in case you end up with an aftermarket radiator that has a 32mm (1.25") upper hose neck, this particular Gates hose will work. Meaning....you have a SOHC engine.

I would advise using new adjustable clamps at both ends. Part number is in the picture.

 

looks bloated af.

 

I've never had a problem slipping a d-series hose over the radiator outlet for the b-series

 

it does..doesn't it? No worries. It's a new hose. Hope you do realize the ends are different sizes...hence 1x1.25

this is the easiest method instead of trying to massage the stock D series hose onto a 32mm hose neck. Plus, the hose only costs $12, not $50+ for some silicone one.

 

stock hoses fit fine for me too

 

what's the size of the upper hose neck on the aluminum radiator? ^^^

I had a brand new hose from Honda and it was a PITA to fit mine. That's why I had to look for one with a 1.25" opening on one end and 1" on the other.

 

Good find. What about those rubber hose adapter inserts?

 

It was for sure larger than the original radiator neck. I had to use some oil from the dip stick on the radiator neck and slide the original hose over it.

 

Nice find!!!

 

I have not seen one that goes from 1.25" to 1". That's why I had to look for the formed hose from Gates' website.

 

One thing about worm clamps is you have to remember to snug them up every so often as the EPDM rubber compresses.

It's my understanding why spring clamps are used by manufacturers, less messing with over time. Spring naturally tightens as rubber "shrinks".

 

Performance Radiator includes them with EG Civic rads. That way no sep part # for the B16 del Sol...

 

I've had to do this for the mishimoto radiator as well. I will have to replace sooner than usual. Not suppose to stretch it this much.

 

Good point. The one I use is pretty decent and I haven't had to adjust it.

 

What about the lower hose? Doesn't that one also have a bigger neck on the aluminum rads?

 

I don't think so. I think the B series only the upper hose was larger, go figure.

 

Both hoses are the same size. "B" series hoses are 1/8" larger in diameter than "D" series hoses.

 

Good to know, thank you for the correction. Better to have proper information available.
