If you've decided to add modern power to your ride using an LS series engine, this LS Swap Radiator Kit is the perfect way to protect your investment and ensure proper cooling system function.
We wanted to offer a solution for the budget-minded builder that also kept aesthetics in mind. Instead of an inline hose adapter with an NPT bung for you to plumb in your own fittings, which can look like junkyard parts hacked together and is susceptible to leaks, we created a unique LS Steam Vent Radiator Hose Adapter. This adapter makes quick work of several LS swap radiator hose issues with one simple piece. It features one 1.25" end to match the water pump outlet, one 1.5" end to match the upper radiator inlet, an integrated streamlined 1/4" 90° hose barb fitting for the steam line, and a black finish to blend in with radiator hoses. The combination of this adapter with one of our professional-quality aluminum direct-fit radiators means your search for an affordable and effective LS conversion radiator solution is over.
LS Steam Vent Radiator Hose Adapter Features
- 1.25" end - matches water pump outlet size
- 1.50" end - matches upper radiator inlet size
- Integrated 1/4" 90° hose barb fitting for a streamlined look
- Black finish blends in with radiator hoses
This LS1 Swap Radiator Kit features our 1966-70 Chevelle/Impala Aluminum Radiator. These high-performance radiators feature 100% all-aluminum construction and include a built-in transmission cooler. The furnace-brazed core increases durability compared to other radiators with epoxy-glued or crimped-gasket sealing methods. Two rows of 1-inch aluminum tubes allow this radiator to out-cool a similarly sized radiator with five rows of copper tubes. A rugged billet aluminum filler neck with screw-in bleed is also included.
Aluminum Radiator Features:
- Driver side upper inlet, 1.50"
- Passenger side lower outlet
- All-aluminum, furnace-brazed construction
- No cheap epoxy glue or crimped in gaskets
- Maximum amount of fins per inch allows greater heat transfer
- Two rows of 1" aluminum tubes (out-cools five rows of copper)
- Billet filler neck
Unlike the older SBC or BBC, the LS engine family features a thermostat that is located in the water pump housing. While this design allows for temperature and flow to be regulated before the coolant enters your engine, having the thermostat at a low point means that any air in the cooling system can easily get trapped in your engine. Air bubbles in cooling passages disrupt coolant flow, create hot-spots, and can cause overheating issues, pre-ignition, and detonation. None of these are things that your new (or used) LS will stand up to for very long without damage. Fortunately, there are steam ports in the heads that allow this trapped air to flow away from critical cooling locations to a high point outside of the cylinder heads. Since these engines utilize a closed pressurized cooling system, the steam tubes must be connected back into it at some point. Stock radiators in vehicles produced with LS engines feature a port to connect the steam lines to, and a direct-fit LS swap radiator with steam port provision is likely available for your ride - at a high price tag. Our kit allows you to spend less of your hard-earned cash on a cooling solution without sacrificing appearance under the hood.
