automatic transmission cooler lines

[adecanmin]

How many have the originals? My hoses are not leaking. Should I replace these 27 year old ones? For anyone who has replaced them, where did you get the hose Autozone, Advance? I saw a roll of it for sale that supposedly fit. I'd hate to disturb the hose to find out the hose I purchased is too big or too small to slip over the fittings.

there's no need to replace them if they're not leaking unless you just want to dress up your engine. You can't just change out the hose yourself, they are hydraulic lines and the ends need to be swage-crimped in place.

Good advice. With my car the rubber part of the line is actually held on with constant pressure clamps. I've removed them before to install my radiator. I've never had had an oil (fluid) line fail before it leaked. I've had water lines split. Water seems to be harder on rubber then fluids seem to be. I don't know of anyone who has 27 year old radiator and coolant hoses that have never been changed.

dang it, I was thinking of power steering for some reason. yeah, you should be fine unless they start leaking, but if they do, it's an easy enough fix. If you need to know for sure what size and if you have enough slack in the hoses, cut a bit off of the end, like less than an inch and clamp the rest of the hose back on if you need to use your car to get to the parts store.

I think the engine cooling hoses are subject to a lot more pressure than the transmission lines are. The highest mileage auto transmission I had was in the 254,000 mile range, still had the original lines on it. I don't think I changed any of these lines in the seven or eight automatic Accords I've had (that weren't parts cars).

I'm at about 345k. The transmission lines are hard to the touch. As are my power steering lines. No leaks yet.

Yeah, they get hard, and the wire clamps kinda dig into the rubber, reducing the squeeze and allowing leaks. I've replaced a few of those clamps with wider band/screw clamps ( without removing the hose) to stop the leaks.

good tip

I may have even left the old clamp in place and just put the band clamp next to it.
