DESCRIPTION
This product is sold as is. Contains scratches and/or dents.
Although this product has slight imperfections it is still 100% in working order. Every Radiator sold as Scratch & Dent has been pressure tested to ensure there are no leaks at this time.
Please note that the pictures of this product shown are examples. Not one product has the same imperfections. Each numbered unit specifically correlates to the available unit # in the drop down options.
We also have a select few Tucked Aluminum Radiators that are New In Box from returns or exchanges. These are not shown (still in original packaging) and are also available for purchase under the same regulations and included parts as the Scratch & Dent versions.
Product includes:
• Tucked Radiator Specific to Chassis Listed - Scratched or Dented
• 2x Pre-Installed 1/8" NPT Plugs
• Fan Mounting Hardware Nut and Bolt Pairs
These Radiators have minor scratches to the outside but have never had fluid ran through them or used in any cooling system. They do not come with any 20AN ORB Adapters to the various hose connections that are applicable - those are available HERE.
The Chase Bays Tucked Radiator is designed for those wanting to open up space in their crowded engine bays, improve cooling performance, & get a better look aesthetically (tucked). It can practically work for any engine swap or configuration you come up with. This radiator is a cooling upgrade, it offers more fluid capacity than stock, more direct airflow, & dual pass design. It's mounted under core support to open up 6" of space. This radiator has been rigorously track tested & is on countless show winning engine bays.
We've designed this all aluminum radiator to fill every bit of space under the core support. This radiator requires some light cutting of front core support. We wanted to make the radiator as large as possible while staying under core support. To accomplish this we had to cut into chassis.
We've integrated a lot of features that no other competitor is offering. From fan sizing to modularity. We'll start at...
Fans
We've designed this all aluminum radiator to fill every bit of space under core support while still being able to run sizeable fans to keep your setup cool. Although there are many factors in keeping a car properly cooled, we'll assume you have all your bases covered (good water pump, no leaks, sufficient wiring, etc). It is important that each fan is on its own relay with proper sized wiring and that fill point is actually the highest point in the system. These 2 things are the most commonly overlooked. For this reason we make a Dual Fan Relay Harness with 180º F Thermoswitch that greatly simplifies the wiring (couldn't be easier).
The Tucked Aluminum Radiators listed do not come with fans, only their mounting hardware.
The Honda Radiator has accommodations for 1x 10" Fan and 1x 8" Fan
The BMW Radiator has accommodations for 1x 16" Fan
The Nissan Radiator has accommodations for 2x 12" Fans
Shroud
EVERY radiator comes standard with fan mounting shroud tabs on both sides of the core. After 15 years of track testing we have developed a solution that is still more efficient even at speed. RACE and DRIFT tested!
Modular Inlet/Outlet and Reversible Orientation
We have designed radiator to be completely reversible with interchangeable inlet/outlet types. Radiator inlet & outlet have to be on same side since it's a dual pass design. Formerly when you purchased a radiator through us you would have to select driver or passenger side. With our new design the radiator orientation is completely reversible. It looks the same on top & bottom & brackets are centered.
The inlet & outlet are -20AN female threads. So we install whichever adapters you need. If you change your mind down the road, there's no cutting & welding. Just threading on new adapters. We offer OE style 1.38", -16AN & -20AN. We recommend you put radiator inlet/outlet closer to upper water neck since that hose will more visible.
We do NOT recommend -16AN for high power setups! (400hp & up) Stock inner diameter of hose for Honda's is usually 1.38" / 35mm. -16AN is 1" & -20AN is 1.25" By going w/ -16AN, you're creating a restriction that's normally not there & reducing flow by 34%.
Fill Point
Since top of our radiator sits about 8" to 12" lower than stock, we have to make a new fill point. First step is getting an inline filler neck, luckily you can get that through us.. Click here for Chase Bays Raised Modular Filler Neck.
The way you setup filler neck will make your hose selection easier. Our personal favorite is on radiator itself using Raised Inline Filler Neck. We've attached photo of this below. To do this just select -20AN for one 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 one option & "-20AN" for other, -20AN side will thread right into radiator then you'll twist filler neck onto that. With thick O-Ring Seal on both sides, getting filler neck 0º vertical is easy with adjustment of both sides:
The other option is putting it on upper water neck which will require some fabrication work.
Eliminate the BMW expansion tank w/ this radiator if you place the fill point on the radiator. Just use a sufficient plug on the side inlet under the intake manifold & the fill point is on the radiator. This applies to M50, M52, S50, S52, S54, M60, M62, S62, etc.
Hoses
Factory hoses don't work. We piece together silicone hose bends w/ small joining couplers & use Gates Heat Shrink Clamps for a seamless install. We've been drifting our E36 non stop w/ no issues with this. Click here to set your hoses up.
Dual Pass Design
This simply means coolant passes through TWO times instead of ONE. Which, even more simply put means TWICE the cooling & half the size. Both inlets are on same side of radiator & a plate is welded inside between the two inlets. Radiator has two L brackets on each side that you bolt to core support. This radiator doesn't use any of OEM radiator mounting points, & it's easier to install & un-install.
Pressure Tested
Each radiator is water pressure tested to 40psi. Your radiator shouldn’t see more than 16-19psi before the radiator cap spring does its job & expands into overflow.

BMW Chassis Mods
E30 lower bar has to be cut (see photos) & hood latch has to be removed plus surrounding hood latch metal trimmed. The lower bar isn't structural.
E36 slight trim to the upper grille valence on left & right side.
E46 requires no trimming at all.
You can’t run AC w/ this radiator since it takes its place. You could custom fabricate a forward mounted condenser & extended lines.
An intercooler can work w/ some metal valance trimming on the E30. For the E36 & E46 light bumper trimming
Due to the BMW Radiator being smaller than our Nissan offering, generally anything over 450hp will need a larger radiator.
S Chassis Mods
This radiator hits the stock S13 pop-up motors, but with this product it can be relocated: S13 Headlight Motor Relocation
