5.3 heater by pass hose

Used this hose to delete my heater and fits great. I didn’t like the hose clamps that came with it because they are Philips head. But hose seems good

Fits on LS1/LS2 waterpump. Correct type of hose.

It fits perfectly on my LS1/LS2 water pump. The hose is also the correct material for coolant. It came with both hose clamps.

Worked fine

It's a basic heater core bypass hose for a Chevy. It fits well and comes with the stainless hose clamps.
