Coolant leaking!

Hello Guys I am new to the forum but I have read many posts and I wanted to ask for your advise.

Do any of you know where i can find the top portion that connects to the expansion tank only ?

part # 17127526856
I can't find the top hose leading to the expansion tank by itself. The rest has already been replaced. Also If you wiggle the hose for part # 17127509967 at the expansion tank, it leaks!!! its small but it only leaks if i put a tiny bit of pressure. I imagine this is also one of the places where coolant leaks just because I see the puddles underneath.

I have also noticed that the Temperature sensor gasket leaked. I have noticed performance issues with the vehicle jerking when im running at 50-65 mph on the freeway. The temperature sensor has a round gasket ( not sure if thats correct) I used sealant and I no longer see coolant coming out of it but I now have a check engine light. I am assuming this is due to a bad temperature sensor and should be replaced.

Now, I have a new radiator I was able to snatch for $153 with free shipping. I noticed water running along the side of the radiator at one point after I applied pressure. That took me to the conclusion that my radiator is also bad. Please share your thoughts on this. I will be working on the car this weekend to try and get it repaired. No way im taking this to the stealership. They gave me a $700 estimate
