Hi everyone, changed a bypass hose and adding coolant currently. I know there is a bleeder bolt on the top of the thermostat housing. However when I try to take it off it wont budge? If I turn it to loose, the entire tube turns with it and I am afraid it will snap? Anyone else encounter this?
 
Are you using a wrench on the hex portion of the tube below the bleeder bolt to keep the tube from turning?
 
Use a 19mm wrench on the part below the bleeder screw as stated by JB31 I'm sure it's a 19 because I literally just did mine today
 
oh! I am not! I thought it was just one bolt. Didnt know that I have to hold it on the bottom! Thank you guys!

So to clarify. I use the 19mm to turn the top while using an adjustable/open wrench on the bottom to hold it?
 
I wouldn't use adjustable wrenches the metal isn't that strong one slip and you need another tstat housing too much play in adjustable wrenches
