Just wondering about everyone's positions for the radiator inlet/outlet?

I have a radiator where the inlet/outlet are on the same side (passenger).

Most of the radiators I see for the motor are on Top PASS, and Bottom DRIVER.

I have read and been told a KA radiator will work just fine, but I was wondering if this was the case, do I buy radiator hoses for the KA radiator as well?

I am probably going to be switching to a thinner radiator before summer so I can mount my dual fans.

I was just curious how many people were running radiators with the inlet/outlets diagonal from each other rather than on the same side. I've looked around at picture threads and stuff but can't really get a clear image/good angle to tell.

Thanks.

The Rad's with the Top Pass and the Bottom driver is for the SR.

Just buy a KA Rad.

Yes you can use KA Rad hoses.Thats what I'm using. (SOHC) I dunno, but I only can imagine the DOHC is the same.

Why don't you sell the Puller fans and keep your Big Rad and get Pusher fans.

I'm running a aftermarket Rad and 1 13" Pusher fan.So far the temp doesn't budge from 180.
