Duel pass radiator - Lateral-g Forums

I think this might have been discussed before, but what is the difference between your standard aluminum crossflow radiator vs. a duel pass radiator. Besides the obvious difference that both inlet/outlets are on the passnger side, is there a performance or cooling gain? Thanks.

We sell and install dual pass on every application we can. We see as much a 15 to 20 degree additional cooling on water heaters. We see higher temp drops from the inlet to the outlet on dual pass. On or cross flows we will see a right around a 30 degree drop and on a double pass we can push near 40 degree temp drops

Fan, Fans, Fans. Fans are your friends. Try to find a way to get at least a pair of High Performance 13s on your radiator. And make sure they are on a professional built shroud. Most radiators systems show their inadequacy at the worst time when you need them the most. When your sitting still, in high heat, A/C on cause no air is moving through the cabin. Nothing sucks worse then having to shut off the A/C and roll down the windows cause the car is warming up. Then once you roll down the window the old lady starts warming up.........................then you hear Michael Buffer, Let's get ready to RUMBLE!!

One more question. Clearance is kind of tight in my engine compartment and I might have to use a set of "pusher" fans. I have heard from different sources that pushers don't cool as well as pullers. Well why do they sell the dang things? If I'm sitting in traffic with no airflow, my fans, regardless of location, are going to be cooling the radiator. Lemme know cause I'm getting ready to make a purchase.

I have never seen a set of pusher fans that were worth anything. How much room do you have between core support and accesories?
