Overall Assessment

Customers frequently praise the product's perfect fitment, especially for LS swap projects, and its adjustable neck feature that ensures a clean hose run from motor to radiator. They value its high quality, durability, and 360-degree swivel functionality. Some users noted it resolved their hose routing issues. However, problems with sealing and thermostat installation occurred in a few cases. The product's absence of an 'O ring gasket' was an occasional critique. Despite this, customers were generally satisfied and would recommend the product to others.

It doesn't come with the ''O ring gasket''.

The proper O rings should be stocked and sold alongside this product. I ordered 2 and they cannot seal this part properly. I have to look locally now and I have 2 wall hangers I don't trust.

I would consider buying this again.

This piece took care of my hose routing problem, but had trouble installing the thermostat. The inside diameter of the housing is too small. had to file down the thermostat to install it

I used this on an ls swapped S-10. Corrected the angle to the radiator and made it easier to find a hose to fit.

Doing a LS swap on a 89 Comanche. Needed to figure how out to fit the hoses better for the water pump and radiator. Fits perfect and is just what I needed to make the swap work.

Had to trim the thermostat seal to fit into the housing as it was too large a diameter. Leaked when I run engine.
