because it warps and leaks if you reuse it when you put in a new thermostat

Your doing it wrong then.
I've still got my original plastic one on the car from when it was new in 2002 and 10+ coolant changes. |

Phase 1 2.2 should be metal. I have to agree with bobbyjimmy though if yours is "warping" you're doing something wrong. |

Another vote for "you're doing it wrong".

OP if you are having leaks, are you using an OEM thermostat gasket? I used one that came with a timing belt kit and coolant pissed out the housing, the gasket was visibly too thin when compared to the oem gasket. |

Fair warning, I really don't know for sure that part number is metal and not plastic. It's just the oldest 2.2 water neck so I'm going on assumption.

i'm actually just going off what my friend told me i should do i.e. get a metal one or always replace the plastic one. She has worked on numerous subies and knows them in and out...maybe here in TX the coolant doesn't cool down enough before entering the housing.
results may vary, yada yada yada. Mine is metal but i'm ordering parts for my friend... |

The one on your 2004 TS is metal? If so the part number is the same as what I listed before. So it's metal.

talked to my other friend and she said the warping can be caused by a previous owner over torquing a plastic one. plastic does dissipate heat better though... |

Not even close. Plastic is an insulator. Aluminum is literally about 1000x better at dissipating heat. Not that the heat dissipation ability of the thermostat housing matters in the slightest. |

It does exist!
It took a bit of doing, and I found this forum, sans answer, in the process of attempting to locate it, so I'm going to necropost the answer here. I'm sure the original poster has long since found one or decided not to bother, but perhaps someone like myself still looking will be helped, since my web search for "aluminum thermostat housing subaru" consistently hits this forum.
The part number is 11060aa061 and the application is apparently pretty universal. I found it here https://www.subaruparts.com/oem-part...ing-11060aa061 although I have simply used the application to order one through a local parts supplier with whom I have an excellent relationship. I expect the one I get will be Dorman 902-5052 as my parts supplier is not the Subaru dealership, but there's another valid part number for you! It appears this thermostat housing will fit any Subaru engine made in the last 30 years. I will put it on a 2000 Outback for sure, and a 2004 Forester XT I just grabbed recently but haven't scoured for issues and put on the road yet, if I find it doesn't have one. I agree with the OP: the plastic ones are too prone to warping, and I've lost several to that, plus plastic definitely IS more prone to catastrophic breakage. I'm glad I looked one more time; I had admitted defeat and stopped looking. Last edited by GreatNorthernDad; 02-27-2021 at 09:20 AM. |
