My radiator started leaking from the top, which appears to be fairly common. So, I ordered a replacement Koyo unit online.

I just received it, and there appear to be 2 additional, smaller hose fittings. One next to the lower radiator hose and the other on the driver's side. It doesn't look like the stock radiator has these 2 fittings.

Did I get the wrong radiator?
The fittings have rubber caps on them. Am I supposed to use it with the rubber caps to block off the fittings? This seems like another source for a future leak...

Any help is appreciated. Thanks!

 

that should be correct on my 96 Civic when I bought a RAD for it it had those 2 additional fittings they should just be capped off.. They never leaked for me

 

its for an auto car you can use it for an oil cooler if you want

 

I was thinking they sent me a radiator for an automatic trans car....

Anyone strongly suggest I get one specific for manual trans car? Otherwise, I'm going to install it tomorrow afternoon.

Thanks everyone.

 

mine was like that too when I recieved it. I guess its some what universal to be used for auto or manual. I basically plugged/capped off those additional hose fittings or whatever

 

why does everybody plug these? if there's no fluid going through there, what's the difference if they're plugged or open?

Fluid does go there unless you plug it. Aftermarket radiators (for the most part) have those extra 2 fittings and unless you plug them, coolant will flow through them as well.

 

are the rubber plugs that come on the rad. good enough to plug them?

I ordered a radiator for my integra and it came with this **** to on the bottom. I took them off and nothin leaks out of them so I am with you on this one.

 

There is seperate tanks, it won't leak, no need to cap, seal, plug, blah, blah, blah. That would be a pretty crappy design if the auto tranny fluid went to those lines and was mixed with coolant, think about it.

 

Indeed, just leave them alone, nothing will make it through.
