Review: Real good part to do heater core bypass - Work really good when you got to do a heater core bypass, you wont have your heater anynore but your radiator fluid will quite leaking if the heater core caused it to leak This makes sure it wont pinch the hoses also when you do it
Review: Fits Nice on LS2 - Fit perfectly on a LS2 GTO. Garbage factory heater bypass valve broke so I tried to cobble together a loop from the parts store to bypass the whole heater loop temporarily. The loop I cobbled together fit poorly as it had to be so big due to having a size adapter coupler in the middle. This loop dropped right in, eliminated the extra fitting I needed before and is nice and snug to the water pump. Zero leaks and just reused the factory hose clamps.

- Used to loop the heater hose outlets of your LS/LT engine water pump
- Compatible with all LS or LT series engines from 1998 and newer

### ⭐⭐⭐⭐⭐ Fits Nice on LS2

### ⭐⭐⭐⭐⭐ Works on just about any vehicle
*by B***C on June 30, 2019*

Cut my heater hoses and used barb end adaptors and hose clamps (any auto parts store) to loop back the heater hose. Works like a champ until I can replace the leaking heater core in my truck.
