Billet Swivel Thermostat Housings Water NecK 90 1.5" LS Engine Black

I’m always skeptical with third party parts. Decided to give this a shot because I needed a 90 degree housing with the option of swiveling. First impressions were good. It’s an attractive product with very nice machining. I used this with my Holley LS midmount serpentine belt system in my 53 Chevy truck. Fitment was perfect and it also fit my OEM thermostat with integrated gasket. The thermostat fit very snuggly inside the T housing. Came with the appropriate length Allen head hardware. Haven’t run coolant through it yet, but I foresee no issues as of now.

Worked great to solve the hose issue I was running into. Kind of expensive but we’ll worth it

It fits perfectly, just what I needed.

Well built! I recommend getting a high flow thermostat and a FEL-PRO Thermostat Gasket 35720. Solves the problem other reviewers are having with fitment issues. A++

not as described

This is just what I needed.

fit great i needed a tight 90 degree lower radiator hose and this worked out great.

Still have not found a thermostat that fits. I wish the seller or one of the previous purchasers would list a PART NUMBER Of a t stat that works. “ stock gm thermostat” is a worthless description. I’ll try one more t stat before I return this item. Appears to be well made , look like machined, not cast.Returning item after trying three different gm thermostats. As shown in picture, gm # 12632948 will not seal, nor would a mr. Gasket part. Obviously, based on this working for some, it depends on what water pump design you have. I can build a outlet in less time I have spent on this.
