Hello Peppers !

 

Hope everyone is doing well.

 

I have been busy with university stuff so took a break for tinkering with my car. Recently took the manifold and carb to home and cleaned them. Still looking for gaskets for intake manifold and 2-barrel carb. Also took apart the  water neck with the coolant air bleeder valve (that was also clogged but couldnt figure out a way to make it work, I tried to to blow through it but I couldnt because its clogged or something else. Looked up online for the passages but there is no clear pictures of it so if any of you have please share with me or I can send pics of mine and you can tell me whats wrong with it.

 

I also took apart the thermostat housing from the water pipe. Because the previous owner didnt use any antifreeze most of the water inlets and outlets are rotted and not in a good condition. Even more suprising part is, when I took apart the thermostat housing there was no freaking thermostat in it. There was just a black gasket of it and additional gasket maker to seal the crumbled mating surfaces. I was doubting my self thinking that I must have dropped the thermostat while disassembling the housing and stuff, but I checked the engine bay and floor twice in different days still no thermostat to be seen. The ends where coolant hoses go over are all crusted and mostly crumbled. Thinking about somehow finding a decent fabricator and weld in the same diameter inlets/outlets. 

 

Im thinking about filling and fixing the metal water neck and thermostat housing with metal filler and sand them down as close to original sizes. (I cant seem to upload / share photos on the forum I dont know why, but I have them on hand and send pictures of them to clarify their condition if anyone want to learn more, any help is appriciated :). So I was wondering when I gradually add antifreeze, will it eat away the metal filler / putty? If so Im open to any possible solutions or ideas.

 

Coolant hoses are also not in good condition, filled with rust residue and gunk. Im looking for complete coolant hose kits for EV2 engine but cant seem to find any. I have only found mishimotos set, which it says it will also fit to 84 civics. Mishimoto SKU for it is: MMHOSE-CIV-88RD . Here's the link for it where I looked up: (https://www.hoonigan...32242560893013)

 

When I check it on Mishimotos website it says its direct fit for 1988-1991 civics, 4th gens. So I was wondering will the coolant hoses fit to 3rd gens as well? Some looked similar but Im not really sure. EW's are similar to SOHC D series and most EW parts fit to EV2 as well, so that was my logic behind it.

 

I also found 5th gen hose kits localy which it also says fits to D14 and D16 same  family with the 4th gen SOHC engines, so if those also fit I might just grab them because they are cheaper. 

 

 

The car is just sitting in the car park because of the winter and Im just trying to get my hands on some parts. So it will most likely continue to sit till the spring. 

 

Im all ears for any suggestions or ideas they are all much appriciated. As I said I will gladly send the pictures of the parts via email if it helps for assesing the the problems or solutions better. 

 

This forum is my only hope for the info that Im looking for so please if you have any idea or opinion on it, please do share I would be grateful.

 

Thanks in advance for your help, wishing the best for everyone.

 

Sincerely,

Aras

I would go do a parts look up on a Honda parts site online.  You will see what other cars the part fits.  I did a quick search and it seems all of the 84-87 Civics and CRXs all shared the same radiator hoses, 1.3L and 1.5L here in the US.  Got to imagine it’s the same in Europe.

Yeah I know the hoses are usable on both 1.3L and 1.5L engines from 84-87. But the thing is there are no parted out 84-87 civics near me, only seen 2 other cars. 1st gen crx's never entered Turkey. Finding and importing from EU is really hard due to customs and expensive. That's why I asked about later generations. Some parts of EW's are usable with SOHC D series but not hoses afaik, later EW's became first D serires (EW4---->D14A4). Guess I'll bite the bullet and try the 4th gen hoses for D14 or ask around more for where I can get custom hoses. If anyone else knows please chime in. I use Amayama to check for OEM codes and compatibility by the way.

 

What about the damaged water neck and thermostat repair with polyester putty? Im still searching online for effects of antifreeze against polyester putty. Will that work or is there a more viable way to fix them? As I said I can send pictures of it but it doesnt let me post on the thread.

 

Thanks,

Aras

i’d need to see pix or p/n’s. best to look up the honda websites for p/n’s. i have good luck using those p/n’s and searching ebay

apparently, it’s best to use the old green antifreeze. it’s made for our metallurgy (copper radiator and the bypass tube in the back of the engine). i had put in toyota red anti freeze for 1995-2005 cars, i noticed it was making my copper radiator shiny when i opened the cap. green this is for older US cars. i believe newer radiator fluid eats away at the copper/brass parts via electrolysis. people have a hard time sourcing that copper tube in the back of the engine

i’ve got some background in metallurgy, more in polymers. i’d source new/used housing/outlet lubes. chemical reaction and temperature stress under pressure is risk. not familiar w the material you are using
Keepin' it OEM

Thanks for replying. Yeah green coolant for aluminum seems to be the way, thats what hayness manual says atleast. Still looking up on the organic and inorganic coolant types theres a lot of discussions on them just like engine oil lol.

 

OEM Numbers for parts that I am talking about:

 

Coolant Neck / Outlet: 19315-PE0-010

 

Thermostat Housings: 19320-PE0-000 & 19311-PE0-000

 

Trying to upload the pics of mine before and after cleaning with a wire brush and sandpaper but forum just doesnt let me upload I dont know why. Imgur or Lightshot also does not accept eventhough the files are in JPEG.

 

I can send them through email or any other way you prefer.

If they also fit later models they would have shown up on the list of other models that they fit.  No later models appeared, sorry.

Yeah sadly they dont. Im still thinking about getting a set then maybe cut them to fit if I can get a good deal. Probably not all of them would fit but I belive I can make it work with some "custom tailoring" lol. 

 

Thanks for the repsonse.

That’s a common thing to do with motor swaps.  Here in the US I would take the hose to a parts store and ask if I could look through their hoses to find something similar that I could cut down to work if needed.
