I have a bad heater core on my 2010 Camaro SS LS3. I could fix it, but it would be very expensive as the entire dash needs to come off. Since I don't use my heater at all because I live in Southern California, I have no further use for it, so this little hose came in handy.

I had my heater core blow on my ls swapped 84 trans am. I installed this loop to bypass the heater core and get me home. Worth the money.

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 leakThis makes sure it wont pinch the hoses also when you do it

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.

Great quality hose. Needed to bypass the heater core in my 1965 Chrysler 300 due to a leak :( and this allowed me to loop the coolant right back to the engine so easily and discreetly.

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.
