Hey guys, was just under my car to change the oil and noticed the reddish orange hose that comes out of the bottom of the motor and loops right next to the oil filter is splitting big time and is about to pop. Anyone know what this specific hose is called or have a part number? Is it a coolant line or an oil line?

Thanks in advance!

I'm having trouble imagining which line you're talking about. I might be having a brain fart but I can't think of any hoses that come out the bottom of the motor on a 92 SS. Any chance you could take a picture?

Unless... does your car have an oil-to-water cooler installed? Those only came on 91 models but maybe someone put one on your car. The oil cooler goes between the oil filter and the block, and has one hose that goes over to the water pump and one that goes up into the block.

Is that latter hose the one you're talking about? If it is, it carries coolant and has an ID of about 1/2". The stock one isn't red, though; it's black.

Subaru made at least three oil coolers that fit -- the one used on 91 Legacy Turbos, the one used on Foresters, and the one used on WRXes. There may be variants of those. Anyway, the important part is that the 91 oil cooler used a different hose than the Forester and WRX coolers. The old one is kind of U-shaped (which it sounds like yours might be, since you describe it as looping) and the new one is more like a 90-degree elbow. In either case, they are 11.5mm inner diameter, which is close to 1/2".

The old hose part number is 807611182 and the new one is part number 807611031.

If yours really looks like it's going to fail soon, replace it right away. A dealer probably will not have the hose in stock, but just ask any auto parts store if they have any piece of 1/2" heater hose that's about the right shape, or that you could cut to fit. If they don't, just buy two 1/2" heater bypass caps and cap off both fittings for the time being so you don't end up stranded. The car will run fine with those capped off.

Heres a picture. This is looking from the front of the car.
Hopefully this helps.

I can't tell for sure because there isn't much context in that photo and it's been more than a year since I've worked on a Legacy Turbo, but I do believe that nipple on the block is what the oil cooler uses. I can't clearly see it in that picture, but to me the oil filter looks too high up for there to be an oil cooler in there.

That's not a stock hose, and it doesn't even look to me like it's there replacing a stock hose. Where does the other end of that hose go? Looks like someone did some creative modifications or repairs.

Curious.

But in any case, that looks like basic aftermarket heater hose. Whatever it's doing, you should be able to replace it with bulk 1/2" heater hose from the auto parts store.

Yeah, that is certainly not stock. Where does that hose go?

Its fixed, i got a foot of heater hose and fixed it.. Its a coolant line that came out of the motor right there next to the filter and wraps up over the exhaust manifold and connect to another section.

You might want to figure out what the deal with that hose is... I feel like this hose failed because heater hose just shouldn't be that close to the exhaust manifold.

wrap that up in heater wrap and call it a day

Thats what I was thinkin too, but it had been like that since ive had the car for over a year now. So it lasted a long time.

A year's not a long time for a hose to last.

on cars with a cooler, that hose goes into the cooler, and then the outlet of the cooler goes across to the water pump where there is an extra inlet.

on cars without a cooler that port should be a blank plug and there shouldn't be an inlet on the left side of the water pump.
