LS Swap Radiator Hose Adapter w/ Steam Port, 1.5 Inch - 1.25 Inch

Runner-Up for the 2020 SEMA Best New Street Rod/Custom Car Product Award!

If you've decided to add modern power to your ride using an LS series engine, this LS Steam Port Radiator Hose Adapter 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.

• 1.25" end - matches water pump outlet size
• 1.50" end - matches upper radiator inlet size
• Black finish blends in with radiator hoses

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. This piece allows you to spend less of your hard-earned cash on a cooling solution without sacrificing appearance under the hood.
