sure you can do that but it comes down to being careful if it's not buging dont force it just spray more wd-40

I like Pro3 and all I got was this crappy CT.
he block the bolt, because he over tighten it or because it was rusted?
I would be more concerned about cracking water neck or plastic crop under it...

that is correct he did overtighten it yup just be careful when tightening those bolts cause you can do some good damege that can be either cheap or expensive
Doesn't matter if he overtightened it before or not, they're known for being stuck on from coolant seeping through and drying inside the threads holes. Sometimes you have no choice but to snap it off, crap happens, just try to lube it up (WD-40) good before you go to town on the bolts

Just too make sure you dont snap the bolt you could aways break the bolt loose with your torque wrench, typically I dont use my torque wrench for loosing a bolt, but thats why the torque wrench do have a reverse. Torque on the themo housing bolts is 15-22 ft/lbs. So start at 40-50ft/lbs on the torque wrench. And hopefully you can break them loose before the torque wrench clicks. If they dont break loose, take it to the dealership if you are worried and have them change the themo for you. much above 50ft/lbs and you in the range of where you can shear off the bolt, especially if it has been weaked or rusted due to anti freeze. The torque wrench will keep you safe if it clicks befores the bolt break free, just go to dealership and them worry about. Then when you get home pull the bolts back out and properly apply anti-seize to them so in 24 months you dont have the same problem again. Bad news is the if bolts are really shot they can snap with less torque. Also just a suggestion rather then strain using a 12 inch rachet, use your toruque wrench assuming its a 24 inch model like most you will be able to apply a more consistent force on the bolts since your strenght is increased due to the 24 inch handle, you can more gently apply force to the bolts and break them free, just dont go gorillia on them.....use nice slow finesse. Good Luck

After flushing, make sure you get all the air out of the system. I'm more concerned about that. Pearl02.

PB Blaster or other reputable penetrating oil is a better option than WD-40 (a lubricating oil). No slight intended against WD-40 but it is not the best choice in this case.
"4.6 02 Black GT" is 101% correct about using anti-seize and a decent torque wrench.
Good luck with the flush!

I know the military's rules don't usually apply to civilian life, or even make much sense, but we've always been told to never use torque wrenches to loosen anything.. furthermore, we're told the reason they have a reverse feature isn't for loosening, but for torquing reverse thread nuts/bolts.

your right tourqe wrenches are not for loosening bolts. this can damage the tourqe wrench..
get a breaker bar.
