23 Coolant Hoses

All of the hoses looked to be in good condition on the outside. No obvious checking or cracking or getting soft and there were no signs of impending aneurysms. There was no obvious checking on the inside visible from the ends; but, I did not go to the length you did of splitting the complete length of each hose to completely examine them.

If I cleaned them up, wiped them with a little silicone spray and put them back in the original bags I might have been able to pass them off as new - except for the scores in each end of the big hoses which were required to get them to release from their spigots.

Similar update here for my recently acquired 91. Prices seem to be nearly 100% higher from 2019 alone. I think the SOS kit is only missing a few of the hoses and relatively comparable in price but when you add in what SOS charges for drop shipping vs an acura/honda parts warehouse and the additional gaskets and odds and ends for whatever project you are already working on, it made sense for me to order from a warehouse.

My winter timing belt job quickly spiraled into so much more:

Adding context - shipping took about 25 days so a little bit of a backlog. I was told that the delay was actually due to a pair of sway bar bushings (52316-SL0-010) but hopefully this information helps anyone looking to purchase similar parts and can plan for some downtime.
 
I just ordered a complete set for 2001 from Impex and they had everything in stock except the reservoir overflow hose, which I wasn't going to replace anyway, since it's failure would be minor. No problem with the LHD hoses which often cause delay.

Plan to order soon. Did you have to order each individual part or do they have a kit with everything?

I wish, but no, no kit from Impex. There would be quite a few different kits. I got a list from @Old Guy , which was 1997+, MT, LHD. If you can't find model-specific list from someone, you'll have to look at the parts diagrams. You could look at @Old Guy 's list with the pictures from the parts diagrams to help you make the list, but yeah, part of what you're paying for from SOS is the right list of parts made into a kit. Compared to SOS, ordering it all individually from Impex was ~1/3 cheaper, but after the shipping difference, it was more like 20% cheaper. In hindsight, might well be worth going with SOS. It was a quite a chunk of time with the Impex order, entering 20 parts, double checking 20 parts, triple checking 20 parts, waiting for a shipping quote, paying for the shipping separately, ... but since I had a bunch of other stuff including a door handle I needed, I was adding onto that order. <Ramble off>

Thanks for the info. I'll probably just end up getting a kit from the links above. I see Mita has a clamp kit as well. Did you re use the clamps or did you replace them?
 
If you don't go crazy flexing them the clamps are re usable. I did purchase one of each style clamp (so not a complete set) in case I broke a clamp or one popped off and landed in some hiding spot in the garage. However, I did not lose or break any clamps so all my spares remain in their original plastic bags.

I did the same. I ended up re-using all of the clamps since I was careful on removal. As long as they are not corroded or flexed beyond their stress point, you are fine to re-use them.
 
Was checking the hoses to inspect whether the previous owner has replaced them.
Does 12/94 on the hose means the manufacture date?

Same with me, I ordered an extra clamp in each size just to be sure. A set of needle nose pliers with curved tips made the job easier. Having a garage lift made the job so much more easier, especially for my old back. I don't know about you guys, but I am on my third coolant tank in 21 years. Jerry
 
The oil cooler hoses are f******* little buggers. On the NA2 cars the heater hose is also a bugger because the power steering rack makes access a pain. The later cars have a revised lower rad hose which is way harder to get back on than it looks like it should be. I eventually got mine back on with a lot of silicone grease; but, I think loosening the rad so you can move it around a bit may be the way to go.
Agree that revised lower rad hose is tough and took grease, soaking it in boiling water, and a few unprintable words. The heater hose above the EPS is not bad if you remove the battery and the EPS connector bracket.

However, I don't see how I can get the one deeper oil cooler hose off/replaced without disassembling the axle or something. Who's done it and how?

Long reach 90 degree needle nose pliers really help with the oil cooler hoses. Also, LarryB taught me to completely remove the oil cooler pedestal from the engine block and also remove the CV heat shield from the inboard joint. This way you can move the assembly around to help with access. Getting those hoses off is nearly impossible without cutting them. If you can just pull the hoses off then you have accomplished a miracle. The only way I've been able to do it is by scoring the ends of the hose with a new razor blade until I've cut through the rubber enough to get a pick under the hose and tear it away from the metal nipple. You must take care not to score the metal with the razor or it can create a leak! Once it's cut like that, you can pull it off with the pliers. These two hoses alone will take 2-4 hours of careful scoring with the razor and manipulating the clamps to pull the hoses off. To install the new hoses, warming the ends up and using generous amount of "pool lube" help immensely. This job sucks so bad that I only do it now with the engine out, but it is doable with patience.
