use a razor blade to clean it off.

So I have an 09 2.5 legacy and it has been losing coolant for about a month. The first time I noticed that it was a bit low so I topped it off and it was fine for about a week. Then I topped it off again a week later. Then it got to the point where I had to top it off every couple of days and I noticed a leak behind the oil pan near the crossmember. Now I have to top it off pretty much every time before I drive it. You can see coolant leaking out of the back of the drivers side head. I’m about to pressure test the cooling system after my car cools down to make sure I don’t have a leak somewhere else but my question is if I added some subaru coolant conditioner would it maybe slow down or maybe even stop the leak? I have had no other issues with the car. It never overheated, it doesn’t blow any white smoke, there is no bubbling in the overflow, and there’s no coolant in the oil. Thanks in advance for the responses.

Do you think it would raise the freeze temp enough to make a difference even if I got most of the water out?

If I didn’t pull off the thermostat do you think it would be fine because I have green coolant in it now and I’m putting in blue coolant? I don’t think it would be enough to make a difference but I have heard of people saying that green and blue coolant can’t be mixed.

So my 09 legacy 2.5 currently has green coolant in it, not sure if it’s subaru coolant or not. I planned on changing it so today I bought blue subaru long life coolant to put in it. I also planned on running distilled water through it to get most of the old stuff out. How could I do this to get most of the old coolant out? Also, should I use the subaru coolant conditioner? I didn’t buy it because I think it’s a scam. My head gaskets seem to be leaking a little bit and from what I’ve read adding the conditioner won’t help if they already started leaking. Thanks in advance

After reading through some other threads I decided to stick with 5w30 synthetic with my 2009 2.5i and change it about every 4,000 miles based on where I live (PA) and how I drive. I am hard on the car sometimes but I drive normally most of the time. My question is should I maybe go longer between oil changes or should I be fine changing it every 4,000 miles or so with synthetic? I’ve also been on bobistheoilguy and I still can’t make up my mind. How often do the rest of you guys with 2.5is change your oil and what do you use?
