So I had a coolant leak coming from my coolant elbows. So I replaced them and no longer have a leak but now my car is overheating. Anyone have any ideas what the issue could be?

Ya I already did. I opened the valve on top of the thermostat housing until no more water would go into the radiator. Then let it get to operating temp and added a little more. Is there something else I should do? The thermostat is not even I month old so I don't think it's that but I guess it could be

You want the rad full of coolant, then let it get up to temp, then crack the bleeder open 1-2 turns so the air gets out.
From the way I read it, you are filling it through there. The coolant goes from the rad to the LIM, not the other way around.

Ok I just fixed it. I was filling the rad. I guess I still had air in the lines though. What I did was opened the tee I have installed on my heater hose to do my own flushes and no coolant was coming through and once it started flowing I closed it back up and now I'm good. I probably could of bleed it once or twice more and it would of worked too. Thanks for the help

Assuming the rest of the coolant system is now in good shape, I would replace the thermostat again. It is a common rookie mistake not to replace it after an “overheating” event. What happens is the magic wax inside the thermostat is (often) forced to leave, and from that day forward it stays shut (regardless of how new it was). Hence your car will now still over heat after the initial problem was corrected.

I'll go ahead and do that just to be safe and it's cheap. But I should be good. When I say it over heated I never let it get into the red once it hit 230 degrees I turned the car off because my car never gets anywhere close to that hot so I knew I had a problem

Exactly, if anything you can throw the extra thermostat in the tool box for a back up. Just a little tip for anyone caring, you can test these at home. Just remove it, put it in a pot of boiling water and look to see if it opens. That obviously means it opens at 212F, for more accurate assessments you can use a cooking thermometer and test for the 195F (or what ever) setting.

Ok cool I didn't know that. Good info
