Overheating after assembly
Put my engine back together after a timing chain failure and it runs pretty good but it starts overheating right away without leaking coolant.
It's not the fan.
I replaced the coolant plug sensor and I might have put some hoses on wrong, maybe you could tell me by looking at this picture.

Did you burp the system? You have to leave the cap off the coolant tank and leave the car idle until it reaches full temp and add coolant slowly. You can't get all the air out of the system until the T-stat opens.

Oh of course it's gotta be warm when you bleed it makes sense. Thanks. But do you really think a few air bubbles can render your entire cooling system useless like that?

It never got over 195 before in tropical climate. Now it just overheats right away, its get warm and then goes straight to 210 and seems like it just wants to keep rising but I shut it off it's as if the coolant isn't even circulating.

Yes they do. Just changed my antifreeze and it was a pain to get air out so it circulates properly again.

Yep....must be bled properlySimple procedure done with engine cool. Follow small hose on reservoir to where it meets metal t-fitting. Disconnect small hose at t-fitting. Fill antifreeze reservoir and replace cap securely. Blow in end of small hose which will force antifreeze slowly into the engine. Keep an eye on volume in reservoir and refill as necessary. Keep doing this until antifreeze burps out the small t-fitting. Replace hose and top reservoir. DONE

No, until it burps out thru the t-fitting where you disconnected the hose. Blowing in the hose pressurizes the reservoir slowly forcing antifreeze thru the system. Works great and I've used this technique probably 50 times...always successfully.
