Sapper 157 Posted May 1, 2018 Share Posted May 1, 2018 Hello all. I usually am over in the Old Gens, but given recent circumstances, I am having to retire my old Blue 84' wagon. Standing in as its replacement is a 2005 Subaru Forester auto transmission with 125,000 miles on it. it has the 2.5, which has had regular oil changes. (the car is a gift from an elderly couple who keeps their cars in good shape). According to their mechanic, the timing belt will need to be changed soon, but other than that, I am planning the following as a tune up: Spark plugs & wires (NGK), rad cap, OEM thermostat, new coolant, service the battery, change transmission fluid and filter, fuel filter, and air filter. Is there anything specific to this engine/transmission that I should hit with my tune up? I know they are known for HG issues... how worried should I be about that since they have never been done? Any other maintenance recommendations to help make this car a reliable daily? Link to comment Share on other sites More sharing options...
GeneralDisorder Posted May 1, 2018 Share Posted May 1, 2018 HG's need to be done. They are leaking externally. That's a fact. I don't even have to look. Needs a new radiator and hoses if it hasn't been done. Plastic. Rubber. Fail. Timing belt is WAY overdue. 105k or 10 years whichever comes first. Could break anytime. Change immediately.

GD Dang okay. Looks like im gonna be pullin the engine. I'm guessing OEM only on HG correct? FelPro no good? As far as new radiator, found one on rockauto by a company called TYC. For timing belts I am looking at AirTex. Think they will work or is there a specific brand for radiators or timing belts for these cars? sorry for the rookie questions Edited May 1, 2018 by Sapper 157 Link to comment Share on other sites More sharing options...
idosubaru Posted May 1, 2018 Share Posted May 1, 2018 1. New timing belt and pulleys from Subaru or Aisin 2. Ignition tune up and fluids like you said 3. Add front diff fluid Fuel filter is pointless to replace. Around 2005 they moved the filter to the tank, so if that's yours you can't just easily swap it in the engine bay like older ones. But it doesn't matter, it's pointless as Subaru filters dont' clog unless you have some massive catastrophic causative issue. I have 285,000 on my daily driver and 200k on gobs of subaru's with original fuel filters, yaaaawn, never gonna matter. If the filters are getting clogged then you better pull your entire pump and replace the pump due to the pre-filter, sock/screen. Inspect the headgaskets first. I bought a 2005 for a friend, she drove it for years and I sold it for her this year. Always dry as a bone, nothing but plugs, wires, and timing belt. 1 Link to comment Share on other sites More sharing options...

I didnt realize that about the fuel filter. I wont be able to get to the car until late june so that doesnt help. Ill add changing the diff fluid as well.

GeneralDisorder Posted May 1, 2018 Share Posted May 1, 2018 Denso or Koyo for radiator. Aisin for water pump. Mitsuboshi belt, NSK/NTN/Koyo idlers. NTN tensioner. Dealer HG. Order the gasket for a 2008 STI. Part number ending in 770. All other gaskets from Subaru. GD 2 Link to comment Share on other sites More sharing options...
Sapper 157 Posted May 1, 2018 Author Share Posted May 1, 2018 (edited) Found this Aisin kit on eBay: https://www.ebay.com/itm/Aisin-TKF001-Engine-Timing-Belt-Kit-With-Water-Pump/112960719404?epid=227929600&hash=item1a4cfbca2c:g:W6gAAOSwzJ5XZs6c&vxp=mtrProduct bulletin: http://www.aisinaftermarket.com/uploads/68y84rq7_TKF-001_TIMING_BELT_KIT.10-07-11.pdf In the PB above it says its for a manual trans only... is that correct or will it work fine for an auto trans? Also I found the HGs you were talking about GD. Thanks for pointing me in the right direction. Edited May 1, 2018 by Sapper 157 Link to comment Share on other sites More sharing options...
GeneralDisorder Posted May 2, 2018 Share Posted May 2, 2018 (edited) Need to check your water pump. Some of those Foresters have a weird front facing nipple for the oil cooler. We generally just delete the oil coolers and opt for synthetic oil instead. Even the 08+ WRX's came without oil coolers stock so it seems like overkill for an NA forester. They also leak and the hoses go soft from oil contamination. You can use that kit if you dont have the nipple or if you delete the associated cooler.

CNY_Dave Posted May 3, 2018 Share Posted May 3, 2018 On the head gasket, my take would be even if leaking fix or not based on how much it leaks. On the oil cooler, here where it gets cold in winter, I think it serves a good purpose as an oil heater. Link to comment Share on other sites More sharing options...
Sapper 157 Posted May 3, 2018 Author Share Posted May 3, 2018 (edited) Yeah ill probably hold on to the oil cooler for now. Definetly gonna do HGs... ive heard and seen too many friend's 2.5s failing. I do have what may be another "newbie" question... would this bearing set work for my cars timing? https://www.ebay.com/itm/Idler-Bearings-Tensioner-Kit-911-82005-Forester-2-5L-SOHC-99-05/272667954248?_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D50544%26meid%3D4d5fe1d256484fd697d58cbaf78e66e6%26pid%3D100005%26rk%3D4%26rkt%3D12%26sd%3D302313888648%26itm%3D272667954248&_trksid=p2047675.c100005.m1851 It says only for manual trans but i know these internet vehicle part match things are not always accurate. Would this kit work with the 4EAT forester? Edited May 3, 2018 by Sapper 157 Link to comment Share on other sites More sharing options...

Sapper 157 Posted June 2, 2018 Author Share Posted June 2, 2018 Any particular reason to use the 2008 sti HG (p/n 11044AA770) instead of the actual HG for the 2005 Forester (p/n 11044AA642)? Link to comment Share on other sites More sharing options...

They will work fine also. They are not the gasket for a 2005 Forester NA. Is this a turbo model? If it is, those gaskets don't usually fail.

Sapper 157 Posted June 4, 2018 Author Share Posted June 4, 2018 Okay thanks, I was just curious. Nope not a turbo. Link to comment Share on other sites More sharing options...
Sapper 157 Posted June 22, 2018 Author Share Posted June 22, 2018 Should I remove and clean the fuel injectors as long as I have the intake mani removed? Also, tips/guidance for removing the engine without accidentally pulling out torque converter with it are much appreciated. I have read it is a nightmare to deal with, and would like to avoid it.

GeneralDisorder Posted June 22, 2018 Share Posted June 22, 2018 Just remove the dust shield on the bottom of the bell-housing when you have the engine pulled up in the cradle. It's not anything like a "nightmare". We do it daily and my tech's don't complain about it all. The injectors are likely just fine. I wouldn't mess with them.

1197sts Posted June 25, 2018 Share Posted June 25, 2018 If you really want to make the engine last you may want to consider changing the oil pump, at least take the back plate off and inspect it. Subaru put smaller oil pumps on these engines for some reason and it is a weak spot. GD would be a good source for this, but if I recall correctly a 10 or 11mm pump is a good upgrade.

GeneralDisorder Posted June 26, 2018 Share Posted June 26, 2018 A 10mm pump is a good idea. Link to comment Share on other sites More sharing options...
Sapper 157 Posted June 30, 2018 Author Share Posted June 30, 2018 Unfortunately, I’m already pretty strapped for cash so I think I’ll kick the oil pump upgrade down the road. I got the engine off without any trouble from the TC. Decided I’ll leave the fuel injectors alone. Link to comment Share on other sites More sharing options...
