ok i just put a new thermostat into my mustang and ive went through 2 gaskets so far and it still leaks just wondering what im doing wrong i have the tit of the thermostat pointed towards the radiator i put it all together and start it up and antifreeze just pours out and the bolts are as tight as i can get them

It could be a bad thermostat? Try changing it or the wrong one?

Maybe try to use some sealer and let it set up over night before starting it up.

I use silicone when I do a thermostat.

use a little rtv around the edge, ive seen when shops replace thermostat gskts they wiz wheel the gskt off the housing part andend up flattening out
that little lip that the thermostat sits in and it leaks, the rtv should take care of it no prob
