will a one-piece radiator from a EF (d series) fit a B18A1 DA?

both are automatic applications..

 

What's a one piece radiator? Do they make a two piece radiator as an alternative option?

No, an EF radiator wont work in a DA without modification and hoses. It's not worth the trouble.

 

it should work, if you have the ef rad it prob isnt much different thank da. you got two trans cooler lines and two coolant hoses. you could actually block the transcooler lines in the rad if they are not fitting correctly and run with an aftermarket oil cooler for transmission. post some pics lets see what u got done.

 

ok so here is pictures. the first one is a radiator for 89 civic. second is radiator for 90 integra. it will work, you might need to get a new length of transcooler line from autozone or somewhere prob 2 - 2.5 ft so you got enough and you might also have to make a custom bracket to hold radiator in the da. i put the si radiator in my dx hatch.

 

please post a picture after install so we can check it out.

 

what i meant was a OEM full one piece not an small aftermarket radiator.

 

well i managed to install it. the tran lines seem to fit and tighten.
only issue is the d series hose is too small and b series is too big for the inlet and outlet on the radiator.
i don't know if i can use a specific clamp and just tighten it or what hose to use.

 

Lol U should have just bought the right one off eBay for 23 dollars
ef and da radiator are not compatible
that being said ur only option is to use a adjustable clamp if u want to keep trying

 

Easy fix... Z71036 - STEP UP / STEP DOWN SILICONE RADIATOR HOSE CONNECTION - 1 1/4" TO 1 3/4" your local rad shop or auto parts will also have step up/down rad hosing 94

 

You mean a full size versus a half size radiator. There is still no such thing as an OEM full one piece radiator.

Honda part number: 19010-P03-505 is a "small" half size radiator found in Civics and Del Sols. There is both an OEM full size radiator and OEM half size radiator

 

his orginal post says one peice from ef civic. he is not talking about the half radiators... ef civics only came with full size radiator.

 

What exactly is a one piece radiator? From my knowledge, there's only a full and a half size radiator option for Hondas.

 

his question was about a ef civic which only come with full size radiators, so your comment about a half size radiator is irrelevant.

 

OP original question:
Once again, what exactly is a one piece radiator from an EF?

 

what i meant was a full size radiator from an EF not a dual core or small radiator.

made it work with the correct clamp and size up size down hose.

had a spare EF radiator. don't drive the DA much so didn't want to invest $100 on a radiator for it at the moment.

thank you all for your help.
