Coolant hose T connector

[Zayzay09]

There’s a “plastic” ring that goes in the T connector but I can’t figure out for the life of me where it goes in the T connector. It’s not one of the rubberized o rings. It’s a plastic ring. Any help is appreciated. Thanks.

It's on the t-hose side, and as far as every single one I've replaced is only serviceable with the hose. Best to replace the t-hose and upper radiator hose as well, that quick connect fitting is known for leaks.

I know it’s on the T hose. But it has 3 sides. Which side does it go on? And yea. Mines is leaking on thermostat side.

I’m not sure what hose you’re looking to replace. However, I recently had a leak on the passenger side heater hose where is connects to the tube that connects to the block / head. I tried to buy a new hose but Ford said there are ZERO in North America. All in back order with no timeframe to fill it.

That entire assembly has been updated to a newer style Y assembly with better sealing FYI. If you disturb the seal on the original union, many times it wont seal right again.

Oh, my bad . There's one on the thermostat housing side (white plastic "seal") and one on the upper radiator hose.
