Chase Bays Tucked Aluminum Radiator - Nissan 240sx S13 / S14 / S15 and R32

The Chase Bays Tucked Radiator for Nissan 240sx Silvia S chassis & Skyline R32 is designed for those wanting to open up space in their crowded engine bays, get a better look aesthetically, and improve cooling power. It offers more fluid capacity than most aftermarket rads, more direct airflow, & dual pass design. It has been shortened 8" of space but increase the width and thickness to compensate. This radiator has been rigorously track/drift tested for nearly a decade & is on countless show winning engine bays.

Chase Bays has designed this aluminum radiator to fill every bit of space under core support while still being able to run (2) 12” fans. This radiator requires some light front core support cutting. Chase Bays wanted to make the radiator as large as possible while staying under core support. To accomplish this they had to cut into the chassis. This radiator hits the stock S13 pop-up motors, but with this product it can be relocated: S13 Headlight Motor Relocation

Fans
The radiator is setup for our extremely high powered 12" Chase Bays Ultra Duty Fans that are 1,700 CFM each. 3,400 CFM total!! It's important that each fan is on its own relay w/ proper sized wiring & that fill point is actually the highest point in system. These 2 things are most commonly overlooked. For this reason we make Dual Fan Relay Harness w/ 180º F Thermoswitch and our Raised Inline Filler Neck (read more below).

The Chase Bays Ultra Duty Fans are 1.5 inches thicker than standard Slim Fans fans so they will take up more space. Luckily with this radiator you'll still have plenty of room on i6 and V8. 

Modular Inlet/Outlet and Reversible Orientation
The radiator inlet & outlet have to be on same side since it's a dual pass design. Chase Bays has designed the radiator to be completely reversible w/ interchangeable inlet/outlet types. 

Inlet & outlet are -20AN female threads.  If you change your mind down the road, there's no cutting & welding. Just threading on new adapters. 

KA/SR Upper & Lower: 1.38" (35mm)
RB Upper: 1.38" (35mm) & Lower: 1.5" (38mm)
1JZ/2JZ Upper: 1.38" (35mm) & Lower: 1.5" (38mm)
GM LS Upper & Lower: 1.5" (38mm)

Fill Point
The way you setup filler neck will make your hose selection easier. The best way to do this is to use the Chase Bays Raised Modular Filler Neck. It's raised perfect height to match original fill point height.

To do this select -20AN for 1 side of Chase Bays Filler Neck when selecting options, other side will be whatever hoses you choose to go with. So if you're using OE Push-On style Silicone Hoses, you'd select "1.38mm Normal Hose" for 1 option & "-20AN" for other. -20AN side will thread right into radiator then you'll twist filler neck onto that. W/ thick O-Ring Seal on both sides, getting filler neck 0º vertical is easy w/ adjustment of both sides.

Dual Pass Design
This simply means coolant passes through TWO times instead of ONE. Which, more simply put means TWICE the cooling & half the size. Inlet & outlet are on same side of radiator & the end tank is made as two completely separate rectangle cube pieces to block flow between upper and lower. Radiator has 2 L brackets on each side that you bolt to your core support. This radiator doesn't use any OEM radiator mounting points.

Hoses
Factory hoses don't work.  You must piece together silicone hose bends w/ small joining couplers & use Gates Heat Shrink Clamps for a seamless install.  Click here to set your hoses up.

Pressure Tested
Each radiator is pressure tested to 30psi. Your radiator shouldn’t see more than 16-19psi before radiator cap spring does its job & expands into overflow.
