Worked great now I can drive my car without the heater but the AC works fine and the engine hasn't overheated in 1000+ miles with this adapter.

I'm using this as a temporary workaround while I figure out the LS Swap heater core. It fits great! I just wish they would have kindly sent the hose clamps along.

Works really well when you need to do a heater core bypass You don't have a heater anymore but your radiator fluid will leak quite a bit when the heater core has caused a leak, this ensures that the hoses are not pinched in the process

This item is perfect for bypassing the heater core on my 2000 Jeep Grand Cherokee (4.0L). One end 3/4, the other 5/8. Using a pair of hose connectors I was able to connect the hoses to the inlet and outlet of the heater core.

Perfect for LS2 GTO. The heater bypass valve at the factory broke so I tried to assemble a loop from the parts store to temporarily bypass the entire heater loop. The loop I put together didn't fit well as it had to be so big due to the size adapter in the middle. This loop snapped right in, eliminating the extra attachment I previously needed, and it fits the water pump snugly and snugly. No leaks and reusable factory clamps.

Cut my heater hoses and use barbed adapters and hose clamps (found at any auto parts store) to loop the heater hose. Running like a champ until I fix a leaking heater core in my truck.

It worked but there are two different sizes of ls water pumps and this hose was the same size. Also, the loop is too wide. Charge pump 5m3. Altogether I have four articles from all of you and 3/4 are poorly designed.

3/4 end, others 5/8. Using some hose connectors I was able to connect the hoses to the inlet and outlet of the heater core.
